Seams to me folks are putting the 480 in the Airloils planes. You, like me, are going through the electric catch 22's. You need a bigger motor, then your batteries will be getting hot, so you need bigger batteries, then you need a bigger plane to carry the weight, and so on and so on. Thought I had it figured out with a Hacker A30-22s in a GP Reactor, power seamed perfect it floats super slow but I ran out of mixes in my 7c Fasst radio to make it fly straight. Next stop is a PA Extra but I'm not listening to the experts-er folks selling that 380 Watt motor as a long term power plant. Instead I'm going a size up to a Hacker 500 watt motor.
Electrics might be like the gas planes, anything below 50cc size just doesn't have an engine that has power to weight for comfortable 3D. With electrics it's like the foamies are mated perfect then there's a jump up to the 48ish wingspan planes as long as you stay around 35oz.
