I am installing a DLE 20 engine in a Great Planes Revolver. The throttle servo can either be mounted on top of the engine box or aft of the wing tube. CG won't be an issue in either case.

If I mount the servo aft of the wing tube I will have a fairly long pushrod to go from servo to throttle. I would prefer the shorter pushrod setup if the servo is mounted on top of the engine box.

However, I'm concerned that engine heat may effect the servo if mounted that close to the engine The servo would be about 4 inches behind the engine head and within the engine cowling.

Do you think the servo would be okay within the engine cowling or should I mount it aft the wing tube.

Thanks
