We ended up choosing a different controller board and used 802.11 for the wireless interface.
Thanks. I am curious, I have seen projects on youtube that use 802.11. In order to do that, you need to have router on board the vehicle, no?

I think that your H-bridge might be too weak to get good acceleration, you’d better take the original H-bridge (the one originnaly in the RC car) and control it with the arduino.
Thanks for the advice. Unfortunately, when I examined the original circuit board I could not find an H-bridge!
I have attached a picture. Do you see an H-bridge on there? There is something on there with 10 pins on each side, is that it?
