Introduction

Arrows Hobby is adhering to the R&D concept of following no set form, which, after the success of trainers, warbirds, jets, once again challenges gliders. Its first glider, 2000mm SZD-54, has been tested and summarized by excellent domestic and foreign R&D engineers and senior testers in six rounds, and has been launched in the best posture.

To achieve the most dihedral, the SZD-54 was designed with a specialized two- piece CNC threaded metal spar joiner- allowing the aircraft to maintain its wing geometry during de-manding flight routines. Besides, the pre-embedded carbon fiber spars in fuselage
and main wings ensure overall rigidity in high-G maneuvers.

A high-quality 30A ESC paired with a 3136-KV1000 motor provides ample power with a 3S pack (1300mAh-2200mAh) to perform most aerobatic maneuvers. Positive and negative loops, stall turns, point rolls and inverted flight can be easily and excellently
performed.

The wing and horizontal stabilizers are designed with a snap-fit structure, which can be instal-led by pressing and detached by pulling. No screws or glue necessary! The most thoughtgul structure greatly facilitates transportation and storage. Under the premise of the degree of factory completion being up to 85%, the aircraft can be built in as little as 3 minutes!
Don’t settle for any less than the best- Arrows Hobby 2000mm SZD-54!

Linkage rod installation

1. With the elevator servo at its neutral position, connect the pushrod to the elevator.
   
   Note: connect both servo arm and servo horn the outer-most holes.

Wingtips installation

1. Install the wingtips onto the wings by sliding them aft.
   

Battery installation

1. Remove the battery hatch.
2. Remove the hook & loop tape from the fuselage.
3. Apply the looped surface to the battery.
4. Install the battery into the fuselage- securing it with the preinstalled battery straps.

Note: The weight of each battery may vary due to different manufacturing techniques. Move the battery ore or aft to achieve the optimal center of gravity.

Receiver diagram
The cables from the servo connector board should be connected to your receiver in the order shown. Note that the LEDs can be powered by any spare channel on the receiver.
Tuck the wire leads into the recessed cavity towards the rear of the battery hatch.

Preflight check

Important ESC and model information:

1. The ESC included with the model has a safe start. If the motor battery is connected to the ESC and the throttle stick is not in the low throttle or off position, the motor will not start until the throttle stick is moved to the low throttle or off position. Once the throttle stick is moved to the low throttle or off position, the motor will emit a series of beeps. Several be-eps with the same tune means the ESC has detected the cells of the battery. The count of the beeps equals the cells of the battery. The motor is now armed and will start when the throttle is moved.
2. The motor and ESC come pre-connected and the motor rotation should be correct. If for any reason the motor is rotating in the wrong direction, simply reverse two of the three motor wires to change the direction of rotation.
3. The motor has an optional brake setting. The ESC comes with brake switched off and we recommend that the model be flown with the brake off. However, the brake could be accidentally switched on if the motor battery is connected to the ESC while the throttle stick is set at full throttle. To switch the brake off, move the throttle stick to full throttle and plug in the motor battery. The motor will beep on time. Move the throttle stick to low throttle or the off position. The motor is ready to run and the brake will be switched off.
4. Battery Selection and Installation. We recommend the 3S 1300mAh-2200mAh Li-Po battery. If using another battery, the battery must be at least a 3S 1300mAh-2200mAh battery. Your battery should be approximately the same capacity, dimension and weight as the 3S 1300mAh-2200mAh Li-Po battery to fit the fuselage without changing the center of gravity significantly.

Transmitter and model setup
After assembly and prior to your first flight, make sure all control surfaces respond correctly to your transmitter by referring to the diagram below .

Control throws
The suggested control throw setting for the 2000mm SZD-54 are as follows (dual rate setting):

Tips: The maiden flight should always be flown using low rates, fly the aircraft until you are familiar with its characteristics prior to trying high rates. Make sure the aircraft is flying at a decent altitude and speed prior to using high rates, as the aircraft will be sensitive to control inputs with the larger control surface movements.

| High Rate| Low Rate
---|---|---
Elevator| 14mm up / down| 10mm up / down
Rudder| 16mm left / right| 12mm left / right
Aileron| 16mm up / down| 12mm up / down

Control horn and servo arm settings

1. The table shows the factory settings for the control horns and servo arms. Fly the aircraft at the factory settings before making changes.
2. After flying, you may adjust the linkage positions for the desired control response.

