I have available 69 and 75T spurs, and up to 35T pinions.
Anyone?

Start off with about 2-3 notches of timing past the large notch in the middle and start 1 tooth smaller on the pinion than the motor you were using before (if it was a 17.5). Most motors all will use the same gear within 1-2 teeth for off road.

I'm hoping Mikes has some Revtechs left tomorrow or Saturday. He had a ton of 17.5's on the 4th.

I will be down at Mikes for the Bigfoot, can't wait to run open up my ReVtech's down there. Our local track is tiny.

I really need some help with 13.5 wgt blinky. I have tried different rollouts and timing marks. I run on a small, not very technical carpet track. Any help appreciated. Does the bigger rotor help(12.5mm)

I put the HT rotor in my D3 and didn't like it. Felt too tight. The brakes came on way too strong even with them turned almost completely off. I think it works best in the 17.5's.

I have had good luck with my motor setup all season! I am running the purple ring rotor with the open end bell and ceramic bearings. I am running 4 clicks of timing and 4.0 fdr. I haven't tried the grey rotor at all. I am also running a 40mm x 40mm fan.

I just picked up a fresh rotor for one of my Revtechs... and the colored ring is pretty crooked on the magnet. There is a dollop of the balancing epoxy on the ring, so Im guessing it was actually balanced.

Without spinning the thing up it is hard to know whether or not it is truly balanced, though.

Has anyone received a rotor like this before?
