Overview

Tired of wiping down planes after every flight? Yearn for the low cost of gasoline operation? The groundbreaking Zenoah G20ei isn’t just the first Zenoah™ engine with electronic ignition—it’s also the first gas engine from any manufacturer purpose-built for smaller planes that, until now, had no choice other than glow power. Its dimensions are especially well-suited for round cowl models like classic Hangar 9® .60-size warbirds. The electronic ignition G20ei also gives you the cleaner, low-cost operation of gas, plus rock-solid Zenoah reliability in a package that’s small enough and light enough to power any .90- to 1.20-size sport airplanes. Much of this incredible versatility can be attributed to its lightweight magnesium-aluminum alloy crankcase that gives it an impressive thrust-to-weight ratio that rivals many glow engines. Never before has gas power been within the reach of so many glow users.
