Dle Engines DLE-61 60cc Electronically Ignited Rear Exhaust Gasoline RC Aircraft Engine with Muffler for Gas Model Planes

Innovation is excellence; so, when DLE added innovations like magnesium alloy crankcases, 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.

Electronic ignition delivers smooth idle, easy starting and
powerful throttle transition, spiral wire wrap eliminates
interference
Muffler designed for optimized power delivery
Enlarged crankshaft ball bearings
Two petal reed valve induction system
Airplane specific carburetor with manual choke
Lightweight piston for fast acceleration, excellent compression and
