AX Hydro

AX Hydro

Junior Class Hydroplanes are made to skim across the water, with only the propeller and sponsons (the projecting parts on either side of the hull) touching the surface. The trick is to allow just enough air to rush underneath the boat, giving it the lift that allows J Hydros to hit speeds of 45 MPH or more. Drivers steer with the right hand and squeeze the throttle with the left, kneeling in the cockpit and staying low to minimize drag.
