Problem
Possible Cause
Solution
Control surfaces not
at neutral position
when transmitter
controls are at neutral
Control surfaces may not have been
mechanically centered from factory
Center control surfaces mechanically by
adjusting the U-bends on control linkages
Aircraft was moved after the flight battery
was connected and before sensors
initialized
Disconnect and reconnect the flight battery
while keeping the aircraft still for 5 seconds
Model flies
inconsistently from
flight to flight
Trims are moved too far from neutral
position
Neutralize trims and mechanically adjust
linkages to center control surfaces
Controls oscillate in
flight (model rapidly
jumps or moves)
Propeller is unbalanced causing excessive
vibration
Remove propeller and rebalance or replace it
if damaged
Prop screw is too loose, causing vibration
Tighten the prop screw
