Weighing in at only 147lbs (67kgs) and with 115hp (NA) and up to 130hp (FI), the FALCON FL150 is the same packaging as it’s bigger brother the FALCON FL200, but with modified internals. With a service ceiling of 30,000′ the FL150 is ideal for LSA, Kitplane builds, Drone, EAB and countless of other applications.

Just like the rest of the E-Series Higgs line, the FL150 is designed as a clean sheet multi fuel solution. These engines will demonstrate our unique design for achieving the needed horsepower while keeping the weight of the jet burning engine at or below similar AVgas versions of these engines.

Fuel Type and Consumption

This platform of engines has been designed from the ground up to be a true multifuel unit.

Designed to run on industry standard Jet fuel (Diesel (EN 590), Jet A, Jet A-1, JP-5, DEF STAN 91-86, JP-8, DEF STAN 91-91, JP-8+100, Chinese Jet Fuel No 3)

Will also run and perform on all gasolines where necessary, 80,87,91,95 including 100LL along with all bio derivitives.

Hydrogen gas.

BSFC, 0.380 lb/hp-h (231g/kW-h) Pratt & Whitney PT-6 Turboprop by comparison is 0.507 lb/hp-h (308 g/kW-h) (on approach and idle 0.825 lb/hp-h (502 g/kW-h))


Compared to comparable Rotax engines.
