CHC:
So, are you saying the motor selector is not picking the correct motors for the application?

Nick:
The only calculator that factors in weight is the motor selector. I know it seems like there must be a lot of duplication of code on the max speed calc, motor selector, and solver page, but believe me, each one works quite differently because of the focus for each one.

For instance, on the solver, you wouldn't want to figure out how much ballooning you need to achieve a certain speed because you really don't want it. Likewise, you wouldn't want to calculate the motor kv needed based on vehicle weight. Weight affects motor size, not the motor kv value.

The motor selector was intended to help newbies with a starting point for which motor to pick based on other more easily selected parameters.

The motor selector and solver are intended more for initial planning. Use the solver to try a bunch of different scenarios. Then use the motor selector to get a range of motors to use. Finally, use the top speed calc to get an accurate speed rating which takes as many factors as possible.
