ORIGINAL: otrcman
BobH made the observation that most of the full size WWI airplanes were poor flyers. That's true. I help out occasionally with a large collection of WWI replicas. The two guys who fly them (I don't) tell me that they are mostly poor in the stability and control department. The DVII is perhaps the best of the bunch, but even it has slow ailerons. Most of the problems seem to be lateral/directional. Adverse yaw and slow roll response are pretty much universal among that genre. But that's mostly due to the tiny vertical stabilizers or the fact that some verticals are all-moving with no fixed fin.
I, for one, don't want a model that flies BETTER than the original. I don't want a RE-ENGINEERED version. I'll never fly a full-scale replica...the closest I'll ever get is a scale-flying miniature. And if the original had adverse yaw, then I want to experience what it was like to fly with adverse yaw (and "a boot full of rudder").
