Motor Gimar UFO EVO 9 Transfers

New Saturn 9 Evo .21 nitro track racing engine built from OS. The power plant uses the new M.E.S. (multiple exhaust system), which has 9 ports with 4 exhaust booster ports and the special shape ensures maximum performance. The crankcase is specially machined from OS to work perfectly with the 4-port reinforcement sleeve and the crankcase has been black hard coated to increase hardness and stability. Also new is the DLC-coated crankshaft with triple tungsten counterweight and silicone insert. The updated design optimizes internal mixture flow while the lightweight shaft improves agility. While the 3-needle carburetor allows for better idle and faster return to low RPM after acceleration. The engine features are completed by a new combustion chamber insert specially developed for use with 16 percent nitro fuel. A 25 percent insert is available separately.
