Unfortunately I haven't had the time to post much, but having said that, the basic platform is almost ready. I've mounted the motor, installed the servos, and am busy adjusting everything for correct CG.
Eventually (when they arrive) the flying wing will be carrying two 5000mAh 3S LiPo batteries from HobbyKing which will hopefully provide enough power for a decently long sustained flight. In the meantime, I've got my 3300mAh 3S LiPo hooked up, as well as weights, to balance out the plane.
I'd like to maiden it within the next few days, that's when all the little niggles will start coming out, and the tweaking begins.
