|  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... Lou |

| Re: 4s Motor and pinion?
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. https://www.thingiverse.com/thing:4030125 You can find my build thread here VS 4-S Build, Volt Up Gear Down |

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 |

| Re: 4s Motor and pinion?
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. |
