I have an Illusion with a MVVS .77 rear exhaust and it flies solid as a rock , a very good
old school pattern ship, just too fast for the new patterns. The nose is very narrow and the
MVVS is a tight fit even though it's the same physical size as a .60 . With the MVVS .77 it has
absolutely unlimited vertical performance. Mine is a taildragger and I don't think there is
enough room in the nose for a retract nosewheel as the fuel tank and exhaust header take
up all available space. The engine is mounted inverted so if you wanted retracts it would
probably have to be mounted to the side. It's probably one of the best flying old style pattern
ships I have ever flown.

PS: Don't worry about the quality of MVVS engines, I think they are the best 2-strokes available
and lots of power.
