Hi Orlando,

Here is a rough guess of what you might have on your Dragon.

Flap length: 30 cm
Flap average chord: 10 cm
Control horn length from the rotation axis of the control to the link axis: 2 cm
Mid deflection in degrees ( I know that full is 85 degrees ): 25 degrees
Distance from the servo rotation axis to the flap rotation axis: 9 cm
Distance from the servo rotation axis to wing chord: 1 cm


Please confirm that the geometry is correct ( the diagram in the middle ) and send me the data requested above. You'll then have something close to the real case...



The JR 8611A is a great servo that has never deceived me. I have used it for about 7 years in most of my jets applications. I have never seen any of these servos burning. So something must be seriously wrong here.
