You can drop the voltage to the fan by installing a small diode in line (the voltage will drop about .7v). You install it on one lead not across the + and - leads. If you put it in backwards, the fan won't run at all (the band on the diode ashould face the negative on the battery).

The 5v fans should be ok at 7 volts though.

I got the Reedy fan it it worked O kay, but the fins broke real easy. Also, it worked on my Yok CGM cause the motor runs forward, but on my BC the motor is mounted sideways so the heatsinks go sideways. Anyone know if it should still work or if they make a fan with the heatsinks going the otherway. On my Losi XXXS G+ the motor is sideways too.

I just purchased this as I am looking to cool down my Quad Mag motor and get better brush wear.

So far what are you guys doing as far as when you want to mount a personal transponder as well as run the fan? does anyone have picks of what they did to run both?

If I remember right, I ran the fan on channel 3 and the transponder on the batt spot or vice versa.

Hmm. Ok, I can't remember the setup of my MX-3 right now but I believe it does have a 3rd channel as well as a battery channel too.

So you can run the transponder off of the battery channel? interesting.

Yes you can. It is for stuff that needs power, but doesn't need a seperate channel for control. Since you don't need to control your transponder from your transmitter, it should be fine.

Problem with reedy motor heatsink. It don't clip on motor very good. Specially, Epic stock motors went running on a XXX-S. It even doesn't clip on motors with full can well either. I had to rotate heatsink until it stays on motor.
Can anyone post where I can buy these small fans off the internet? I have a idea. I going make a mount on motor. to run one. Thanks.

Racer- just get the Trinity car stand with fan, the fan is about 1.75 by 1.75 by .5 and is 5 volts. You get a new stand and the fan you need for like 10 bucks.

A diode? Do you mean resistor....? A diode acts like a one way valve, a pressure sensitive valve. Most diodes have a breakdown voltage of .7-.9 volts. Is that where your getting that figure? If putting a diode across the + - of the fan reduces the voltage to the fan, than what are we DOING by putting a diode on mod motors???

I have been using this fan, and it works GREAT. Drops motor temp from 256 to 130. Rated 4-8v so I run it on batt. direct, no problem. OD2510-05HB. Good CFM too.
