Cooling fan hookup?

[Nick]

Heres a picture of mine, it's a small 25x25mm Laptop fan (plugs into 4th reciever channel). It blows air onto the ESC and has a switch near the transmission, so I can have it on when it gets hot rather than just on all the time. :)

That looks like a winner - Thats basically the same as Mike and I have on ours - cept we keep ours on all the time - cause ya never know when some nitro knucklehead needs a good reality check. You wanna race out Emaxx with a nitro

I hooked it up to the BEC output wire and it seems to be ok.....although the speed control isn't hooked to the motor yet. Since this is the first time I powered up the system I noticed that the steering servo seems to pulse/twitch when no steering input is being given, even when the wheels are off the ground. I disconnected the fan and the twitch did not change. The shift servo does not do it. I have an Airtronics MX-3XS controller and reciever and an Airtronics ERG-VB high torque steering servo. Does anyone have any idea what this might be caused by? The BEC is all the way in the back of the truck as far away as possible. I tried moving it around with no affect. Radio interference maybe? I was inside by the entertainment center.

Is the antenna wire touching, or very close to any metal parts? If so you should try relocating it. Sometimes this can cause the twitching you described (I experienced this with my rustler). Usually, if you can just run it straight up through the body and not snake it around other components, it won't recieve any interference. Oh, is that a DIGITAL SERVO? I have a Futaba S9451 and it does twitch every so often, but, not enough to affect my control.
