This whole topic is very interesting. I did a little reading this year regarding making a small Reaper, just to fly within sight and at my local field. I thought it would be a new challenge though (tech wise) to see if I could program a few laps around the field for the plane to do itself (All within sight and with a Tx in my hand not FPV.) Anyway I discovered a tremendous amount of stuff that is out there for autopilots. Granted most of us here want anything but that and enjoy flying wheels up to touchdown, but the idea is still exciting to have this other control.

I had looked at some of these things http://store.3drobotics.com/t/parts/autopilots neat stuff. I am not sure about hese versus any Guardian, I suspect the EAgle Tree stuff is simpler to roll into our systems.


Sorry if this is a little off topic but I realized in some ways how lacking some of our reciever-electronics are with respect to these features.


Good luck with your project,
Dave
