100m, that's quite a distance

My axe tests have mostly been with the axe unit clamped to my workbench, but I noticed a similar thing when I ran one test without it clamped. Common occurrence with axe weapons. Not sure how well it would work, but maybe having magnets in the base of the machine will help keep it on the deck and reduce the amount of wasted energy, although that would only work for Robo challenge events.

Sounds like a nice improvement in any case though; you able to upload a video of the 22.2V tests?
