Hi guys, my question is a combination of motor and b44.2.

What gearing (pinion and spur) are common for the b44.2? What about for a 7.5 turn reedy motor?

Currently am running the 81 (stock spur)/21 and at 20 degrees timing, I ranged 160-170 degrees.

Dropped to 10 degrees timing and was in 170-180.

Dropped to 0 degrees timing and hit 200 degrees >_<

I decided to put in a fan and I dropped back to 170 ish.

I ran another 2-3 packs and I was ranging from 120-130 and 150-160. I found this odd, but wasn't sure if my gearing was off? slipper? etc?

Thanks for any help.
