I bought a fan identical to this in MS at Nitro Toys and Hobbies. I think I paid under $10 for it and its is awesome. I don't know the # off hand, but if you search it should be easy to get. I wouldn't be surprised if they would ship it too for a few extra $$. The thing I like about this fan is it has a wide enough base to be servo taped on the chassis where ever I want with no heavy mounts etc. I have been running three in three different cars all powered off the esc posts without any failures after several months. FYI

Did you run the YR fan in for ~8 hours first ?

I have done so to all my YR fans, and they're still running perfectly.

I usually give them 8 hours at 4.8v, then clean the bearing, and re-lube.

Why would running them in help?

How are you guys running your fans directly to your battery? Just solder it right to the positive + negative? Arent there any voltage limits that need to be in place?

Thanks

Solder right to the + and - posts on the ESC, route the wires as required. Most of the fans listed will run just fine with full battery voltage. If it won't, it's not worth having.

I found that with the fan hooked up to the speedo terminals, when I accelerated the voltage drop across those terminals was so much that my fan stopped. So decided to give the fan its own power source, two tiny 150mah Lipo's hooked up in series to get the voltage. They have replaced some chassis weights so nothing lost there. Works spot on.
