...It would double up as a sideslip indicator. Seriously though, this 'aeroplane' seems to have the aerodynamic characteristics of a drunken chicken. I finally managed to get one airborne, and at an altitude where getting out and walking was no longer the most sensible option, only to have it go into a spin every time I tried to turn at more than 1 degree per minute. I can see why you shouldn't try tight turns (the inner wingtip will probably be going backwards), but even keeping it straight seems to be an exercise in futility. Looking at the replay confirmed the problem - it is very prone to sideslipping, and any aileron input makes the whole thing instantly divergent. I suppose the pilots of the real thing could detect sideslip by the deflection of their moustaches or something, but how do other sim pilots manage to keep it pointing in the general direction it is heading and vice versa?
