Finally owner of a Rc Monster Slipperential

Spent maybe an hour with assembly, but need diff oil.

So what is the math behind figuring out what Weight oil to go with?

I have on hand: 2k, 5k, 7k, 10k, 30k.

Thank You RuuDxD

Even Castle did not know Power of 2200

Based on 120Amps:
2.84 ftlbs of Torque
Axle Torque 3.81
2.8 to 3.5HP
6S 25volts
Tire 4.8
Spur/Pinio Ratio 2.41:1
46Spur 19P
Theoretical Speed 78MPH
Calculated Motor Power 3024 watts (4.1HP)

At Under 11.5 lbs this would explain why the car from dead stop it Jumps straight up in the Air when Pull full throttle.

Trimmed down power, ran good.
car sat for couple yrs
Problem Now, throttle Stutters in begining, , give it a push and drives fine above 8mph. ??

No need to thank me, I just copied and pasted a link, thank BrianG, the maker of that site!

I could be wrong, but that could just be the sensorless motor trying to find the right coil.
It is called cogging, it looks somewhat like this:

He does run very little throttle in the video, so it is worse then when you accelerate faster.
It does get worse with heavy gearing if I am correct, so that might be something to?
If you run a lot on low speeds, or want a smoother power band, you might want to consider the new Sensored Castle Combo's?

I am not that knowledged in RC though, I am trying my best, so you might want to have this second checked :)
