I've been having some problems intermittently with RF interference when flying my Nexstar EP. I always thought it was just some local interference which kicked on and off for whatever reason and that I needed to just do a range test before each flight.
However, just today I decided to try a range test with & without Ardupilot installed. With Ardupilot I could only go about 200 feet away before i started getting pretty significant twitching of the servos. Without Ardupilot everything was still rock solid at 200+ feet. So it looks like the jumble of wires I had inside before won't work... are there any special precautions I can take besides just organizing wires and keeping Ardupilot as far from the receiver as possible? Is it important to keep Ardupilot away from the ESC as well? Does anyone have any home-made RF shield ideas?
I also want to thank Chris & Jordi for making Ardupilot - not only a great autopilot but a really great place for beginners to start learning.
