Infraction SPEED CALCULATOR??

[Jluther@becoinc]

When using the RC SPEED CALCULATOR what do you guys use as transmission ratio.
When I enter 2.8 for the dif gears I don’t think it’s right. Maybe it is.

Trans ratio is 1. Diffs ratio is separate, as are spur/pinion.
Which calculator are you using?
2.8 is the correct ratio for GP5’s, but it sounds like you might be entering it in the wrong field.

When I put 1 in with 22 pinion, 46 spur,1650kv ,100mm tires, 8s it said I should be going 258 mph
