Very good points. I'll make note of all of them when building my plane. I haven't had very many giant scale planes and I appreciate any points you guys can give. I've been flying 3D aerobatics for the past year now but most of the planes I've been flying were 1.80 size and under. I want something a little more stable and something better for IMAC competition. I think this Edge will do it for now until I find enough money stashed away for a 40% plane.

As for the comment on the ZDZ 80, I know that is a good engine and I've seen that engine on many 33% planes. It is an awesome performer to say the least but I am a fan of the twins and the fact they they have less overall vibration gives me a better excuse to buy one.

O.K. we've settled the issue of whether or not the BME is a good engine or not but which out of the ones I've listed has the best throttle response? Are they all pretty similar?

Thanks for your help guys!
