1. Insert the 560mm x 15mm wing joiner into the fuselage.

IMPORTANT : The wing joiner is stored during transport inside the fuselage, clipped to the side under the battery hatch.

2. Verify the wing locks are in the unlocked position.
3. Slide the wings onto the wing joiner.
4. Move the lock into the locked position on both wing halves. If the locking pin doesn’t drop into place, wiggle the wing half into place while moving the lock.

Slide the lock into the unlocked position to disengage for removing the wings.

Wing Slat Mount Covers (with Vortex Generators) or Leading Edge Slat Installation (Optional)

Select if you want to use the vortex generators or leading edge slats,

1. To remove the vortex clips, carefully lift from the trailing edge of clip.
2. Insert the slat clips at approximately a 45 degree angle from leading edge.
3. Press the part firmly into place until it snaps into place around the mounting rod in the wing.

Use the leading edge slats to maximize STOL performance for take off and landing.
Expect to adjust elevator trim when using the leading edge slats.

For high speed flight and aerobatics, wing slat mount covers
(with vortex generators) are recommended.

Propeller Installation

WARNING: Never install a cracked, nicked or otherwise damaged propeller or spinner.

NOTICE: If the propeller is not balanced it can cause vibration that could result in damage to the motor and/or mount. It can also cause the stabilization system to not operate correctly and/or decrease the life of the servos.

1. Install the propeller adapter onto the motor with three M3 x 8mm screws, using a 2.5mm hex driver.
2. Install the propeller and nut on the propeller shaft. Get a firm grip on the propeller and motor to hold them secure while tightening the nut. Tighten the nut with a 15mm wrench or socket driver to secure the propeller in place. Ensure the nut is tight enough so the propeller cannot slip.
IMPORTANT: Do not overtighten the prop nut as damage to the propeller or threads may result.
3. Install the spinner and secure in place with an M3 x 10mm button head machine screw, washer and lock washer using a 2mm hex driver. IMPORTANT: Tighten until secure, but avoid over tightening the spinner screw. The spinner cone may become deformed and not spin true if over-tightened.

WARNING: After installation, thoroughly test the propeller with the model facing away from yourself and others. If a propeller is not installed securely it may fly off when the motor spins, and could cause bodily injury.

Battery Installation and ESC Arming

The Spektrum 3200mAh 6S 22.2V Smart LiPo 30C battery with an IC5 connector (SPMX326S30 or SPMX32006S30) is recommended. A 4S to 6S 3200-5000mAh LiPo battery with an IC5 or EC5 connector is required, refer to the Optional Parts List for other recommended batteries. If using a battery other than those listed, the battery should be within the range of capacity, dimensions and weight of the Spektrum Li-Po battery packs to fit in the fuselage.

NOTICE: There are four battery mounting positions to allow for different size batteries and flying styles. Always verify the model balances within the recommended CG range before flying. Attempting to fly the model with an aft CG will cause the model to be unstable.

1. Lower the throttle and throttle trim to the lowest settings. Power on the transmitter, then wait 5 seconds.
2. Remove the battery hatch.
3. Pull up on the battery tray locking tab and move the tray forward to release the tray.
4. For added security, apply the loop side (soft side) of the optional hook and loop tape to the bottom of your battery, and the hook side to the battery tray.
5. Secure using the hook and loop straps.
6. Install the fully charged battery and tray in the desired position of the battery compartment. Slide the tray rearward to engage all four tabs on the bottom of the tray.
7. Push down on the battery tray locking tab to secure the battery in position.
8. Connect the battery to the ESC (the ESC is now armed).

CAUTION: Always keep hands away from the propeller. When armed, the motor will turn the propeller in response to any throttle movement.

9. Keep the aircraft immobile and away from wind or the system will
not initialize.
• The motor will emit two even tones when the battery is connected and the ESC has a throttle signal.
• The motor will then emit a series of slow single tones to indicate the number of cells in the LiPo pack connected to the ESC (Four beeps indicates a four-cell LiPo pack. Six beeps indicates a six-cell LiPo pack).
• Two ascending tones indicate the ESC is armed.
• The orange LED will illuminate on the receiver when it is initialized.
10. Reinstall the battery hatch.

