" -Then, he'd tell me to go solve a r eal problem. -I always had lots of ideas that I thought would be interest ing to try. -He called it mental masturbation. -He'd say, "At least you feel like you're accomplishing something whether or not you actually do." =0A=0AOK, so, now I know the objective. -Any ideas on where to start?=0A =0A--------------- -Ned writes . . . ----------------------------=0AGary said "There isn't anything you can do now except to optimize what you have" =0A-=0AGary, surely you jest???=0A-=0Aof all people I would 've thought you'd be the last to say something like that....considering all the stuff you yourself does and have developedand are developing that ain't "already built"=0A-=0ANed....he he he=0A------------------------------------------ ---------------------=0AGood point, Ned. -=0A=0AWhen I wrote that, I thin king in terms of "there isn't anything you can do now with respect to deter mining fuselage minimum drag independent of wing drag, the wings lift/drag independent of the fuselage or changing the wing-or horizontal-incidenc e -(angle of attack) or related systems, wing length, wing shape, etc." =0A=0AWhat I had in mind was optimizing things like wheel pants, wing tips, antennas, engine, prop, ways to get the weight down . . . -you get the i dea.=0A-=========0A=0ABob,-=0A=0AA while back I read an article about a guy with a Luscombe who put a micro-switch, attached to th e block, so that it touched the back side of his prop. -When the engine w as producing thrust, the crank pulled forward in its journals. -At zero t hrust, the prop would back off. -He was able determine the lift/drag of h is Luscombe and developed his own curves for parasitic drag and induced dra g. -=0A=0AAdmittedly, he treated the Luscombe as a system. -But, it mig ht be a start. -His goal was to find minimum drag to optimize his range. -=0A=0ASorry again Bob, there was nothing after #8. -I can't give away all of my secrets.=0A=0A============0ARadical Race pl ane ideas: -(these ideas are independent of one another. -A classic exa mple of mental masturbation)=0A=0A1. -Move the pilot, instruments, contro ls and everything, back to the back seat; about 2 feet.=0A2. -Use a canop y from an AA1, cut the aft fuselage down to fit the canopy. -Install AA1 seats.=0A3. -Install a battery in the back, aft of the baggage compartmen t, on a slide to move the CG back as far as possible during flight. -Retu rn it for landing.=0A4. -Max range:-=0A- - - a.
