The B-0s were powered by DB 600C engines fitted with variable pitch airscrews. These drove wooden, two-bladed airscrews. Rotax 912 ULS, both with three blade airscrews, are options. Propeller aircraft use one or more propellers (airscrews) to create thrust in a forward direction. Metal, instead of wooden, airscrews were fitted to the aircraft during the flight.
