General Tips for this Quick Assembly Guide
This guide will go through a recommended sequence of assembly, including most pertinent information for each step, but without any major details. It will include a small quantity of pictures wherever necessary to clarify or illustrate these steps.
This information should be enough to put the RV-8 60E G2 together but if you have any doubts please reference the full manual.
Note: Do not use thread locker when attaching plastic parts, the parts will soften and fail.
Note: If you have the night version of the RV-8 60E G2 we recommend that you dry assemble the airframe and test all the lights before bonding anything permanently in place.

Assembly Sequence

Landing Gear
The diagram to the right shows the orientation of the landing gear, note this when assembling and mounting.

1. Mount the main landing gear to the fuselage using four M3x20 screws and thread locker.

2. Mount the inside wheel pants and retaining plates to the main landing gear using M3x12 self tapping screws.
   

3. Mount the main gear shafts to the landing gear using a washer, an M5 nut and thread locker.

4. Secure the outside of the wheel pants to the inside using five M3x8 self tapping screws per side.

5. Insert the tail wheel into the slot in the bottom of the rudder (orientation showing in picture to the right).

6. Secure the retaining plate to the rudder fin using three M3x7 self tapping screws

Vertical Fin
The vertical fin assembly uses the short carbon fiber rod for reinforcement.

1. Dry fit the vertical fin and reinforcement rod to the fuselage.
2. Once everything fits correctly, remove the carbon fiber rod and lightly scuff it with 220 grit sandpaper to aid in adhesion. Clean all surfaces with rubbing alcohol before bonding.
3. Bond the vertical fin assembly to the fuselage using 30-minute epoxy adhesive. Ensure that you get adhesive not only on all the mating surfaces but also on the carbon fiber rod.
4. Clamp the vertical fin assembly in place while the adhesive dries. Note: Do not apply tape directly to any painted part as this will strip the paint off the part.

Horizontal Stabilizer

1. Insert and roughly center the carbon fiber horizontal stabilizer tube in the fuselage.
2. Insert both halves of the horizontal stabilizer onto the tube. Ensure that the control horn faces the bottom of the fuselage and that the elevator jointer tabs line up properly.
3. If you have the night version, connect the LED power connectors.
4. Once both halves of the horizontal stabilizer are seated in place secure them each using two M3x8 self tapping screws.

Rudder and Elevator Linkages
Install the rudder and elevator linkages now but after setup you may need to re-center servo arms and ensure that the pushrods are the correct length to center the control surfaces.

1. Using M3x6 screws, Install the servo arms on the servos so that they are perpendicular to the servos and face towards the ground. Once radio setup is complete, remove these screws and re-install them with thread locker.
2. Install the linkages between the servos and the corresponding control surface using the following hardware sequence: M2x10 Machine Screw → M2 Washer →Servo Arm or Control Horn → M2 Lock Nut.
3. The following diagrams show the positions of the linkages:

Note: Do not use thread locker on the bolts holding the push rods to the servos or the control horns! Using thread locker will weaken the plastic, void your warranty and cause your airplane to crash!

Wing Installation

1. Remove the hatch from the fuselage.
2. Insert and roughly center the carbon fiber wing tube in the fuselage.
3. Slide the left and right wing panels onto the tube. Ensure the servos orient to the bottom of the fuselage.
4. Connect the single wing connector from each wing panel to the corresponding connector on the fuselage.
5. If you have the night version, connect the LED power connectors.
6. Seat the wings completely in the wing saddles and secure the wings using the thumb screws through the aluminum tabs.

Exhaust Installation

1. Use medium CA to bond the scale exhaust pieces to the exhaust port on the bottom of the fuselage.

Motor and Cowling Installation

1. Install the prop adapter on the front of the motor using the provided socket head hex screws and thread locker.
2. Install the x-brace on the back of the motor using four M4x8 flat head screws and thread locker.
3. Mount the motor to the firewall using four M4x22 button head screws and thread locker.
4. Connect the the three motor leads to the ESC leads in the fuselage (when you test the motor, if it spins in the wrong direction you can reverse the direction of rotation by swapping any two leads).
5. Install the cowling using two M3x8 screws through the cooling holes in the cowling.
6. Note: Do not install the propeller on the airplane for now, this will be installed after radio setup and testing.

Aura Configuration

DEFAULT AURA CONNECTIONS
S1 – Throttle
S2 – Left Aileron
S3 – Right Aileron
S4 – Elevator
S5 – Rudder
S6 – Left Flap
S7 – Right Flap
S8 – Water Rudder (optional, with floats)
Port B – Serial Receiver Input
Mini Port A&B – Remote Receiver Inputs Aura 8 Auto-Detect
Once your receiver is bound, powered, and connected to the Aura, the Aura will begin the Auto-Detect process to learn what type of receiver you are using and set itself up for that specific system. Auto-Detect is indicated by a series of sweeping LEDs of various colors. After Auto-Detect is completed, verify that Aura is on and receiving data from your receiver by looking at the LEDs on the Aura.

