As ugly as they are, I've decided to get another profile to help improve my 3D skills. Been flying a profile on AFPD and it's crazy the way that thing handles.

I've decided to get an OMP plane, due to their reputation, and they have ARFs. Got too many other projects to screw with building a kit right now.

I'm at high altitude, so the 46-50 size engines aren't going to give good performance on a 4-5 pound plane. I loose about 20% power up here. I need to know whats the biggest 2-stroke anyone has stuffed into one of the OMP ARFs. What mods, if any, did you have to do in order to get the motor in there?

I really wanted to use a TH .75. My favorite engine, but I don't think I can stuff it in there without doing major mods to the plane.

Whats the most powerfull engine that can be stuffed into these planes?

Thanks
