I've seen some topics around this but non exactly on.

Can a hobby grade transmitter at 27mhz work with toy grade cars? What about toy grade transmitters with properly chipped transmitters?

from https://radiocontrol.fandom.com/wiki/List_of_RC_frequencies

Code: Select all

The 27 MHz band is legal in most, if not all, countries for use with all types of RCs. Subject to interference from adjacent CB Operation. Note:cheap toys seem to usually use Channel 4 if there is no channel stated.

    26.995 MHz -- Channel 1 -- Brown
    27.045 MHz -- Channel 2 -- Red
    27.095 MHz -- Channel 3 -- Orange
    27.145 MHz -- Channel 4 -- Yellow
    27.195 MHz -- Channel 5 -- Green
    27.255 MHz -- Channel 6 -- Blue - Shared with CB Radio Service, never an "exclusive" channel

I'm mostly curious about the Radio Shack/Tyco Cars, but I have 2 associated 27MHZ RTRs as well.

A quick amazon search shows crystal pairs available that match the channels

Many times, toy grade transmitters and receivers are programed different.

For instance, X-Mods. The crystals work with all 27mhz AM radios, but the transmitters aren't compatible with hobby grade receivers.

I've once driven a proportional Nikko (1:14 evolution series) with a hobby transmitter, and that went well. The other way around worked too.

Another try with a non proportional Nikko buggy and a hobby transmitter gave me OK throttle, but steering trim was waaaay out of range of the trim switches on the transmitter.

Do you recall if it was a Futaba keyed transmitter?