General Binding Tips and Failsafe BNF

• The included receiver has been specifically programmed for operation of this aircraft. Refer to the receiver manual for correct setup if the receiver is replaced.
• Keep away from large metal objects while binding.
• Do not point the transmitter’s antenna directly at the receiver while binding.
• The orange LED on the receiver will flash rapidly when the receiver enters bind mode.
• Once bound, the receiver will retain its bind settings for that transmitter until you re-bind.
• If the receiver loses transmitter communication, the failsafe will activate. Failsafe moves the throttle channel to low throttle. Pitch and roll channels move to actively stabilize the aircraft in a descending turn.
• If problems occur, refer to the troubleshooting guide or if needed, contact the appropriate Horizon Product Support office.

Transmitter and Receiver Binding / Enabling and Disabling SAFE Select BNF

The BNF Basic version of this airplane includes SAFE Select technology, enabling you to choose the level of flight protection. SAFE mode includes angle limits and automatic self leveling. AS3X mode provides the pilot with a direct response to the control sticks. SAFE Select is enabled or disabled during the bind process.
With SAFE Select disabled the aircraft is always in AS3X mode. With SAFE Select enabled the aircraft will be in SAFE Select mode all the time, or you can assign a switch to toggle between SAFE Select and AS3X modes.
Thanks to SAFE Select technology, this aircraft can be configured for full- time SAFE mode, full-time AS3X mode, or mode selection can be assigned to a switch.
IMPORTANT: Before binding, read the transmitter setup section in this manual and complete the transmitter setup table to ensure your transmitter is properly programmed for this aircraft.
IMPORTANT: Move the transmitter flight controls (rudder, elevators, and ailerons) and the throttle trim to neutral. Move the throttle to low before and during binding. This process defines the failsafe settings.
You can use either the bind button on the receiver case or the conventional bind plug to complete the binding and SAFE Select process.
SAFE Select can also be activated via Forward Programming in compatible transmitters.

Using The Bind Button…

Using The Bind Plug…

Control Surface Centering

After assembly and transmitter setup, confirm that the control surfaces are centered. The model must be powered up, bound to the transmitter in AS3X mode, with the throttle left at zero. When enabled, SAFE mode is active at power up. AS3X mode is activated when the throttle is raised above 25% for the first time after being powered on. It is normal for the control surfaces to respond to aircraft movement if the aircraft is in AS3X or SAFE modes.

1. Verify the trims and subtrims on your transmitter are zero
2. Power the model in AS3X mode and leave the throttle at zero
3. Look at the tip of each control surface and verify it is mechanically centered.
4. If adjustment is required, turn the ball link on the linkage to change the length of the linkage between the servo arm and the control horn.

NOTICE: Be aware of the pushrod bottoming out in the ball linkage. Do not thread the pushrod too far into the ball link or the pushrod will damage the ball link and protrude into the area needed for the control ball. Both ends of the pushrod may be threaded in the ball links for larger changes.

Center of Gravity (CG)

The Center of Gravity (CG) location is measured from the leading edge of the wing. The CG will be affected by battery changes. Always verify the CG is within the recommended range before flight.

IMPORTANT: For general flying place the CG at 105mm from the leading edge. For aerobatics place the CG at 110mm from the leading edge.

CAUTION: Install the battery but do not arm the ESC while checking the CG. Personal injury may result.

SAFE® Select Switch Designation BNF

Once SAFE Select is enabled, you can choose to fly in SAFE mode full-time, or assign a switch. Any switch on any channel between 5 and 9 can be used on your transmitter.

TIP: If model has a reversing ESC feature, Aux2 is not available for safe select.

If the aircraft is bound with SAFE Select disabled, the aircraft will be in AS3X mode exclusively.

CAUTION: Keep all body parts well clear of the propeller and keep the aircraft securely restrained in case of accidental throttle activation.

IMPORTANT: To be able to assign a switch, first verify:

• The aircraft was bound with SAFE Select enabled.
• Your choice for the SAFE Select switch is assigned to a channel between 5 and 9 (Gear, Aux1-4), and travel is set at 100% in each direction.
• The aileron, elevator, rudder and throttle direction are set to normal, not reverse.
• The aileron, elevator, rudder and throttle are set to 100% travel. If dual rates are in use, the switches need to be in the 100% position.

See your transmitter manual for more information about assigning a switch to a channel.

TIP: If a SAFE Select switch is desired for your 6 function aircraft, and you are using a 6 channel transmitter, the SAFE Select switch channel will have to be shared with either channel 5 or 6 of the transmitter. This does not apply to the NX6. Please refer to your NX6 instruction manual for further details.

