Hey guys - I have a similar setup as above, but I plan on running nothing more than 14 cells nimhs (ib3800 and up). I also have the strobe slipper & sprong setup on its way. What motor & pinion do you think I should use? Mike recommended the 1940 6 or 7 turn with 18 51 gearing, but I'm concerned about the lack of pinion availability. Is there a motor that would work well with 14 51 gearing?
