So, today I did some GPS testing. Here are the results:

10 GP3300 matched cells

18/84: 35.3 mph
20/84: 38.0 mph
22/84: 40.5 mph

9 GP3300 matched cells

18/84: 31.2 mph
20/84: 34.6 mph
22/84: 36.7 mph

8 GP3300 matched cells

18/84: 27.5 mph
20/84: 31.9 mph
22/84: 33.2 mph

The hottest my motor ever got was 115 F, and the hottest the controller ever got was 91.9 F (This was on 8 cells at 22/84).

What do I need to do to get to that 58mph you mentioned? Are these gear ratios correct?

18/84 = 12.69:1
20/84 = 11.42:1
22/84 = 10.39:1

I'm thinking that I'm gearing it way too low.

What do you all think?

Thanks ....