Assigning a Switch

1. Power on the transmitter.
2. Power on the aircraft.
3. Hold both transmitter sticks to the inside bottom corners, and toggle the desired switch 5 times quickly (1 toggle = full up and down).
4. The control surfaces of the aircraft will move, indicating the switch has been selected.
Repeat the process to assign a different switch or to deactivate the current switch.

SAFE Select Switch Assignment Stick Positions

This example of the channel monitor shows the stick positions for assigning a switch, the switch selection on Aux3, and +/- 100% travel on the switch.

Forward Programming

11. Scroll down to Poles, enter 14.
12. Return to the main screen.

Dual Rates and Control Throws

Program your transmitter to set the rates and control throws based on your experience level. These values have been tested and are a good starting point to achieve successful first flight.
After flying, you may choose to adjust the values for the desired control response.

The table to the right shows the factory settings for the control horns and servo arms. These settings, in conjunction with the low rate transmitter settings, are intended for intermediate level pilots to help ensure a successful flight.
Fly the aircraft at these factory settings before making changes.

Control Surface Direction

Switch on the transmitter and connect the battery. Use the transmitter to operate the aileron, elevator, rudder and flap controls. View the aircraft from the rear when checking the control directions.

Elevator

1. Pull the elevator stick back. The elevators should move up, which will cause the aircraft to pitch up.
2. Push the elevator stick forward. The elevators should move down, which will cause the aircraft to pitch down.

Ailerons

1. Move the aileron stick to the left. The left aileron should move up and the right aileron down, which will cause the aircraft to bank left.
2. Move the aileron stick to the right. The right aileron should move up and the left aileron down, which will cause the aircraft to bank right.

Rudder

1. Move the rudder stick to the left. The rudder should move to the left, which will cause the aircraft to yaw left.
2. Move the rudder stick to the right. The rudder should move to the right, which will cause the aircraft to yaw right.

Flaps
1. Move your flap control switch down to the partial position.
2. Confirm that the wing flaps move down.
3. Move flap control switch to the full flap position.
4. Confirm the flaps move farther down than in step two.

AS3X® Control Response Test

WARNING: Do not perform any testing or maintenance with the propeller installed on the aircraft. Serious injury or property damage could result from the motor starting inadvertently.

This test ensures that the AS3X control system is functioning properly.
Assemble the aircraft and bind your transmitter to the receiver before performing this test.

1. Raise the throttle just above 25%, then lower the throttle to activate

AS3X technology.

WARNING: Keep all body parts, hair and loose clothing away from spinning motor, as these items could become entangled.

2. Move the entire aircraft as shown and ensure the control surfaces move in the direction indicated in the graphic. If the control surfaces do not respond as shown, do not fly the aircraft. Refer to the receiver manual for more information.

Once the AS3X system is active, control surfaces may move rapidly. This is normal.

AS3X remains active until the battery is disconnected.

In Flight Trimming

During your first flight, trim the aircraft for level flight at 3/4 throttle. Make small trim adjustments with your transmitter’s trim switches to straighten the aircraft’s flight path.

After adjusting trim do not touch the control sticks for 3 seconds. This allows the receiver to learn the correct settings to optimize AS3X performance.
Failure to do so could affect flight performance.

Flying Tips and Repairs

Consult local laws and ordinances before choosing a flying location.

Flying Field
Always choose a wide-open space for flying your aircraft. It is recommended that you fly at a designated RC flying field. Always avoid flying near houses, trees, wires and buildings. Avoid flying in areas where there are many people, such as parks, schoolyards, or soccer fields.

Range Check your Radio System
Before you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information.

Understanding Oscillation
Once the AS3X system is active (after advancing the throttle for the first time), you will normally see the control surfaces react to aircraft movement. In some flight conditions, you will see oscillation. If oscillation occurs, decrease airspeed. If oscillation persists, refer to the Troubleshooting Guide for more information.

Takeoff
Place the aircraft in position for takeoff (facing into the wind). Set your transmitter in low rate and gradually increase the throttle from ¾ to full and steer with the rudder. As the airplane gains speed, gently pull back on the elevator and climb to a comfortable altitude. You may also set flaps to half travel for shorter takeoffs.

Flying
Fly the airplane and trim it for level flight at ¾ throttle with flaps up. After adjusting trim in flight do not touch the control sticks for 3 seconds. This allows the receiver to learn the correct settings to optimize AS3X performance.

