I am flying my quad and have started planning a Hexa build for FPV, would appreciate some input on a couple of questions. Plans include powering the FPV gear with its own small Lipo battery, separate from the aircraft. A camera mount with 2 axis servo stabilization.
1. Mounting the Ardupilot? What are thoughts on mounting the flight computer on the anti-vibration mount (see the RangeVideo image), then velcro the whole mount to the frame? It would be nice to be able to move the flight computer among different frames, or even a fixed wing. Right now I have the APM 1.4, with an APM 2.0 on backorder.
2. Use of a specific BEC? Are there advantages of using a separate BEC for powering the Ardu (or camera servos)? Instead of using the BEC in an ESC. I seem to recall discussions about this, and how the ground path has to be set up right or nothing works. Just not sure on this one.
3. What is considered the minimal spacing between propeller tips? I want to size the arms such that the bird is an efficient flyer, but takes up no more room than necessary for transport.
Thanks very much,
