rjschaefer,

Go with the FS .91 and you will be happy. Mine flew with a MDS .68 and it was adiquate at best but Fastfly is right, this thing flies like a trainer in some respects just don't flip it over or make heavy bank turns until you are sure you've got the hang of it. Mine turns like a truck and I love it!!!! I had the engine quite about 5 times because I did not set it up right and I slightly damaged the plane due to a few rough dead stick landings. Make sure your engine is running right before you put this one up.

Fastsky, I'm going with the Saito .82 because I want the thing to fly like a truck and look like it will fall out of the sky. What about Proulxlaw using a YS 110, I'll bet the thing went straight up as fast as the real ones came down with all that power.
