Describe
MWfly aviation engine is a high-performance engine specially designed for aviation in Italy, with Overhead camshaft engine and chain driven four cylinder four stroke horizontally opposed fuel engine. It can use motor gasoline or Avgas, has low fuel consumption and economic characteristics, and can be widely used in various helicopters, fixed wing aircraft and UAVs.
There are many reasons to choose it:
Strong adaptability
16 standard engine versions available, with power ranging from 100 horsepower to 155 horsepower, direct drive or gear transmission, propeller rotating left or right, traction or propulsion, weighing less than 85 kilograms (187 pounds)
Special design
The engine modification was specifically designed from scratch, with all technical details adopting the most suitable technical solution for the needs of sports aircraft. All engine accessories (expansion tank, engine control components, hub, voltage regulator, start relay, etc.) are pre installed on the engine, reducing installation time and cost, making it possible to replace the engine on the aircraft within 1 hour.
Price advantage
Affordable - MWfly aircraft engines have the best cost-effectiveness: fuel consumption is equivalent to a 2.5L car, and 80 liters of gasoline can be used for about 6 hours. Equally important, MWfly aircraft engines are easy to install and maintain, and the engine can be inspected on-site using internal control surface inspection ports.
It is mainly divided into two major series and more than ten models to choose from.
