It is important to keep the compass away from current carrying wires, steel and other ferrous metals, compasses or other magnets, and especially the motor itself since it has magnets and is usually made of steel.
Sean, the best separation I can get if I put everything into the same box is around 16cm, see pictures here:

I really want to try it, and am going to order the hardware from you shortly to start building it unless you think this is a extremely bad idea and that that I should go for 2 separate boxes.
From looking at the pictures on the Wiki it seems to me both the Tinypilot and the motor controller are small and modular enough in design that I should be able to keep the ESC and the IMU at least 16cm away from each other. I essentially plan to keep the IMU in the upper left corner in the picture, and the ESC in the lower right. That should keep the power cables as short as possible, and the drivers as far away as possible from the IMU.
This evidently is enough in the old Autohelm 2000 design, so I hope it will be enough for Pypilot?
I will keep the power supply outside the box though, and just have a 5v outlet in the cockpit dedicated to Pypilot. The power supply can sit behind the outlet panel where where I have lots of space.
