When putting together the RC8.2e I guessed at what pinion gear to buy. My guess turned out to be a darn good one (for me anyway). I wasn't worried about speed. Anything in the 20 ~ 30 mph zone I'm happy with.
I'm running a 13T pinion gear at the moment (and stock 46T spur), with a Castle 4268 sized motor; I have maybe 1˝mm of a gap between the motor and the chassis brace. With the gear mesh set just right, I also found out that I'm maxed out on the motor mount. I don't even think I could squeeze any more room for a 12T pinion. This is great for me as I was looking to get a bit more torque out of the 2650kv motor while running on 3S LiPo packs.
Curious to see some actual top speed results from Garmin here in the next 24 hours...after taking care of double sided tape issue with some E6000 curing time
. I just have to know what my actually speeds are since my speeds that I'm obtaining are already to my liking with the Castle motor, 3S, and low gearing
