Kraton Kraton 6s Pinion Gear

[Todd Packer]

Just picked up one. Anyone have any suggestions on gearing? Was thinking of putting in a 23T pinion.

I just want a little extra pop.

What electronics are you running? If stock, that’s waaaaaayyy too big of pinion.

Yeah it’s stock
What about an 18T on stock electronics?

6s or 4s?

I ran the 15T speed pinion without motor cooling and it was getting very toasty on 6S. With cooling now, I'm thinking I'll try a 16T.

It all depends on your driving, how much acceleration and braking you're doing, compared to, say, speed runs. Also grass vs asphalt will cause a lot more heating (even with the stock pinion).

Honestly though.. that thing is a freaking rocket with a 15T... I can't imagine needing much more, but maybe that's just me.

I would say a 16T is probably max on stock electronics without a fan. Maybe 18T if you have a good cooler.

16T seems to be my sweet spot (4s or 6s). Stock electrics. But using double fans at the motor and a HS fan at the stock ESC. 17T is nice with 4S. But not with 6S. Heat and all despite the fans. Perhaps in the cooler weather I will up it to 17T again. I run both 6S and 4S frequently in my Kraton. I'm good with 16T and the driveability.

6S and 20T (speed pinion) is the absolute max and you will cook the motor in 5 min.
23T will just burn it out.
You want to stay around 15-16T for bashing, 14T in grass. Add a fan and you can gear up 1 or 2 teeth.
In addition, higher pinion makes no sense as you will blow out the stock tires starting around 20T.

Yes! I blew up a stock tire on 15T! Gotta be careful when a front wheel comes off the ground in a spin and gets all the power.

Yes, you would want to change your diff oils. Stock is very loose and 1 lifted wheel will result in a foam explosion

i run 25t on a 4985 and my fronts balloon all the time. Never shredded a tire yet. If this guy runs a 23t hes gunna cook his electrics before he has a chance to shred a tire.

Oh, and that was with 1M centre. I think it was just bad luck

I smoked my esc on my notorious at 18 so i'd def stay down in the 15-16. Now i run a max6/4092 (either 1480 or 1730kv) hobbystar in all my 6s rigs with 24/46 gearing, and 12v fans for cooling. The 6s Outcast tires seem to work pretty well on the k6 as well. They will still balloon a little but prob a little stiffer than the stock k6 tires.
