transmitter &receiver
 

hello,
i have a ride on car that i want to change transmitter and receiver to extend the range to 400 feet or more.what equipment would i need to do this?

I think just about any 2.4ghz radio will accomplish this. You want to check out radios like futaba they are a good brand never have I ever have an issue with that brand.

Hello guys!

I have a TX JR 10X 72MGH in a very good condition. I want to install a module to transform it in 2.4GHX. I apprecite any advise how to do it, which module brand is available and what model/reference # should I start to procure in the market.

Very nice radio, no one answered your question all this time.
very easy, open up the box with take longer. Have to read the instructions, or just YouTube it like me.
To the Amazon or Evil Bay.
Look for frsky JR module , find a basic Frsky receiver. You pay a bit more on this.
remove the 72MHz RF module at the back of the radio, push in the new module, none.
cheaper one will be corona 2.4GHz module with receiver. Just change it over like a 8 tracks tape.
the crazy one , jp4 in 1 multi-protocol rf module with a lot of stuff sticking out, receiver type selector knob.
no Plug & Play . More reading.
but it will work on a lot of different type of receiver. (Read alphabet soup)
is like the old days JR will work with Futaba pcm receiver..
