I recently sold a 35% Extra to a guy with a ZDZ-80. He asked if I thought it would be enough engine, I told him I thought it was marginal for 3D but OK for IMAC style flying.

He called me back to tell me he loves the plane and the engine worked out great. What do I know!

The Red Bull Sukhoi is a little lighter than the Extra, so depending on your flying style it may work out great.

And BTW before you sell your plane you should be aware that I am out of the 87" Sukhois completely, but I have the Red Bulls and I will do a good deal one that plane.
