During your rst ight, trim the aircraft for level ight in AS3X mode, at 3/4 throttle
with aps up. Make small trim adjustments with your transmitter’s trim switches to
straighten the aircraft’s ight 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 ight performance.
In Flight Trimming
3 Seconds
Post Flight
1. Disconnect the ight battery from the ESC (Required for safety and battery life).
2. Power OFF the transmitter.
3. Remove the ight battery from the aircraft.
4. Recharge the ight battery.
5. Repair or replace all damaged parts.
6. Store the ight battery apart from the aircraft and monitor the battery charge.
7. Make note of the ight conditions and ight plan results, planning for future ights.
Troubleshooting Guide AS3X
Problem Possible Cause Solution
Oscillation
Damaged propeller or spinner Replace propeller or spinner
Imbalanced propeller Balance the propeller
Motor vibration Replace parts or correctly align all parts and tighten fasteners as needed
Loose receiver Align and secure receiver in fuselage
Loose aircraft controls Tighten or otherwise secure parts (servo, arm, linkage, horn and control surface)
Worn parts Replace worn parts (especially propeller, spinner or servo)
Irregular servo movement Replace servo
Inconsistent ight
performance
Trim is not at neutral If you adjust trim more than 8 clicks, adjust the clevis to remove trim
Sub-Trim is not at neutral No Sub-Trim is allowed. Adjust the servo linkage
Aircraft was not kept immobile for 5
seconds after battery connection
With the throttle stick in lowest position. Disconnect battery, then reconnect battery and
keep the aircraft still for 5 seconds
Incorrect response to the AS3X
Control Response Test
Incorrect direction settings in the receiver,
which can cause a crash
DO NOT y. Correct the direction settings (refer to the receiver manual), then y
Motor Service
CAUTION: Always disconnect the ight battery before performing
motor service.
Disassembly
1. Remove the spinner nut by using a small screwdriver or hex wrench.
2. Remove the propeller.
3. Remove the four screws from the front of the cowling and remove the
dummy radial engine 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, the aircraft may vibrate, causing
the stabilization system to not operate correctly and/or decrease the life
of the servos.
