MMM V3 - First Run Opinions

[transtalon]

I actually was running a 25 tooth pinion when my MMM just stopped working.
But it was at least 7 minute of speed runs. I know that wasn't the cause of failure. I hooked up a fan on top of Neu 1515 1.5d and my motor does not get past 120 degrees at all. I am running a Poly RC 6k 25C lipo, this batts are awesome, lots of power and very good in retaining the voltage after a couple of months of not being use. To think about I paid 150.00 for a barely use pack from another forum.

i got my v3 on friday. had the same issues with the fan wires, shrink wrapped them and trimmed out the tab on the lower case that was interfering with the happiness of the little wires also moved the foam pad from under the fan plug to the center of the pcb. ran it friday night for about ten minutes, and again saturday for another ten minutes. running on 6s with a 1512 3d 15/46 timing zero punch control off brakes at 70%. opted to use the electric brakes this time with the v3. saves about 4 ounces. although if you use a 1515 the extra weight might be worth it ther worked extremely well with a couple of my v2's. the v3 performed very well. slow speeds were smooth and throttle control was very precise. tiny bit of cogging on startup when the car sits for a minute but goes away immediately. esc was never even warm to the touch, motor was about 90 and batts were cold. driving was high speed passes with street tires on a superb asphalt parking lot. with the current gearing it should see ~38, might try going to a 14 and see what happens. the only track i know of around here is smaller and 38 was too fast last time i was there. all in all castle has done a superb job refining this controller. i am glad to see a working unit (5th time is a charm) it was a long 10 months putting this project together but well worth it. i will post a video as soon as i can.

Slim, how did you weld your ESC and motor wires togheter?
If i take a close look on the shrink wrap, it is like if you have just touch the tips of the esc wire to the tips of the motor wire and melt the solder togheter
Me when i weld this wire togheter, i put lot of solder on the motor wire and lot of solder too on the esc wire and i place them one ON the other, squiz it with a pair of long nose pliers and melt the solder togheter.

Is your joint is solid????
