Tall Paul.....I certainly understand your concern using "alternative" flt control rigging....but I'm not flying 10 oz or even 10 lb airplanes.... all are WWII vintage aircraft and the lightest I have is 29 lbs and my biggest is a Ziroli B-25 @ 40 lbs loaded with fuel and bombs.....Being an Aircraft Mechanic and working on large commercial aircraft daily has given me some insights on different ideas to try.......and I qualify that by saying its done using "small" changes to flt control rigging....and then flying my planes to see how they respond....and I read your posts along with several other of your Aerodynamic sharpies with great interest....I have learned alot from you guys.......but with that said....I do experiment time-to -time trying to gain an edge by making changes...and if they appear to work better....why not share that....even if at times it seems contradictory to mainstream aerodynamic thinking......Bill
