Not enough RPM! For some reason, running a Speed 900 in Drumroll II hasn't impressed me as much as the original one. I think a large part of that is due to the drum being significantly lighter than the old one, as nothing else has changed. It uses the same batteries and same gearing as previously but just doesn't seem as impressive. In order to keep up the destruction with less weight, the RPM needs to increase and the best way to do that is to go brushless, so I'll be looking into that soon.

Sorry Tony, I seem to have hi-jacked your thread with my updates :P
