Ok, back to the calculator...
If I go with a Great planes ammo motor at 3300KV, 9.6v (cutoff for my 3S pack) the higher diff ratio (2.83:1), 3.5" tires plus .2" ballooning,76-80 tooth spurs with 16-26 pinions. I get a range from 25.9 to 44.4 mph with a motor rpm of 31,680. Which should cover most tracks right?

If I push the voltage up to 3.5v per cell, I get 28.4 to 48.6 mph with a motor rpm of 34,650.

Then if I want to do speed runs I can throw in a 4s pack for 34.6 to 59.2 mph at 3.2v per cell with 42,240 motor rpm. Push if to 3.5v per cell and I get 37.8 to 64.8 mph with a motor rpm of 46,200.

If I could only draw what I see in my head, then afford to build it, and finaly get to play with it... Last edited by DrKnow65; 12.19.2007 at 02:34 AM.
