EN SAFE® Select Technology The BNF Basic version of this airplane includes SAFE Select technology which can offer an extra level of protection in flight. Use the following instructions to make the SAFE Select system active and assign it to a switch. When enabled, SAFE Select prevents the airplane from banking or pitching past predetermined limits, and automatic self-leveling keeps the airplane flying in a straight and level attitude when the aileron, elevator and rudder sticks are at neutral.
EN WARNING: Assemble the aircraft, program your radio control system, bind the aircraft, and verify correct operation before installing the propeller. Never attempt to program the radio components, assemble the aircraft or perform maintenance of any kind without removing the propeller or engaging throttle cut. Serious injury could result if the motor starts inadvertently with the propeller still attached. Model Assembly Horizontal Stabilizer Installation 1.

The included Y-harnesses have a yellow signal wire which connects to the white wire on the servo lead. • Flaps: Y-harness (Pack A) connects the flap servo plugs in center of wing with the receiver. • Ailerons: Y-harness (Pack A) connects the aileron servo plugs in center of wing with the receiver.
EN Connect the Pushrods to the Control Surfaces 1. 2. 3. 4. Control Horn and Servo Arm Settings The table to the right shows the factory settings for the control horns and servo arms. Fly the aircraft at factory settings before making changes. NOTICE: If control throws are changed from the factory settings, the AR631 gain values may need to be adjusted. Refer to the Spektrum AR631 manual for adjustment of gain values.
EN 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.
EN 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. 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.
EN Battery Installation and ESC Arming The Spektrum™ Smart 2200mAh 4S 30C Li-Po battery (SPMX22004S30) is recommended for best performance. 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 pack to fit in the fuselage. Be sure the model balances at the recommended CG before flying. WARNING: Always keep hands away from the propeller.
EN 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. 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.
EN Propeller Installation WARNING: Do not install the propeller until the aircraft has been completely assembled, all the systems have been checked thoroughly and you are located at a suitable flying site. WARNING: Never install a cracked, nicked or otherwise damaged propeller. NOTICE: If the propeller is not balanced, the aircraft may vibrate, causing the stabilization system to not operate correctly and/or decrease the life of the servos. 1.
EN In Flight Trimming During your first flight, trim the aircraft for level flight at 3/4 throttle with flaps up. Make small trim adjustments with your transmitter’s trim switches to straighten the aircraft’s flight path. After adjusting the 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. 3 Seconds Post Flight 1. 2. 3. 4.
EN Troubleshooting Guide Problem Aircraft will not respond to throttle but responds to other controls Extra propeller noise or extra vibration Reduced flight time or aircraft underpowered Possible Cause Throttle not at idle and/or throttle trim too high Throttle servo travel is lower than 100% Throttle channel is reversed Motor disconnected from ESC Damaged propeller and spinner, collet or motor Propeller is out of balance Prop nut is too loose Flight battery charge is low Propeller installed backwards F