Landing
Make sure to land the aircraft into the wind. Start to slow the model down to an approach speed and set the flaps to half travel. If landing in windy conditions, land at half flap travel. If flying in light winds, set flaps to full for final approach. With flaps and retracts extended, fly the aircraft to approximately 36 inches (90 cm) or less above the runway, using a small amount of throttle for the entire descent. Keep the throttle on until the aircraft is ready to flare. During flare, keep the wings level and the aircraft pointed into the wind. Gently lower the throttle while pulling back on the elevator to bring the aircraft down on its wheels.

Refer to the Dual Rates and expo chart for proper flap to elevator mix to help reduce the pitching tendency from flaps.

NOTICE: When using flaps with this airplane, down elevator to flap mixing is required. Failure to do so may result in loss of control or a crash.

NOTICE: If a crash is imminent, reduce the throttle and trim fully. Failure to do so could result in extra damage to the airframe, as well as damage to the ESC and motor.

NOTICE: After any impact, always ensure the receiver is secure in the fuselage.

If you replace the receiver, install the new receiver in the same orientation as the original receiver or damage may result.

NOTICE: Crash damage is not covered under warranty.
NOTICE: When you are finished flying, never leave the airplane in direct sunlight or a hot, enclosed area such as a car. Doing so can damage the foam.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The ESC protects the flight battery from over-discharge using Low Voltage Cutoff (LVC).
Before the battery charge decreases too much, LVC removes power supplied to the motor. Power to the motor pulses, showing that some battery power is reserved for flight control and safe landing.

Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Charge your Li-Po battery to about half capacity before storage.
During storage, make sure the battery charge does not fall below 3V per cell. LVC does not prevent the battery from over-discharge during storage.

NOTICE: Repeated flying to LVC will damage the battery.

TIP: Monitor your aircraft battery’s voltage before and after flying by using a Smart LiPo Battery Checker and Servo Driver (SPMXBC100, sold separately).

Repairs Thanks to the EPO foam material in this aircraft, repairs to the foam can be made using virtually any adhesive (hot glue, regular CA, epoxy, etc). When parts are not repairable, see the Replacement Parts List for ordering by item number. For a listing of all replacement and optional parts, refer to the list at the end of this manual.

NOTICE: Use of CA accelerator on your aircraft can damage paint. DO NOT handle the aircraft until accelerator fully dries.

Post Flight Checklist

• Disconnect the flight battery from the ESC
• Power OFF the transmitter
• Remove the flight battery from the aircraft
• Recharge the flight battery
• Repair or replace all damaged parts
• Store the flight battery apart from the aircraft and monitor the battery charge
• Make note of the flight conditions and flight plan results, planning for future flights

Receiver Installation (PNP)

The Spektrum AR637T receiver is recommended for this airplane. If you choose to install another receiver, ensure that it is at least a 6-channel full range receiver.
Refer to your receiver manual for correct installation and operation instructions.
IMPORTANT: A Smart compatible Spektrum receiver is required for thrust reversing, and telemetry information from the ESC.

Installation (AR637T shown)

1. Mount the receiver parallel to the length of the fuselage as shown, with the servo ports facing rearward. Use double-sided servo tape.

CAUTION : Incorrect installation of the receiver could cause a crash.
2. Attach the appropriate control surfaces to the their respective ports on the receiver using the chart in the illustration.

Thrust Reversing (Optional)

The Avian™ Smart ESC in this aircraft is equipped with thrust reversing, but it must be enabled before it will function. Reversing the motor can be helpful when taxiing, or for shortening the ground roll after landing. Activating the designated switch reverses motor rotation, throttle will still control motor speed.

CAUTION: Never attempt to use thrust reversing in flight. Applying reverse thrust while in flight will result in loss of control and possibly a crash. Crash damage is not covered under warranty.

IMPORTANT: Thrust reversing requires a Spektrum receiver with Smart Throttle and a Spektrum transmitter with a minimum of 7 channels. The Avian ESC is backwards compatible with conventional receivers (PWM output signal) for normal operation, but reversing functions are only available with Smart Throttle technology.

Thrust Reversing Setup

Transmitter
On the transmitter, select an open channel (not already in use), and assign it to an open switch, or button. Use different channels for thrust reversing and SAFE Select. Motor reversing is assigned to Aux 2/Channel 7, by default, in the Smart ESC. If SAFE Select and the ESC are assigned to the same channel, the motor will reverse in flight.

CAUTION: Do not assign thrust reversing and SAFE Select to the same channel. Doing so will reverse the motor when SAFE Select is enabled during flight, resulting in a crash.

