sticking a da 100 in a 50cc plane?

[DStJohn]

My son put a BME 95 in his 2.3M Comp ARF. He wanted to go with a BME 110 (which would have fit better), but we were worried about ground clearance. He has plenty of power now, even at 5000 ft + density alt.
We did not have any balance problems, actually the batteries are all the way forward against the motor dome. No need for weight in the tail.

A DA-85 on a 33% H-9 Cap at 21.5 lbs now I love this kind of deals. This kind of stuff reminds me of when I would show up at the field with a plane I had built. There would be epoxy all dried up and all over the place for the gluing of the wings, stab and fin. More experience flyers would ask me who put your kit together for you. I would smile like a pee cock and say "I did and the manual says it will take 25-30 hours and I did it in 12 hours. Now is that a priceless pic or what?" Now many years later I see the same thing round robin with the newer flyers, we all sit back and wait for them to take off to give us something to tell the flyers who are going to miss this excitement

It has been done, but with a DL.

Too much power is just enough. A big, well-designed twin should vibrate less than a single cylinder. Really, the immediate problem is balance, but that is easily overcome. I'd like to see this...
