Thanks Dave,

I will contact the people from your first link to find out the speed, torque and current specs on that motor. Maybe it'll work maybe not. The one on ebay is still too slow for what I need. Thanks for taking the time to do some research though.

The RS550 motor has nearly identical specs as the FP9015 Motor. Pull the pinion off and it will fit anywhere you put an RS550. The mounting holes are the same. You can get these FP motors from AndyMark for $13.

Jim,

I have thought of the FP motors all along but they will make my mechanism much slower. While the stall torque is close between RS-550 and FP, the free rpm is 15600 for the FP and 19300 for the RS-550. After they go on the 256:1 planetary the output difference is rather large. However this is still my back up plan but I hope I can find the RS-550s.


My hope is that some teams out there never used their 2008 RS-550s and are will to sell/trade/give to me. So if your reading this and you think you have some please contact me.

Thanks a lot to everyone in advance.
