I will not be using an external BEC when my MMM gets here.... i dont know if the problems with the fan are solved, if the fan shortens, will the internal BEC work? if not i will probably do the "open case mod" and run it without a fan. Yesterday i was on a local track and there where 2 guys that had converted 1/8 buggys. Both of them had the MMM, both of them had done the "open case mod", none of them uses fan..... i felt on one of the controllers just after they had raced..... no problems whatsoever running without a fan..... i estimate that it was app 40-45 degrees centegrade. The car was a Xray XB8 EC with a Hacker motor (around 2400kv), MMM, 12/46 gearing, and 2S2P Orion platinum edition...... The way i see it is that using a fan in a MMM is only an extra source to problems..... BUT one have to keep in mind that you cannot "overgear" your car.... then there will be allot more heat.....

IMHO
