It is 4x4, by pressure I mean like going through long grass and up hills. The gears are fine checked these the upgrade was recent about 15 runs ago. I hope this helpedPressure? Torque applied by the motor? Can you provide a bit more information? 2wd, 4wd, how long ago was the brushless upgrade done?
is this the first run after the upgrade?
The crunching sound you state, sounds like it could be a stripped gear, are the pinion gear and spur gear meshed properly?, any signs of wear on them? Could be a plastic gear internally to the gear box as well.
Yes this is my first sensorless brushless motor. It does it whenever you get to something that is difficult to get through like long grass (like in the video). It also does it when you accelerate really quickly.
Sounds like cogging to me the motor you are using is underpowered and/or over geared. Too much load on the motor on initial acceleration but once it gets moving it's probably fine. I believe stock pinion is 12t dop down to a 9 or 10t pinion and see what happens.
I would not use a F540 (finned 540) motor and get a full 3650 size motor or even a 3660 motor. Depending on the kv or turn you get it maybe a little slower but won't cog as bad or any at all and run cooler.
What do you guys think about these motors?

It's a waterproof 540 that doesn't have fins. I know it's from China but I don't mind waiting.
So do you expect that the 4300kv would not have cogging problems anymore?
I'm not sure these cars are supposed to go through long grass...(at least the 2wd torment)It is 4x4, by pressure I mean like going through long grass and up hills. The gears are fine checked these the upgrade was recent about 15 runs ago. I hope this helped