ESC

Set up the transmitter according to the setup chart, and bind your transmitter to the airplane. The airplane must be powered on and bound to the transmitter to access the Smart ESC programming.
As an alternative, it is possible to program the ESC with the Smart ESC Programming Box (SPMXCA200, optional, not included).

IMPORTANT: Do not power the motor on before attempting to enter ESC programming, the programming menu is locked once the motor is powered on. If you need to enter ESC programming after the motor has been powered, you must power cycle by disconnecting the battery and plugging it in again.

Tire Service

In the event of severe damage, replacement tires are available (EFL-1333, EFL-1393 tire only). Minor repairs can be made with an inner tube repair kit to the inside of the tire.

To replace or repair the tire:

1. Insert a small flat-head screwdriver into the slot of the hubcap and carefully pop the hubcap from the wheel.
2. Remove the wheel collar from the axle.
3. Use a 1.5mm hex driver to remove the bead locks.
4. Replace the tire, and/or inflation valve as required for your repair.
5. Tighten each beadlock screw in small increments alternating evenly across each of the screws.
6. Inflate tire to your desired diameter. Do not exceed 5.75”(146mm) diameter.
7. Insert rubber plug into air valve.

IMPORTANT: Over inflating can shorten the life of the tire. 3psi maximum pressure.

Tire Pressure and Diameter
Set your desired tire diameter with tire pressure. Inflating the tires will increase the tire diameter, reducing pressure will reduce the diameter. We recommend inflating the tires between 5.00” (127mm) and 5.75” (146mm).
Use lower tire pressure for rough surfaces, and higher tire pressure for smooth surfaces. Minimum tire diameter is 5.00” (127mm).

Inflating and Deflating the Tires
Attach the included air hose extension to the air pump. Screw the needle into the end of the air hose. Wet the needle before inserting it into the air valve in the wheel hub for inflation. Do not inflate the tires beyond 5.75” (146mm) diameter (3psi max). The tire pressure is too low to measure with most bicycle or automotive tire pressure gauges. Low pressure gauges for sports balls have the correct range and are available at sporting goods stores.
Insert the needle for pumping into the air valve without the pump to reduce tire pressure. Air will immediately be released from the tire.

Motor Service

CAUTION: Always disconnect the flight battery before performing motor service.

Disassembly

1. Remove the spinner with a 2mm hex driver.
2. Remove the propeller nut with a 15mm wrench. Remove the propeller.
3. Remove the four screws from the front of the cowling and remove the cowl from the fuselage.
4. Remove the four 3 x 16mm screws and the motor with X-mount from the fuselage.
5. Disconnect the motor wires from the ESC wires.
6. Remove the four 3 x 6mm Phillips head machine screws and motor from the X-mount.

Assembly

Assemble in reverse order.

• Correctly align and connect the motor wire colors with the ESC wires.
• Install the propeller with the size numbers facing forward. The propeller may require balancing.

NOTICE: If the propeller is not balanced it can cause vibration that could result in damage to the motor and/or mount. It can also cause the stabilization system to not operate correctly and/or decrease the life of the servos.

Float Installation (Optional, floats not included)

Float Set (EFLA550), float struts included with airplane

1. Remove the main landing gear assembly. The tail wheel assembly may be left on the airplane or removed for operation on floats.
2. Mount the floats on the vertical and diagonal struts included with the Super Timber, with the front spreader bar from the float set, as shown. Use the screws included with the float set to secure the floats to the landing gear assembly. The float with the water rudder should be on the left side of the aircraft.

3. Install the water rudder pushrod which connects to the water rudder control horn with the easy connector that is pre-installed on the rudder control horn.
Connect it to the clip on the float, install a clip on the left rear vertical strut, and secure it with an M2x8mm screw and M2 nut.

4. Locate the two mounting locations for the float mounting brackets on the bottom of the fuselage.
5. Insert the vertical and diagonal struts into the mounting brackets.
6. Secure the front stuts with two plastic keepers, and four M2.5x10mm self tapping screws with a 1.5mm hex driver.
7. Secure the rear landing strut with the single plastic keeper and one M3x10mm self tapping screw with a 2mm hex driver.
8. Secure the water rudder pushrod into place in the clips along the fuselage.
9. Center the water rudder with the air rudder centered and set the pushrod position with a 2mm hex driver.

Disassemble in reverse order.

Water deflectors, included with airplane

Install the water deflectors on the inside of both floats as shown, to prevent water from spraying into the propeller. Align the double sided tape on the back of the water deflector with the edge of the float. The water deflectors should be installed 35mm behind the nose of the floats, with the bottom edge of the water deflectors 10mm below the edge of each float.

