This is exactly my feeling too. Although the speedcalculator and these forums are a great help, it seems impossible to chose 1 motor and getting it right from the start, especially if your setup is different than common setups.
If I understand correctly:
- larger can motors with the same kv rating produce more torque than smaller can motors.
- lower kv motors produce more torque than higher kv motors with the same can length?
So if a have a setup geared for 40mph and I need more torque (and don't want to sacrifice speed) I could:
- get a larger can motor with the same kv rating;
- or go for a higher voltage setup with a lower kv rating/ same can length...