Ready-To-Fly:
Solid Orange LED: Aura On and Calibrated
Solid Green LED: Aura receiving Valid receiver data
Possible Errors:
Flashing Orange LED: Aura Moved During Power Up
No Green LED: Aura NOT receiving receiver data
Connecting Battery and Arming ESC

1. Turn on the transmitter. Lower the throttle stick AND throttle trim to their lowest settings.
2. Ensure the aileron, elevator and rudder gimbals are centered.
3. With the airplane on a solid surface, connect the battery to the ESC and wait. The ESC will make the motor emit a series of audible tones during its initialization process.
4. The ESC will make the motor emit a short, final tone sequence indicating that the ESC is now armed and that the motor will spin in response to throttle stick movement.

ESC Throttle Calibration
In order to map the full range of the ESC output to your throttle stick motion you will have to preform an ESC throttle calibration.
NOTE: Execute ESC throttle calibration with the propeller and spinner removed.

1. Power on your transmitter, DISABLE any throttle hold or throttle kill switches, completely lower the throttle trim and set the stick to full throttle.
2. Connect the flight pack to your RV-8 60E G2.
3. Listen for the tones coming from the ESC through the motor, after about 2 seconds you should hear two tones.
4. Pull your throttle stick back to idle.
5. Listen for the ESC arming tones from the motor.
6. Unplug the flight battery to complete calibration.

Note: After throttle calibration is complete it is necessary to reset the failsafe (see your radio documentation, this may require a re-bind).
Final Radio Setup
Take this moment to finalize the position of the servo arms and pushrod lengths on your Elevators and Rudder and ensure that the motor is spinning in the correct direction (clockwise when viewed from the cockpit). Make any final control surface adjustments as necessary either mechanically or in the Aura, do not use trim or sub-trim.

Control Direction Test

Refer to the chart below to determine the proper control surface directions.
If controls are reversed, DO NOT REVERSE CONTROLS IN YOUR TRANSMITTER OR IN THE AURA CONFIG TOOL. Email us at support@flexinnovations.com for corrective action. Note that BOTH the Transmitter Control Direction Test AND the Flight Controller Sensor Direction Test MUST BE PASSED! IF EITHER ONE DOES NOT PASS, DO NOT FLY!
NOTE: There is pre-configured rudder to aileron and rudder to elevator mixing programmed into the Aura. Simultaneous movement of these control surfaces with rudder input is intentional and completely NORMAL. Additionally: Aura has a built-in flap system that moves the flaps at a slower speed. There is also flap to elevator mixing configured in the Aura Flap System. This speed and mixing is intentional and completely NORMAL.       Aura Sensor Direction Test
Perform a test of the gyro system to verify the corrections made for a given movement are correct. If any of the tests do not result in the correct reaction from the airplane’s gyro system, DO NOT FLY THE AIRPLANE, and contact us via email at support@flexinnovations.com
The flight control system activates with RF broadcast. Perform these tests in Flight Mode 3 (higher gain) for better visibility and then in the remaining Flight Modes. Control surface deflections are exaggerated in the pictures below for clarity. Please note that the control surfaces will move ONLY while the aircraft is being ROTATED.

Completion and Flight Readiness

Once your radio and Aura 8 configuration is complete there are only a few steps left to get your RV-8 60E G2 in the air:

1. Mount the propeller to the motor using the provided washer and nut.
2. Install the spinner to the prop adapter using the provided M3 X 10 screw.
3. Move the battery back and forth as necessary to achieve the desired CG (shown below).

Center of Gravity Verification
The center of gravity (CG) location for your aircraft is located in two locations depending on the flying style you wish to fly.
For general sport flying, the CG is located 11-7/32 inches (285mm) FORWARD of the trailing edge of the wing.
For more aerobatic capability, the CG is located 10-13/16 inches (275mm) FORWARD of the trailing edge of the wing.
First Flight and Quick Trim

We recommend that you fly the maiden flight using Flight
Mode 2. Trim the airplane until you achieve straight and level flight. Once you land execute the below Quick Trim procedure ensuring that you keep Flight Mode 2 selected.

1. Power off the RV-8 60E G2. Insert a bind plug into Aura Port S3 (you will need to remove the servo lead that is currently in S3). Check that the transmitter is powered on and re-power the Aura to enter Quick Trim.
2. Wait 5 seconds for the Aura to completely initialize. Confirm Quick Trim mode is active by checking the Blue LED is slowly flashing.
3. Remove the bind plug to save your trim settings, the Blue LED will now flash quickly indicating the new trim values have been stored successfully. Power off the RV-8 60E G2 and re-install the servo into port S3.
4. Center all control surface trims on the transmitter.
5. Re-power the RV-8 60E G2, the control surfaces should be unchanged as the new trims have been applied.

Enjoy your Flex Innovations RV-8 60E G2!
