Slop was a poor choice of words, maybe flex describes it better? Here's my thinking, let's say (just throwing out an even number not to be reflected in actual weight) plane weighs 1000# on takeoff, each wing is tasked with 500# lift (yes I'm aware the canopy ads some), lift is created on the downward surface of the wing, let's say a residual amount is transferred to the upper surface of the flaperons 5#? Now factor in 10 microns of a gap in every hinge, ball-n-socket joint, poly bushing compression, and torsional flex of tubing. Ounces make pounds just like microns make millimeters so estimating both to be 3mm in the raised position at the outward trailing edge. Will that be an insignificant change of .05 mph or 5mph difference in stall speed? It seems small but over the whole surface of them it may add up. All my numbers should be considered X and "residual" as being greater than 0.00X% I hope this is perceived as an honest question, I'm certainly not nit-picking, I'm kinda continuing the discussion last week regarding the seemingly minor changes made over time that really bumped up the cruise speeds. When I go to remount the wings this year I'm considering throwing pulleys on the roof, 5# weight and rigging it to pull up on them and balancing them straightedge even with the underside. I appreciate the feedback, thanks, Max