Finding the center of gravity
Finding the correct center of gravity is critical in ensuring that the aircraft performs in a stable and responsive manner. Please adjust the weight distribution so the aircraft balances in the range stated on the diagram.

• Depending on the capacity and weight of your chosen light batteries, move the battery forward or backward to adjust the center of gravity.
• If you cannot obtain the recommended CG by moving the battery to a suitable location, you can also install a counterweight to achieve correct CG. However, with the recommended battery size, a counterweight is not required. We recommend flying without unnecessary counterweight.

Before flying the model

Find a suitable flying site
Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be required and have mastered flying your plane in confined spaces, choose a site which is at least the size of two to three football fields – a flying field specifically for R/C planes is best.

Never fly near people – especially children, who can wander unpredictably.

Performing a range check
A radio range check should be performed prior to the first flight of the day. This test may assist you in detecting electronic problems that may lead to a loss of control- problems such as low transmitter batteries, defective or damaged radio components or radio interference. This usually requires an assistant and should be done at the flying site.
Always turn your transmitter on first. Install a fully charged battery in the battery bay, then connect it to the ESC. In this process, make sure that the throttle cut functionality is on, and that the throttle stick is secured in its lowest position- otherwise, the propeller/fan will engage and possibly cause bodily harm.

Note: Please refer to your transmitter manual that came with your radio control system to perform a ground range check. If the controls are not working correctly or if anything seems wrong, do not fly the model until you correct the problem. Make certain all the servo wires are securely connected to the receiver and the transmitter batteries have a good connection.

Monitor your flight time
Monitor and limit your flight time using a timer (such as a stopwatch or on the transmitter, if available). As modern Lithium Polymer batteries are not designed to discharge completely, when the battery runs low, the ESC will lower then completely cut the power to the motors to protect the battery. Often (but not always) power can be briefly restored after the motor cuts off by holding the throttle stick all the way down for a few seconds. To avoid an unexpected dead-stick landing on your first flight, set your timer to a conservative 4 minutes. When your alarm sounds you should land right away.

Flying course

Take off
Point the aircraft into the wind while slowly applying power until the aircraft starts to track straight, use the rudder when necessary. When the aircraft reaches takeoff speed, ease back on the elevator stick until the aircraft is climbing at a constant rate without decelerating. Climbing at too steep of an angle at the relatively low speeds of a takeoff-climb may result in an aerodynamic stall.

Flying
Always choose a wide-open space for flying your plane. It is ideal for you to fly at a sanctioned flying field. If you are not flying at an approved site always avoid flying near houses, trees, wires and buildings. You should also be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards, or soccer fields. Consult laws and ordinances before choosing a location to fly your aircraft. After takeoff, gain some altitude. Climb to a safe height before trying technical manoeuvres.

Landing
Land the aircraft when you start to feel sluggish motor response. If using a transmitter with a timer, set the timer so you have enough flight time to make several landing approaches. The model’s three point landing gear allows the model to land on hard surfaces. Align model directly into the wind and fly down to the ground. Fly the airplane down to the ground using
1/4-1/3 throttle to keep enough energy for proper flare. Before the model touches down, always fully decrease the throttle to avoid damaging the propeller or other components. The key to a great landing is to manage the power and elevator all the way to the ground and set down lightly on the main landing gear. With some practice, you will be able to set the aircraft gently on its main gear and hold it that way until the speed reduces enough where the nose wheel (tricycle landing gear aircraft) or tail wheel (tail draggers) settles onto the ground.

Maintenance
Repairs to the foam should be made with foam safe adhesives such as hot glue, foam safe CA, and 5min epoxy. When parts are not repairable, see the spare parts last for ordering by item number. Always check to make sure all screws on the aircraft are tightened. Pay special attention to make sure the spinner is firmly in place before every flight.
