I built a TR260 French Acrobatic plane about 4 years ago. The fuselage, wing and the tail feathers were all built and I fell ill. It is a 66" WS and calls for a .65 SAITO 4 stroke. Local HS claims that I can use a .45 - 60 2 stoke.
My question is this - is it possible to OVERPOWER a plane.
I have a .61cc ROSSI DF, that was bored out by the MFG to .81 and it has a TUNED PIPE. The way the plane is designed, I'd have to install the ROSSI upside down and run the pipe down the bottom. "DF" is for DUCTED FAN.
The ROSSI motor normally runs at about 27K RPM - and is it ever LOUD! ouch!
As an after thought, I think I might need a way to utilize a HOT-PLUG. I think the entire motor head is enclosed.
If that won't work, I'll just put an EVOLUTION .60 on it.

IMO that would be a terrible engine for that airplane. It was designed to make it's power at a very high RPM. To get to that RPM you would have to run a 10X9 or so prop. That prop is not going to work on that airplane. You would be much better off with a .91 4 stroke
