From the picture, it looks like exactly the same motor and wheel. One of them has the specs wrong then.

However, they come in a variety of RPMs, so you've got to find the right one for the right job. I have found that elevate and rotate systems should run between 4-12 rpm. Use 4 rpm for extreme accuracy and up to 12 rpm for high speed (although personally I think 8 rpm is fast enough for most purposes). A few years ago I found the same motor/gearbox configuration running at 4rpm @ 6v, bought a couple (should have bought more) and they've been working great as elevate and rotate motors in the Navarrone Gun and Tiger ... powerful, reliable, and cheap ... can't beat that combination. The motors referenced above run at 22 rpm @ 12v, so they are about twice as fast as needed if used by themselves. You could use them to drive a 2:1 or 3:1 gear, pulley, friction wheel arrangement, but then that starts complicating the design. Recently, when I built the elevate/traverse for the Brumbar I had a pair of the faster motor/gearboxes in the workshop (I think they were 16 rpm @ 12v), so I solved the problem by installing an inexpensive speed controller that could be manually set using a trim pot (see http://kitsrus.com/pdf/k67v3.pdf for a description of the kit, available from various distributors for approx $20). By adjusting the pot I could dial in exactly the right speed to balance accuracy, smoothness of operation and end-to-end speed. It seemed to work well for Desert One in the last battle, but only time will tell if it's a rock solid solution. It did work well enough that I am going to install one of the speed controllers in the Navarrone Gun so that I can run everything off of the same 12v battery.
