AXH
AX Hydroplanes (50 MPH) are for 12-year-olds and up. The AXH class allows young drivers to gain experience to better prepare them for the larger and faster classes. When a young racer hits 16, he or she can move on to one of the adult categories. With no upper age limit, AXH is also great for those returning to racing, those preparing for faster hydro racing, or those who primarily want to have fun. Women tend to be very successful AX Hydro drivers, as their smaller physiques work well with these lightweight hulls.
