Some days agos i was asking why the plane rolls 3 degrees to the right in AUTO1 mode
when in manual mode it was trimmed mechanically to fly perfectly straight.
Today i found some time and checked the Royal Evo's channel pwm.
Somehow the center of the aileron channel drifted (the tx settings were normal)
to 1520us and the elevator center slightly to 1494us.
All other channels remained the same.
In other words i trimmed the plane with tx aileron center at 1520us and in auto1 mode the center was set to 1500 (in the airframe file) thus i got a 20us worth of right roll
when transitioning from MANUAL to AUTO1.
