The story behind the build

Well, it' a R/C car and it ain't got rotors...but the wheels come close on full speed.
I just want to share the idea of using FPV equipment for funny other things, like a FPV-RC-car.
And here is how it looks to sit inside a RC car...

Choice of components

I already had this Traxxas Sledge and a redundant DJI FPV system, so let's combine them.

Building

The biggest problem was the position of the camera. I definitively wanted to place it inside the car to do all the bashing this car is capable for, without killing the FPV equipment. I guess, the roof of the car was designed "chopped" for optical reasons and normally it doesn't matter at all, but in this case it is root of a problem to get an usable feld of view. So I tried my best to place the camera as high as possible. The result is not perfect, but you can drive FPV!
Due the lack of a 3D printer I made the adapter of aluminum, added a heatsink and a small fan, that's it more or less.
First I installed a bigger fan, but it turned out as a bad idea to have the fan standing over the mounting plate (got crushed in a hard roof landing).
The second attempt with a 25 mm fan worked better and the cooling power still is more than enough.
For the power supply I already installed a BEC with 7.4 V for the servo, which is powerfull enough to also supply the airunit.
I used a 1 mm thick sheet of polycarbonate for the windshield and fixed it with hotmelt.

Driving quality

The field of view is not perfect, but with a little training it's definitively possible to drive this car FPV. In rough terrain with jumps ist's hard not to loose the orientation but after some training it's getting better and I'm pretty satisfied with this upgrade.
