lets say you dont have alot of room in your touring car for electronics...as i have found in the T2............is it not a good idea to mount receiver on top of the steering servo?.........for other reasons than handling more like glitching...........

also what would be the smallest gage wire recommended for touring stock?

Well a servo has a motor in it so the back EMF and brush arcing (eg electrical noise) is what will be causing most of your problems. 27Mhz AM will be the most adversely affected. FM will be more resiliant and DSM is way beyond where the vast majority of the noise resides (DSM = 2400 MHz whereas most motor noise is below 300 MHz)

I think the coreless motors are less noisy so that may be another thing to consider. You could always use foil tape around the offending emitter (eg the servo) and connect the servo black wire (ground) to the foil. That will reduce the noise getting to the receiver.

I know the worst source of noise with my brushless motor setup is the ESC itself.

well im not having any problems yet as i have yet to install the receiver.....but trying to figure out weather i should buy a smaller receiver or mount it on top of servo or mabye just mount receiver that i have on edge...............so anyway what about the wire whats the smallest gage recommended?

I don't see much of a point in running anything thicker (smaller number) than 14 gauge, even though many people run 12 and 10 gauge.

Thicker wire will equate to a more efficient setup, but the difference is only theoretical.

Having said that, you're better off carrying around bigger heat sinks and heavier wire than more lead if your car is underweight, so I wouldn't bother swapping out thicker wire for skinney stuff in your touring car.

The bigger the wire the better its current carrying capability. I use the Deans wet noodle 12 gauge. I don't think I'd go smaller than 14 gauge though. 16 would probably work but its a little on the light side. Seeing some of the soldering around here I'd say the biggest issue is the solder joints for most stuff.

Don't forget most of the cars are under weight so you may as well use the 12 gauge....
