Do you have an idea how I can measure the speed of a model car (converted reely rhino 2) and can send me directly while driving on my phone or my laptop?

Hmm… With us were such boards, which show the speed when passing through. My RC car was detected and it showed about 53 km / h.

Sure, if you have a remote control with telemetry, you can use appropriate components (GPS receiver) to send the speed to the remote control

Do I need an extra receiver?

Some schools have speedometers, or you use the formula v = s / t (speed in m / s = distance in m / time in seconds)
