Heli Neu w/ Fan on ERBE?

[jpoprock]

I did a search and couldn't find a definitive answer. My question is, can you run a Neu 1515 2.5d Helicoptor motor (with fan), in a truck, like my ERBE or LST2 Conversion? With the MMM V3, and on 6s unless you suggest otherwise.

I think the can is a tad longer then a regular 1515 2.5d, and the pinion shaft will need cut down, but that's no big deal. I just want to know if this is a good or bad idea. I can't see how having a fan on the motor would be a BAD thing??

Granted, I'm gearing down to about 68/18, which should be ok running on 6s w/ my big Moabs. yes no?

Thanks!
