O’Donnell Super Sport .21 Engine
Designed in the USA by master engine tuner Steve O’Donnell, the Super Sport .21 is the pinnacle of 1/8 scale nitro racing. It’s a shining example of the “clean sheet” concept – a fresh look at engine construction and components, with nothing borrowed from existing technology. Only state-of-the-art machining and materials have gone into producing this engine with features including the original O’Donnell-designed “big head” machined aluminum heat sink head, dropped down low for a better CG. Available in February.
