Amperage Calculator?

Ok so it should be total gear ratio not just trans ratio. I thought that might be what the problem might of been. BTW this setup has been done with 25 pinion and 36 tooth spur with a lower gear 3905 tranny instead of a higher gear 3906 tranny and heavier revo and the best results were 91.2 mph on gps and radar.

Dont include the pinion/spur. Just put in the diff ratio multiplied by the transmission ratio and put it in the transmission ratio entry.
