Default Power cut at full throttle

Hi everyone, I have Hobbywing Xerun Justock 10.5T Motor and ESC combo. These are permanently set to zero timing from factory. This is brushless sensored combo. I'am having issue of instant power cut at full throttle when running in sensored mode while in non-sensored mode it works fine. I'am running this in Tamiya TT-02. Any help would be appreciated. Thanks.

First to try is a new sensor wire and re calibrating the esc.

Make sure your sensor wire is plugged in all the way - sometimes they pull out a little bit from the ESC and you get intermittent response.

I found the solution. First I recaliberated the esc. Second I just needed to use 3s lipo battery in place of 2s lipo battery. Thanks for the help guys.

Sounds like the lipo cutoff is set too high. If you want to use the 2s battery check that the lipo cutoff is set to about 3.2 v/cell or as a 2 cell source whatever is appropriate for your esc.

Actually that's not the solution, It did however, expose the problem. Either your 2 cell battery is bad or the LiPO shut off is set incorrectly.

Could you post a link to the combo you purchased. We can help a a lot better if we know what ESC you are running.

A 10T motor is rather hot for that ESC. It's right on the edge of what it can be used for and should not be used on 3s. As said before, it could be your cutoff voltage or a bad / out of spec battery. It could also be a restriction in the drive train putting to much load on the motor / ECS. Brushless Motor Limit:
2S LiPo/4-6S NiMH: ≥8.5T (1/10 on-road), ≥11.5T (1/10 off-road)
3S LiPo/8-9S NiMH:≥13.5T (1/10 on-road), ≥17.5T (1/10 off-road)

Hmm,so this means I need a better 2s lipo. What C rating should I get?

Thanks for the Help
