I have recently become interested in tackling a minimalist Thorp T-18 project and have been doing some homework. A basic T-18 with just the main tank can be set up for gravity feed and the AeroConversions AeroInjector seems to work just fine with gravity feed. Does anyone have any experience using this or a similar throttle-body injector on a small aircraft engine like an O-235? Pros, cons, recommendations? Cheers, Matthew
