M7H

I did.

But if it was the ESC or the motor, which in return fried the ESC, I will never know.
After the ESC went, I replaced it for a new one, and it immediately broke after switching it on. Turned out to be a damaged sensor board in the motor.

After switching from 6S lipo to 4S, I never had a problem like that again, other problems occure then

As you can see in your first movie in where you drive together with some nitro 8th scale cars, you can see the big disadvantage of driving 6S lipo, mounted next to the car, it handles like crap. The weight is around 500grams more, and hanging on both sides of the car, giving the car to much roll....
My 4S 966e handles almost like his nitro powered bigger brother (I still believe nitro powered is the bigger brother )

But the problem with 4S lipo, is runtime. I have not yet been able to go flat out and reach 5 minutes.

Stories I read here about 8 minutes runtime, might be true on a small track, bur running at the MACH track, a real 8th scale track, like we have a lot in Europe, is a real challenge, atleast, if you also want to have some decent topspeed.....
