[Paparazzi-devel] Reply to:" A couple more questions (Christophe De Wagter) and (Felix Ruess)"

Hi.
The plane is trimmed for level flight in MANUAL mode mechanically so 
when the servos are at center (1500 microseconds) the plane is flying 
perfectly straight without any rc transmitter trimming
so in AUTO1 it shouldn't be needed to add any ins roll correction if the 
imu is correctly installed (mechanically).
Now Felix said that the plane might not be level in straight flight and 
this can happen indeed
but i think this is not the case here, the PFD shows a plane rolled to 
the right by exactly 4 degrees which
is certainly wrong by looking at the plane while it flies.
I think that the culprit is the radio file settings, maybe the settings 
are wrong and when the tx aileron stick is at the center, the servo pwm 
might be different from the 1500us set in the airframe file.
It is also possible that the default center of the Multiplex Royal Evo 
is not 1500us, i will measure it tomorrow.
