Paramotor Prop Stopper (Rope Trick)

For clutch equipped machines | Rope Trick another version

The prop related accident rate of clutched machines appears to be no better than that of non-clutched. Although the prop may not spin at idle, at high throttle settings it will spin up just as fast as other machines as evidenced by the accident record. Further, the fact that a unit is clutch equipped may lure pilots into a more casual approach to their machine while its running. That trust is misplaced.

Francesco DeSantis came up with this safety improvement for clutched machines, the Prop-Stopper rope—an easy-to-build device that prevents the prop from spinning while you start the machine. Even at full power it would stop the prop. Yes, that would obviously be hard on the clutch, but a clutch is cheaper to replace than a hand. And much less messy.

This piece of rope with a short tube attaches to the prop in such a way that it can't spin, even if the throttle were at full. Then the pilot gets buckled in and removes the rope while seated, nearly eliminating the possibility of an accidental prop strike during startup.

The safest way to start a machine is with it on your back like Miniplane maker, Diego is doing here. But reality means that sometimes we have to putz with our machines to get them going. When a motor is being difficult to start, that is a likely time for it to surprise you with above-idle power.
