MMM V3 - First Run Opinions

We had to add a transistor to allow the processor to control the fan -- but the temperature at which the fan turns on is controlled directly by software.

It is set at about 150 degrees F, which is about 65C. The hardware is good to about 120C, so the fan comes on WAY before the temperature limits on the controller are hit.

120C What temp does the MMM shutdown? (if it has that option)

It shuts down at around 120C. If it does shut down, it waits until the internal temp drops below 70C before it will rearm.

I received my MMM V3 yesterday. I am running a Hyper 7 buggy with a 4S Poly rc 6K and a 20 tooth pinion. I ran it on two charges already and it seem
like it's working out real nice. The Hyper 7 is so stable at high speed and handles pretty good also, doesn't even flip over unless it goes in the grass and slid. I am pretty happy so far, I am also using the internal BEC from MMM.
Do you think the ESC can handle a 25 tooth pinion for more topend. I'm running a Neu 1515 1.5 D and it is a monster for it's size. Thanks for trying to please your customers Castle and any comment on the pinion gear will be nice. I don't wanna burnup my MMM, so any comment will be appreciated. Thanks again Castle Creation for doing the right thing.
