    Product description

    For tight airplane cowls, a rear exhaust setup makes all the difference. The DLE20RA offers the performance of the DLE-20, but with performance perks like a redesigned muffler, lighter piston, and updated electronic ignition unit.

    Even before your first run, the DLE20RA is ideal – it installs easily thanks to beam mounting and its rear exhaust setup. Electronic ignition gives you a sure-fire start every time and, once you’re in the air, the pumper carb delivers consistent, reliable fuel flow through the craziest acrobatics.

    Add in the “extras” that DLE gives you – gasket, bolts, throttle arm extension, exhaust extensions, muffler, spark plug, manual, and more – and it’s no surprise DLE is one of the highest rated model airplane engine manufacturers in the world.
