Posted: Thu May 25, 2006 5:00 am Post subject: Heavy Wing Experiment

I tried eliminating my heavy left wing by increasing the angle of incidence

of the left wingtip.  The theory was advanced by Scott Risan that a change

out at the tip has lots of leverage to affect roll trim.  This contradicted

a theory advanced by Gus Funnel that wingtips contribute nothing to lift so

changes will not affect roll trim.  Anyway, I went ahead and split the

trailing edge of the wingtip and drilled out the rivets holding the aft

wingtip rib in place.  Then I flexed the now limp trailing edge 1/2" further

down.  Happily thinking this would solve my problem, maybe even be way too

much, I removed the aileron trim tab I had been using to avoid large roll

corrections opposite to my original problem, secured everything with duct

tape and a couple of rivets & went flying.  Bottom line: No change.  Gus

wins.
