Fantastic DH.91 built and flown by Peter Harbusch. At 1:8 scale and 4 metres wingspan and 2.7 metres length this is a large scale model which looks impressive in the air. Take off weight is ~20 kg. The wing profile is NACA 2415. The four motors are brushless 1000W with 15x8 vario-prop. 5 x 5S-5000 lipos are used for each flight.
