View Full Version : Gearing in a B4?

Hi,

I had a 6.5 brushless set-up in a B44.1 last week. I've now dropped that whole set-up into a B4 with an 81t gear.

The 6.5 in the B44.1 was FAST !! But in the B4 it is much slower, even with a few extra teeth on the motor pinion.

I was not expecting this, I expected the 2WD to be mental, almost uncontrollable !

Is the internal gearing so much DIFFERENT IN THE b4 ? It must be??

Not that I need the B4 to be stupid fast like the B44.1, but can it be geared so ? and if yes, what gears would I need?

Thanks.
