My last paramotor was the Air Conception 130 electric start with clutch. The main point for me was safety. However, I did blow a launch, cut the engine, but the leading edge went into the prop. As it w still spinning it did quite a lot of damage. I now have a nitro 200 electric start and love it. Hit the cutout and the prop stops instantly. I wouldn't go back to a clutched machine, more weight and more to go wrong. However I am very mindful of my startup procedure as a prop strike would be catastrophic!
