Just got back from the FF where today was the maiden flight of the Dr1. All I can say is "AWESOME"!!! The OS.91 is well matched to this airframe and pulls the bird around the sky yard nicely at just below 1/2 throttle. No added weight either with the weight of this engine. You guys who havn't flown yours yet are in for a treat. Ground handling isn't that bad either, even with that confounded skid!

Happy Flying!
