I want to use a rc transmitter and reciever set, that i salvaged from an rc airplane. I am building a tanks with tracks that i am using an arduino to control the motors. i want to use the rc trans/reciever to control the arduino, not just for motor control. Where do i start?

When do i start?
Now?
The rc airplane probably had servos that the receiver controller.
Does your tank have servos to be controlled, or do you want to add servoes to it?
Or do you want to sense the servo control pulses and take some action from there?
Or use servos as motors in the tank?
I want the arduino to detect the signal coming from the reciever, and the do something based on what channel the reciver is sending a signal on. the transmitter/reciever can control 5 servos, so it can send 5 seperate signals. I am thinking channels 1 left track, 2 right track
3 turn turrent, 4 light up LED, etc!
I currently use the arduino to control motors via hbridge. or transisters.
Question is: How do i get the arduino to detect the incoming signal from the reciever. the reciever outputs a PWM signal to the servo, so arduino must interpet it as PWM, not just a simple on/off (hi/lo) so that I can have proportional speed control of the tracks.
I guess i want to know how to get ARduino to read an incoming PWM signal, and haven't been able to google that successfully.
thanks

It's PPM, not PWM.
Have you tried pulseIn?
