What's your motor data? I mean winding, magnets? I can check it out.
The belly hatch must extend to cover all the electronics and wires, but at the same time it needs to allow cooling air to go thorugh ESC and the battery. I had CC10 closed inside mini zagi wing, and it overheated (read: "smoked") at 8-9A. My 830 will be good for 10A al long as I cool them well.
As for the dimmensions the hatch should cover the stuff 2 ich wide (the same as the battery plywood support). I have a clean area between wing and the battery all the way along the wing chord (all my stuff is under the mounts) so between the mount and the bottom of the battery there is 7/8inch. The sidtance between the front of the battery and the tail servo is 5 inches. The battery is 3/4 inch behind the landing gear. See the picture for the explanation.
