hello friends,
I was working on an Arduino based RC transmitter based on a 433 MHz RF module. Using this module a PPM signal is transmitted and at receiving side, it is decoded by another Arduino.I tried to explain working and making of the transmitter so please have a look of it:



This transmitter has 4 channels but by applying some modification it can be increased to 8 or even more. This transmitter has the range of around 50m. And it can be made fewer than 600 Rs. Due to the smaller range, it can be used for park flyer or RC car which can be operated at this range.

Please suggest improvement if any for enhancing range.

Bro really amazing work

And congratulations for your success

And to improve range you can use nrf module range 1100 meters

Hopes this would be helpful

Great work buddy.
If you are using standard PPM, just plugin a FRSKY DIY module and you have a full range radio. With a little more effor, you can add telemetry or just use an existing IU like the FLD-02. See more details on the this build log:

That's a nice idea. I will go through communication methodology in nrf module and try to implement it.
