Hello,
In the DIY series, I built a Boxrover on the basis of a plastic food container, APM2.5 with GPS and telemetry, 2S Battery and a HK cheapo frame for the body (monster beatle, it comes with a 25 amps ESC and a brushless motor:
I removed the ugly HK cover to replace it with a plastic box. It is a nice soft plastic, resistant to shocks and easy to drill with a dremel like tool.
A small keychain HD camera is fixed with velcro. The box itself is fixed with dremellized holes, hot glue and a velcro band all around the frame.
One of the point to pay attention to is the parameters in the ardurover that govern the accelerations and speed. Indeed with thesse cheapo frame from HK, the spur gear is in nylon and can easily be shredded (like I did after the first ten minutes...buy replacement parts immediately)
I used version 2.42 of the ardurover firmware.
I tried a simple auto mission with one waypoint and that does not work well because the autopilot must probably calculate the trajectory based on B-splines (although I did not check the code) : instead of going in a straight line to the waypoint , it makes all sorts of arabesques.
However, as expected from bi-splines, when adding lots of waypoints, it goes all right.
I have a very bad video of my first auto Boxrover mission (sorry for the bad video quality, using a phone in the hands of my son, and he is not equipped with a brushless gimbal, yet :)

This is why you should go for a BoxTraxxas !
Nice work Hugues. Yes, rollover protection is very important!:-)
I am working on installing a PX4 in a Traxxas 1/16 rally car and finding enough room to mount all of the navigation components is doable, but difficult.
