IMPORTANT NOTE: after the connection of the battery pack, do not touch the
plane for at least 10 seconds, because the gyro need this time to set himself, when it
is ready, a red light will be ON steady.
Use the sub-trim to center the thrust rudder servo (the two vektors, from top view,
need to be 5° open each) and if needed, adjust mechanically the two rudder servo
linkages, to center them.
NOTE: the rudder & thrust-rudder servos work always together on channel
RUDDER in every flying mode.
