If I had to buy a ready made 4 channel transceiver module of 2.4 Ghz and use it for an rc toy that has servos that need PWM then how do I go about building the whole thing?
Do I need to make programming?
How to upload data that I have programmed into the Transceiver module?
Is the transceiver partly a micro controller, in which data can be stored?

If you need to get rid of the lag, you can use the capture-compare module on the PIC to measure the duty cycle of the PWM out of the receiver. You could just get rid of the low-pass filters then.
@oehrlein49 I actually got rid of the lag in a different way. I had a 500ms delay that would occur when going from forward to reverse so I decreased it to 50ms. Now the platform has no noticeable lag. I also removed the hard right and left turns that had the motors go in opposite directions. Now one motor goes to 0% duty cycle while the other goes 100%. I was told about the input capture by a co-worker and it sounds like it will be faster and allow for proportional control.

Nice work though!