Flying Off Water

Flying off water poses a higher risk because piloting errors or water conditions can cause the aircraft to become stranded. Only fly from the water when a level of comfort has been achieved flying the aircraft from the ground.

Pre-Flight
Ensure the optional floats are secure on the fuselage and the water rudder is correctly connected and operating with the main rudder before putting the aircraft in the water. Select an area to fly that does not have water currents, salt water, or debris. Look around the flight area and be aware of trees, docks, buoys, or other obstacles. Always fly with a spotter and avoid swimmers, boaters, people fishing, and people on the beach.

Taxiing
When taxiing, use low throttle settings and the rudders to steer. Hold up elevator to help keep the rudder in the water and the nose of the floats above the surface. Steer into the wind when turning, and crab into the wind if crosswind taxiing is required. When turning or crabbing into the wind, apply aileron against the wind to keep the upwind side of the wing down and prevent the aircraft from being flipped over. Do not apply down elevator when the airplane is taxiing or during the takeoff run.

On Step
When speed increases with throttle, the floats will rise out of the water and begin to plane on the surface of the water, riding “on step.” The floats will come on step at a speed below flight speed, this is a transitional phase when the aircraft is not up to flight speed yet. This is considered a high speed taxi. Do not attempt to take off as soon as the aircraft comes on step. Use low to medium throttle and hold up elevator to manage speed on the water during a high speed taxi.

Takeoff
To lift off from the water, set the flaps to the takeoff position, hold up elevator and accelerate the aircraft to bring it on step. Relax the up elevator as the airplane comes on step and accelerate to flight speed with full throttle. When the aircraft is travelling at a sufficient speed, pull back slightly on the elevator to rotate for liftoff.

Landing
To land on the water, set the flaps to the landing position, and fly into the wind. Reduce the throttle to a low setting but keep some power during the approach. As the aircraft settles into ground effect, reduce the throttle fully and hold up elevator to flare. Hold up elevator through the touch down and as the airplane decelerates on the water.

WARNING: Never attempt to retrieve a downed aircraft by swimming unless you are sufficiently trained and/or there is another person available to respond in the case of an emergency.

CAUTION: Have a plan for retrieval in the event the airplane becomes stranded. Never retrieve a downed model in the water alone.

CAUTION: If at any time water splashes in the fuselage while flying from water, bring the airplane to shore, open the battery hatch and immediately remove any water that may have gotten in the fuselage. Leave the battery hatch open overnight to let the inside dry out and to prevent moisture damage to the electronic components. Failure to do so could cause the electronic components to fail, which could result in a crash.

TIP: Use a fishing pole with heavy line as a retrieval tool. Attach a tennis ball to the line, and throw the ball past a stranded aircraft to retrieve it.

AMA National Model Aircraft Safety Code

Effective January 1, 2018
A model aircraft is a non-human-carrying device capable of sustained flight within visual line of sight of the pilot or spotter(s). It may not exceed limitations of this code and is intended exclusively for sport, recreation, education and/or competition. All model flights must be conducted in accordance with this safety code and related AMA guidelines, any additional rules specific to the flying site, as well as all applicable laws and regulations.

As an AMA member I agree:

• I will not fly a model aircraft in a careless or reckless manner.

• I will not interfere with and will yield the right of way to all human-carrying aircraftusing AMA’s See and Avoid Guidance and a spotter when appropriate.

• I will not operate any model aircraft while I am under the influence of alcohol or any drug that could adversely affect my ability to safely control the model.

• I will avoid flying directly over unprotected people, moving vehicles, and occupied structures.

• I will fly Free Flight (FF) and Control Line (CL) models in compliance with AMA’s safety programming.

• I will maintain visual contact of an RC model aircraft without enhancement other than corrective lenses prescribed to me. When using an advanced flight system, such as an autopilot, or flying First-Person View (FPV),
  I will comply with AMA’s Advanced Flight System programming.

• I will only fly models weighing more than 55 pounds, including fuel, if certified through AMA’s Large Model Airplane Program.

• I will only fly a turbine-powered model aircraft in compliance with AMA’s Gas Turbine Program.

• I will not fly a powered model outdoors closer than 25 feet to any individual, except for myself or my helper(s) located at the flightline, unless I am taking off and landing, or as otherwise provided in AMA’s Competition Regulation.

• I will use an established safety line to separate all model aircraft operations from spectators and bystanders.
