How to determine motor size in wizard, hub motors ?

Great tool thank you !

From the image choices for motor size in the  wizard, I just see images of motor size, weight, and type. Yes simple setup wizard.

 Not really sure which one to choose for size, I don't know the weight, but they're out runner motors, hub motors for skate board.

I've done the detections  for mini = 10 amps, small = 17 amps, medium = 27 amps, these are unloaded tests. Are these the settings I'm supposed to use  for motor max ?

The motor specs listed are 500 watts cont. 1300 watts max, and 50 amps. The specs were tested with 6s and I'm running 10s if that makes a difference.

I'm running them on a Flipsky 4.20 like my buddy who has it set to 30 motor amps for now, can we safely go to 50 amps ?
