The BLACK STAR 5-250 is a four-stroke radial engine and was developed over a period of 18 months together with experienced German engine specialists. A high processing quality, longevity and a good price/performance ratio were aimed for during the development. The 5-cylinder engine is particularly well suited for models such as the Tomahawk Design Wilga with 3.70m wingspan - but can also be used in larger and heavier models.

Features:
- Approx. 250g lighter than comparable engines in its class
- Same dimensions as comparable motors in its class, therefore 1:1 interchangeable
- More stroke than comparable engines in its class. This improves suction, does not require an additional fuel pump, reliable running.
- Increased torque due to longer stroke
- simple and therefore robust construction of the motor
- Long maintenance intervals
