This causes more drag. This can be corrected by placing a washer under the bolt attachment of the stab to reduce the angle of incidence to reduce the down deflection in cruise. Ideally the ASW 24 should have a tail tank. Anyone know of someone that made this mod on the 24? Regards Udo What you really need is a lead weight on a track mounted in the fuselage driven by a small motor. Move the weight back for climb. Move it forward for cruise :-)) Actually, the flight research department at my University had this installed in Navions. I guess I'm only half-joking... P3 Reminds me of the 'mercury pump' gadget Moffat supposedly revealed to his fellow contestants on the start grid one long-ago day. Didn't matter whether it worked or not, the other guys were so psyced out they were beaten before they hooked up. Bob Johnson Moffat comes from a racing sailboat tradition, where trickery is admired if not the norm and where clever rule beating devices are constantly developed. I heard of one sailor who, not allowed ballast at his weighing, put several boxes of tomato soup (highest specific gravity) in the bilges as crew provisions. I never met George and I'm not accusing him of cheating, but the out-psych'em strategy is certainly a NE tradition. |
