  • Designed to incredibly tight tolerances for improved compression and maximum fuel efficiency.
  • A redesigned, lightened piston skirt delivers supreme throttle response, fuel economy, and durability.
  • A rear-mounted 2-stage Pitts muffler reduces back pressure and increases overall power.
  • An aluminum alloy crankcase minimizes weight while sealed crankshaft bearings maximize durability.
  • A customized, pumped DLE carburetor delivers fuel perfectly during the most aerobatic stunts.


For tight airplane cowls, a rear exhaust setup makes all the difference. The DLE55-RA dishes out 100 more rpm than the DLE-55 with performance perks like a redesigned muffler, lighter piston skirt, and updated electronic ignition unit.

The increased throttle response of the lightened piston is ideal for warbirds, aerobatic aircraft, and sport planes alike. That, with the "extras" that DLE throws in and the superior adaptability of the rear exhaust setup makes the DLE-55RA perfect for moving the really heavy birds.
