Advanced CNC machining, tight tolerances and refined porting improve compression and fuel burning efficiency to raise performance and reduce exhaust residue.
Redesigned, lightened piston skirt provides better throttle response, fuel economy and resistance to wear.
Included 2-stage Pitts muffler reduces back pressure and increases power.
Also features a special aluminum alloy crankcase, high-quality sealed crankshaft bearings and DLE-customized carburetor.

More power!

Producing 100 rpm more than the DLE-55, the DLE-55RA screams performance - from the lightweight piston skirt that speeds throttle response to the rear exhaust design that permits easy tuned pipe installation. Ideal for warbirds and aerobatic aircraft, it comes with engine standoffs, electronic ignition, spark plug and Pitts style muffler.

IMPORTANT NOTICE: MacGregor Industries Ltd highly recommend using NGK-CM6 spark plugs with this engine for optimum performance.
