Best motor fan for 1/10 buggy?

[jph]

Hi,

I'm after recommendations for a good quality motor fan for use in my Cougar KC.

I've killed 2 recently, one an unknown brand and the other branded as muchmore, both of which have been killed by (I presume) the heavy landings from jumps at my indoor club.

I have been using a mount that clips around the motor can but I think that allows too much movement during an impact so I'm planning on taping the fan directly to the chassis from now on.

So far I've been using 40mm fans but switching to a 30mm fan would be fine. I'm powering from a spare receiver port but could connect to the battery direct if necessary.

Thanks in advance
