Was it the Silent2? This is a really cool electric sailplane with a very innovative FES (Front Electric Sustainer) system. Far less moving parts and complexity than traditional boom mounted motor gliders.

The Antares is an amazing machine in virtually every way, but its also expensive and fairly full on (250k+).
The Silent is well under 100k new, I think...
Hope you find what your looking for.
