Just to follow up on this rather cool tutorial, I located a crappy little plastic geared hitec servo thats been sitting around in one of my tubs forever and decided to sacrafice it in the name of r/c.
After opening up the case I found the POT and motor were on handy little fly-leads, so I cut off the motor and just twisted the wires around the legs of a random LED I had in one of my many tubs of electronics-related stuff ( God bless tearing apart broken appliences ). I plugged it into the rx on the Gmaxx in place of a steering servo, turned it all on, centered the POT until the LED went out, then gave some steering input; hey-presto, works like a charm
Not sure quite what Im gonna power with this, maybe a lighting kit or seperate motor fan, or even a small buzzer/horn. I'll tidy up the wiring and shrinkwrap it fairly soon, just gotta get some wrap large enough.
Many thanks to BrianG for this idea, and all his other crazy little contraptions.
