Early generation motorgliders put the engine up on the mast, and are
subject to vibration failures of components as a result.

There's a Silent IN on W&W under the 'glider' section. Very low hours
on the airframe, given the age of the ship. There are some "Silent 2"
gliders that were made with two-stroke engines, maybe a better choice
than the IN.
