This was at our hotel during the Bad Apples fly-in. It’s clever, well-implemented and seemed worthy of sharing. Of course it requires welding and steel cutting but capable humans without those abilities may be able to come up with clever substitutes.
One caution is that all the paramotor support is on its frame bottom. That’s asking a lot given how the main mass is 2 feet above, making fore/aft rocking forces quite high. Some machines may not handle that well, causing cracks, or worse, breaking completely and falling off the back. It would be wise to support the frame from ABOVE the engine–maybe with an extra strap–to take some of that fore/aft movement. Add a simple bike lock through the frame and stand could to provide some minimal theft protection while preventing the motor from tumbling off the back, possibly causing damage to following vehicles.
Good luck.
