AirRider Easy Build Hovercraft Kitset 

 

Quiet Operation: Unlike the majority of other small hovercraft, the AirRider Hovercraft is quiet in operation. The two contributing factors to low noise are the low revving 4-stroke engine fitted with a specially designed super quiet exhaust muffler and the slow rotating variable pitch propeller.
