The Spree flies very nice indeed. It even ROG's from a quite rough grass strip with a quite dull battery pack. The plane has been flown in 4 m/sec wind and it is rock steady. For acrobatics height is tradet for fun width the standard mototr setup. Manouvers successfully performed: inside loops, rolls, barrell rolls, stall turns, hammer heads, inverted flight, cuban eights, spin, flip, rise off grass and landing on grass. Dead stick landings is no problem as the plane will slow down to nearly a halt without stalling (flat bottom airfoil).
