Back on topic ... it would be interesting to have such a forum. However, after having owned many EP planes, I find that its not worth it. As many have noticed EP planes are built light, the vibration from anything more than a 30 sized 2C motor will potentially cause fatigue on the fuse (be it the motor box, firewall or the fuse itself). Most are also built with a motor box so you need to dock that off to fit the motor. Then you have CG issues, the planes are built to balance fine on a light motor up front.
So to overcome the fragility of the EP planes you beef it up, that's more work and more weight. Best solution is to just covert the glow guys into the EP Cult.
Yeah ... let's have an EP-2-GP forum. Hehehehee ...
