Recently I purchased 4 Drift king 1/24 Scale vehicles hoping to try them out for a new track Idea! Sadly, All Cars would reAct to 1 single remote.
I found after removing old receiver board that 4 tripple AAA batteries (Stock Batteries) could power A 2.4ghz receiver at 6 v Aprx 6000 mah all I needed was two New 10A 280 motor (Esc) electronic speed controls from rcmart.com
One for the non-proportional steering rack & another Esc for the Throttle Control.
The Receiver is 3 channel with a pistol Remote.
I hooked both New Esc's to the Cars Original Batteries which contained a power switch in the wiring.
With both esc's Powered, I then tested the 280 Motors that move the steering and Acceleration! MAKING SURE OF CORRECT DIRECTION before Directly hardwiring Esc's to the two Motors. Once the wires were all connected all I had to do was plug each Esc into the correct channel for the remote. Assemble
Glad to say I Can Drift With a Buddy!

post pics. i have never heard converting from 27MhZ AM to 2.4gHz.

I actually cannot post images up on the forum yet. I believe it's because I had to start a new account and they do not allow images until so long etc.
Anyway I Realize I was not very thorough on the process I Did this in...So until I can return to Post Images (I'll go back and edit exactly how it was done).
