High power—low weight
Innovation is excellence; so, when DLE added innovations like improved crankshaft bearings, and a better piston/cylinder fit to their engines, serious R/C pilots got very excited. The DLE-61 weighs four pounds and cranks out over six horsepower from a durable and long-lasting engine.
Extras like an airplane-specific carburetor, muffler, standoffs and electronic ignition boost performance even further. It's a solid 60cc engine at the best price you'll find.
