I'll try shortening the motor wires first, that might do it. If no luck, I'll stick a photo up for your opinions. The capacitor idea sounds interesting, which socket would I plug it into in the receiver? The one marked 'B' I assume, or have I missed the point

?
I really don't want to have to buy 2.4 GHz gear. On that subject, do you know whether you can buy Ghz modules to fit into the KO Esprit Vantage II stick transmitter?
Cheers guys
