By contrast, flap lift in cruise flight adds only to unwanted twisting moments.... We removed the trailing spar attach strap. Then we offset the two outboard holes on a new strap by 90 thousandths. After flying flight two today, the ailerons sit perfectly flat with no roll component. There was no adjustment to the flaps. They look good on the ramp (especially when you look at them simultaneously!). Now the real ponderance. Should I make both left and right new trailing edge straps with 45 thousandths correction on each side? This of course would minimize that finger nail thickness of body work error..... Regarding flap reflex...... This is a vintage 1987 glacially slow build 320. I remember a long time ago that you almost convinced me that my FB 360 circa 1996 had the fillets set to the 7 deg reflex. "almost" because my manual still said to set them 5/8" high (or so). I thought you were working the FB aspect. Are you saying ALL 320/ 360 vintage fillets are molded correct to 7 deg reflex? So only the 235s were to be reflexed? Could Lancair maybe mention this manual / blue print error in a SB? But alas Mark and I both concur that about 3 degrees vs. 7 is indeed faster. Anyway, yes they are reflexed and surely they are supposed to be back in 1987, no? Convince me. BTW, the VEP up pressure switch lasted 2.2 hours. Not bad from what I hear. Lucky to have a spare new style switch in my parts bin. More data collection tomorrow.
