Hi, thanks for the input that's exactly the info I needed. Good to know about the 250mph limit, I hadn't considered that at all. How did you get the speed down on let the good times roll? 200 mph is quite a bit to loose!

Most / all drum spinners that use belts have the drive motors behind the weapon motor so it should be ok as is, but I'm going to spend some time trying to rejig it so the drive motors sit between the beater and the weapon motor.
