Finally got everything sorted today.
As you know, I'm new to this, even so......
Switched on the car and transmitter and applied throttle. Naff all, so tried again; still naff all.
Much swearing and checking of connections, tried again, but still naff all.
WTF? And then it suddenly took off at warp speed and nearly got me in the crown jewels. It took me a few minutes to work out that the transmitter was not operating in reverse, so when I pulled the trigger towards me it was actually braking. When the car took off it was because I'd pushed the trigger forward, thinking that it was either reverse of brakes.
Anyway, works now, but by 'eck did it make me jump when it suddenly decided to do a "ghost car" on me
