power source for the esc fan?

12v off receiver may be a little weak. It will do really well if you connect directly to the batteries, but it may shorten the life of the fan. I am currently running two 5v off channel 3 and so far it has been perfect.

Good Luck Bro.

If you wanta quick and dirty way to reduce the voltage to the fan by a little (1 or 2 volts), then two or three diodes in series of the fan power lead will work. Each diode drops about 0.7v. Fans don't take much current, so standard RadioShack 1A diodes would do. That'll take the 14.4v down to 12 effectively.
