Hasi Tuned rear engine backplate & pressure chamber

Coming from Hasi Tuned is a new rear engine backplate for O.S. based .21 engines as well as a pressure chamber set. Starting with the backplate, the part offers reduced friction while improving mixture flow inside the engine thanks to a unique shape, resulting in improved torque in the bottom to mid RPM range. The backplate comes in a natural silver colour with engraved Hasi Tuned logo. Also new is a pressure chamber set machined from aluminium and sporting a black surface coating and a laser-etched logo. The pressure chamber will be fitted into the pressure line between the exhaust and the fuel tank cap, improving overall performance and idling of nitro engines.
