Founded by Roger Newton in 1974, R/C Unlimiteds is the original, and most highly regarded organization dedicated to  scale radio controlled unlimited hydroplane racing in the world. R/CU races both ‘fast electric‘ (FE, 1/8th scale), ‘nitro’ (piston powered nitro-methane fuel, 1/8th scale), and 'gas scale' (piston powered gas-fuel, 1/6th scale) class boats, each finished in exacting detail to represent the full sized original. The boats are capable of speeds of nearly 60 mph and the racing is serious, and not merely a demonstration. We race on ponds all over Washington State throughout each summer, from April through September, culminating in the Gold Cup, raced on Lake Chelan.

It is not uncommon to see both roundnose boats competing against more modern hulls in R/CU!
