If you are going to put skis on your machine don't use bungees , they can cause a lot of problems if they break, the attachment breaks or an axel breaks, I was testing a new set of skis by running it around on the snow without the rotor and hit a patch of hidden slush which grabbed the ski, the machine pivoted around the stuck ski and broke the axel, the machine continued to slide stretching the bungee until the now unloaded ski broke loose and the stretched bungees pulled the ski into the spinning prop, the bungees wound up and the ski was spinning , the out of balance broke the engine loose, when the engine fell it pulled the throttle wide open and the prop and engine chewed up everything on the gyro that it could get at, I learned that if a ski or anything else breaks off it needs to stay gone instead of returning like something out of a slingshot.
