that's 63 ft lbs at peak efficiency, right?

Also, 25 RPM is 150 degrees per second - a QUITE high arm speed.
I feel like this needs to be reduced further, perhaps with a chain. If it is that fast it will be hard to control. Anyway nice to know some other people know the Cim-u-lator exists, we were thinking of using one also because weve reached our CIM limit because of mecanum drive. But unless your arm weighs more then 40 pounds, one rs550 with a 64:1 transmission will do just fine. I've posted some videos of our team testing an rs550 the thread is here:
