I finished the build! It looked alright, not the cleanest, but it's an A-4!
Then I maidened it...
Didn't go super well. I had my 2 1500mAh 4s's wedged as far back as possible, and it balanced a little nose heavy, but I gave it a shot anyway. Took off alright but I had to give it a lot of up-stick to keep it from nosing into the ground. by the time I got things situated the craft was a good ways off, and the sky is grey. First time flying in grey skies, you can't really distinguish dark clouds from foamboard...
Anyhow, ended up somersaulting hard. Made a little crater in the field. Looks like I have some major repairs to make.
