Speed Calculator

Ah, well in that case you could factor in weight - momentum is equal to the product of velocity and mass :005:

Unfortunately, the problem seems to be that our trucks go faster than the calculator would suggest (which I still think is related to the actual kv rating of the motor vs the published values). Any adjustments would only cause the top speed result to be slower.

I'd have to believe that either the battery voltage is staying higher than the input value or the motor constant is a bit higher than spec'd. That's the only thing that can account for higher speed than calculated. The thing is, going faster than the theoretical calculated value just isn't possible unless the user is incorrect in one of their input variables. I'd really like to know all the details of someone going faster than the calculated speed, especially if it's GPS verified.

Well, AFAIK, Squee the one that seems the most inaccurate so far. This was what he was using.

EDIT: Squee posted his response before I got mine in...

Version 1.3, not much new, just added a few warnings; one of which is for the 40krpm motor limit.
