More options going with the lower motor. Plus more Torque.

Can you explain what you mean by this? From the specs I have, it looks like the RS 550 outputs 21 fewer Watts at peak power (266W vs. 245W). To me, this is strictly inferior (although not by much). Is there some other factor you are taking into account? I have also heard that because the motor is designed for 18V, it runs more reliably at 12.

We are considering using one RS 775 for each of the strafing wheels in our holonomic drivetrain. Will the load from a drivetrain be too much for these motors and the gearboxes on them? There seems to be some concern about max output torque. Would the RS 550 be a comparable alternative, in light of the greater availability of those gearboxes?
