Re: Gearbox efficiency??

That's a good explation of how to estimate the efficiency of the gearbox/drivetrain. And the accuracy of your estimate may or may not be very important, depending on what it is you're trying to figure out using the calculator. You could plug in some different numbers such as 85%, 90%, and 95% and see what difference it makes.
