4s Motor and pinion?
 

Who is running 4s with a VFD? What motor, KV, and pinion are you running? I have a ton of small 4s batteries for my drones, it would be nice to take advantage of them...

I can't recall exactly, but I think I'm using a 13t pinion on the stock spur with a HH 3500 Puller Pro in my Ultra. I'll mainly use it on 3S but occasionally use it with a Helios 4S 1500 mah pack.

I've got a 4S brushed setup, 20T HH Magnum motor. Its been a while since I set this up but I think I settled on a 60T spur and a 12-14T pinion.

I designed a new spur gear cover that provides space for a up to a 66T spur gear.

I have a Puller Pro 2700kv with an 11T pinion that I run on both 3S and 4S.

Mamba max and quicrun 2700KV @3s.
Wonder if the motor will hold up to 4s. Anyone tried?
On the other hand, 3s is fine for my driving

I felt the stock 15T pinion was too much, even with a "slow" motor, so I'm geared down pretty low on my VS4-10 Pro:

Castle Mamba X and 1900 kV Slate motor with 11T pinion, 4S.

Has tons of torque and can still go plenty fast enough for a crawler.
