This is the 1:10 scale remote-controlled hydroplane boat modeled after the Ferrari Arno XI that raced to a world 800kg-class speed record of 150.49 mph in 1953. Replicating the same distinctive plank-on-frame top-deck construction of the full-throated speed boats that became popular worldwide in the 1930s and 1940s, the boat also features the back-swept exhaust manifold and a period-authentic engine cowling. Its watercooled, brushless electric motor drives the polished beryllium/copper alloy propeller for speeds up to 22 mph—making it even faster than 1:10 scale speed. The boat can be controlled up to 500' away from its radio transmitter; a skag mounted to the right sponson provides precise turning assistance during racing. The on-board battery provides 20 minutes of operation from an 80-minute charge using the included AC adapter. Remote includes four AAA batteries. Ages 14 and up. 22 3/4" L x 7 1/2" W x 8" H. (16 lbs.)
