Is there any reason why the particular gear ratio between the rotor and the
output shaft (not sure if this is the proper term) was chosen?  Would there
be a way to modify this so that the PSRU was essentially integrated into the
motor?  So, for example, so that 4 turns of the rotor were necessary for one
turn of the shaft instead of 2?

Just a thought, but might save alot of weight and one of the major risk
factors of auto conversions.

I am not sure what you mean by "integrated".
Can you come up with a sketch?
