Hi, Paul....after disassembling my Ross PRSU, it appears that it is  in

fact, a 2.85 to 1 ratio,

because it does reverse the direction of rotation.  My next question is,

what direction (clockwise

or counter-clockwise) does the flywheel rotate when viewed directly

facing the flywheel?  Thanks

in advance for your reply. Paul Conner, Mobile, AL

Paul  Have another look, maybe count the turns ratio. I think you will find
that if your drive reverses the direction of rotation you have 2,17.
