I think the Zero just wants to be lighter. I've been having my own frustrations too lately though, with electric powered micro planes. Got a decent flight out of the Edge, but no video since my flying buddy was away. Flew it in windy conditions with my buddy taking video, and I managed to lose it, possibly out of range. Basically no damage other than regluing the motor mount onto the balsa firewall, but then again you get more nervous with each flight and never try it again. I'll have to get you going with the 500 series electric rc thing again. Weight's no problem. They just have to be flown very carefully however.
