Airframe Assembly Prior to beginning assembly, inspect all of the foam parts. Using a hobby knife or sandpaper, remove any excess flash or rough edges. NOTICE: When using cyanoacrylate (CA) adhesive to join or repair the airframe, DO NOT allow the adhesive to contact or get close to the fpv camera lens. The vapors from the adhesive will permanently fog the camera lens. Install the Spar 1. Slide the wing spar through the center section until it is centered.
Transmitter Setup Program Your Transmitter 1. Start with a clean model memory slot. 2. Set the model type to “Airplane.” 3. Assign channel 5 (Gear) to a 3-position switch. In the table at left, switch B is used. 4. Leave all other settings at the default values. Switch B will now control the flight mode function.
Control Surface Centering and Throws NOTICE: Remove the propeller from the motor shaft during control surface adjustments. Any movement of the throttle (even accidental) will cause the propeller to spin. With the receiver powered on, center the controls and trims. When the controls are neutral, the outer tip of the elevons should align with the trailing edge of the winglets, as shown in the illustration.
Balance the Airframe NOTICE: DO NOT omit this step. Failure to balance the airframe properly will make the aircraft uncontrolable and will cause a crash. Crash damage is not covered under warranty. The recommended center of gravity is indicated on the bottom of the airframe by two molded-in marks just behind the wing lock access holes. 1. Using two fingers, balance the airframe on the molded-in marks. 2. Adjust the position of the battery forward or backward to achieve proper balance.
Low Voltage Cutoff (LVC) Repairs 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.
Focusing the FPV Camera FP O To focus your FPV camera: 1. Remove the propeller. 2. Tape the provided focus pattern page to a wall. 3. Place your camera 8-10 feet (2.5-3m) from the wall, pointing at the focus pattern page. 4. Power on your transmitter, fpv monitor or headset and aircraft. 5. Center the image of the focus pattern on your screen. 6. Loosen the focus locking ring on the FPV camera. 7.
AS3X Troubleshooting Guide Problem Possible Cause Oscillation in flight Inconsistent flight performance Incorrect response to the AS3X Control Direction Test Solution Damaged propeller Propeller out of balance Motor vibration Loose receiver Loose aircraft controls Worn parts Irregular servo movement Too high of gain value in AR636 Trim is not at neutral Sub-Trim is not at neutral Aircraft was not kept immobile for 5 seconds after battery connection.
Problem Possible Cause ESC uses default soft Low Voltage Cutoff (LVC) Weather conditions might be too cold Battery is old, worn out, or damaged Battery C rating might be too small Solution Recharge flight battery or replace battery that is no longer performing Postpone flight until weather is warmer Replace battery Use recommended battery Horizontal lines in the headset display Digital interference on the selected channel Choose a cleaner channel Static or “snow” in the FPV feed The aircraft has reac
