Here is my setup for my local track in South Africa.
Here we still runs foams in some classes (13.5 in this case) so my FDR and rollout is captured on the attached screenie.
Brand new Xerun 60.A Ver2.1 first time run on a track with a brand new HW sensor cable.

Car had awesome punch out of the corners and great speed down the straight.

Temps after 5 min run.
Motor = 55º-59º C
ESC = 35ºC
Ambient Temp = 25ºC

Google Earth link of the track included.



One problem.....
Intemittently during the race the car would go into safe/sensorless mode for a corner or two then recover on it's own.
This is one of the reasons why I tuned Voltage and Overheat protection off in trying to find what the problem is.

During the qualies, the car was very quick and while leading, on the last lap, the car would go into safe mode and stay that way for a corner or two and then recover on it's own.
For the mains, the car was fine during the warm up lap, at the start I pulled off and it went into safe mode right away, I then pulled over in front of a marshal and he switched the ESC off and back on again, the car then ran fine for the rest of the race.

What is causing the problem?

Thx.

Edit: I thought it may be the batteries, so I used them in my 10.5 car and it performed perfectly, I then put the 10.5 batteries into this car and it still went into safe mode.
Dnring the main,
