Tonight's Dumb Idea...

[Wayne Galligan]

 I have the servo of my plane mounted directly behind the engine on the fuse but still in the exposed area of the engine heat and oil and it has survived well. 
 My only concern about mounting the servo to the mount with the engine would be all the excessive movement you would have on the wiring.  Take a piece of wire and bend it back and forth enough and you will get a failure pont.

  I gave this notion some thought a few years ago and even drew up an aluminum mount to position the servo close to the engine centerline so as to minimize the (vibratory) moment arm. (Behind the back cover, below the carb on a YS120.) With no way of knowing just what servo component might reach resonance or overheat, and expecting that the motor was most likely area for failure, I decide not to try it. I've since seen some servos where the wiring between the circuit board and the motor is a pretty stiff 3 strand wire that likely wouldn't like much vibration either. As some have done this with success, I probably over analyzed it. Go for it Bob, we're watching.
