Found a link to info. on a WWII-era powered two-seat sailplane..
Frankfort Cinema 2
A unique twin engine arrangement: mounting on the struts!
This avoids a lot of problems with other installations: landing gear mods, CG shift, non-ideal thrust line, prop clearance issues, turbulence/interference with other surfaces..
The struts turned out to be more than strong enough to handle thrust loads in this old design.
It even had counter-rotating props to cancel torque.. probably not even necessary with such small engines.
Perhaps this concept is one worth reviving with modern construction & power options? :cheeky:
