Nice!
I am interested in the antenna on your car. You say its long. It's for 875 Mhz, Is it a full wave length or what?
If you do FPV on the ground, are you oaky with the range you get before failsafe?
I also like to take old parts and put them in to some new good use

[DocHardinger]

No should be 40mhz with Amplitude Modulation. And antenna is more than a meter long...so maybe its  a quarter wavelength long...i dont tested range for this tx but wifi range for this pi is about 150m without obstacles(you can get more if you dont use it in the EU and switch to 2.4ghz)...its enough for driving around ;-)

Oh yes now I see its 40 Mhz.
That should carry a long way even at surface use.
Thanks
