Like many people here I'm trying to get a good starting point for setting up my car. I've got the car working pretty good but can use some suggestions on rollout for a 19T and Stock on HIGH TRACTION CARPET. I'm just looking for a general range (in millimeters) that you set your rollout to. Since this information could be handy for more than just myself please try to respond as follows:
Car your using (tc3/xxxs/pro4/etc)?
Stock Motor name?
Stock Motor Rollout Min/Max?
19t Motor Name?
19t Motor Rollout Min/Max?
Anything special you do to keep from cooking your motor when using Max (aggressive) rollout.
Stock Motor: Trinity Monster Horsepower 68w
Stock Rollout: 27mm/30.4mm
19t Motor: Reedy Quad 19t
19t Rollout: 27mm/29.7mm
I am using a small fan blowing on the motor endbell when using Max (aggresive) rollout.
Remember that 1 inch is 25.4 millimeters so please respond in millimeters. Also the calculation for rollout is:
[(Tire Diameter X 3.14 )/(Teeth in Spur Gear/Teeth on Pinion Gear)] / Gearbox Ratio
Gearbox Ratio for:
TC3 = 2.5
XXXS = 1.83
Pro3 = 2.25
Pro4 = 2.4375
