2.4 Flight Control Trim Adjustments
Condition(s):
1. Syma X5 with remote control bound
Standard(s):
1. Properly adjust yaw trim in order for Syma X5 to maintain
heading without control input
2. Properly adjust pitch (fore/aft) trim in order for Syma X5 to
maintain a stationary position without control input
3. Properly adjust roll (lateral) cyclic trim in order for Syma X5
to maintain a stationary position without control input
Crew Actions:
Pilot on the Controls:
1. Turn on the remote control power switch
2. Turn on the Syma X5 power switch
3. Announce “Clear on the Flight Line”
Visual Observer:
1. Assist Pilot on the Controls by confirming that no other
flight crew is attempting to bind a remote control to the
Syma X5 in use
2. Take a position perpindicular to the Pilot on the
Controls to assist in determining fore/aft drift
Procedure:
Adjust all trims (pitch, roll, and yaw) until a long tone is heard
indicating the trim is neutral. Apply throttle until the aircraft
becomes light on the landing gear. Note any tendency for the
aircraft to drift or yaw. Continue to apply throttle until the
aircraft breaks contact with the ground. If the aircraft begins to
drift, land immediately by lowering the throttle to the full-down
position to stop the rotors. Apply trim in the opposite direction
of drift. Apply throttle until the aircraft becomes light on the
landing gear. If all trims have been adjusted properly the aircraft
will not exhibit any tendency to drift. Continue to apply throttle
until the aircraft leaves the ground. The aircraft should ascend
vertically with minimal drift and no yaw. If any drift is present,
repeat this procedure.
