    Does your Alpha Alpha 5 Bravo look like mine?  Gl

    I’m not sure what this has to do with Historical Charts and Mapping Gary, or even celestial, but since you ask, I used to fly one a bit like that, except it was an ‘AA5 Traveller’ G-BEZF.  In fact, I passed my pilot-nav test in her, so I suppose it does qualify a bit, just.  I got in a knot with the fully-castoring nose wheel first time out, but apart from that it was a really nice aeroplane to fly.  Three things amazed me: the speed for such a boxy fuselage; the fact that the wings were supposed to be glued together, not riveted; and that interesting tab on the elevator.  It worked in the same direction as the elevator movement, not the opposite (see your photo).  It was an “anti-balanced tab”.  Presumably with a short fuselage and a large cg range, you needed a large elevator to flair under certain conditions, but you didn’t want to risk overstressing the aircraft if you sneezed at high speed, so they fitted the anti-balanced tab to increase the stick force per g.  DaveP
