Andy, well, since I originally posted my Ventus B story I tried again the other day. It worked but airspeed indicator was blanked out completely by cross control. I didn't remember that happening before. However it was doable with sound alone. I didn't try it without the trailing edge dive brakes open and would guess that without the extra drag it would be harder to maintain slower airspeeds to reduce side loads on the tail and rudder. Any aerodynamicists out there that can do the rough calcs to see if load limits would be exceeded? Or are there even side load calcs available?
