1515 2200kv heat issues in buggy

[KniteWulfe]

I normally run no punch control but I tried 25%

Here are the graphs. Keep in mind that last huge voltage dip was in a chicane not on a straight. My LVC was set to 3.1 V/cell for this test. I also tried firmware 1.29 for this test and aside from maxing out at 138A instead of my usual 110-120 the results were the same as 1.24.

And the moment of shutdown including that huge drop in voltage:

I just thought of something. Those huge voltage drops coincide with glitches in my eagletree brushless rpm sensor which reads esc pulses. I'll post a graph with the rpm when I get home from work. I wonder if that could indicate an esc problem.

Here they are:

When the ESC died, same as the other zoomed graph.


RPM and V during a couple of the other glitches:

Something is not right there. Looks to me like you are using a 4s pack and getting over 50k revs from the motor.

16.8V * 2200kv = 36960rpm
