Right, I did not do math, and I say t is only my bet if everything else is equal, because there could be several reasons which could be diffent between flights, for example mentioned temperature or any other atmospheric difference ... and I did not do it because it is too complex. There are several thing coming to equation:
1/ drag of lines which is higher on longer lines so makes inward moment
2/ fuselage moment (out of circle) which is lower on longer lines so makes inward moment
3/ unequal wing drag on left/right is lower on longer lines so makes inward moment
4/ prop moment of angled prop disc which is lower on longer lines because air comes more perpendicular so makes lower outward = relative inward moment
yes all those things caused by different radius are very small, in range under 1% (and some of them far under), but almostnothing + almostnothing + almostnothing + ... + almostnothing + almostnothing = something
plus if you compensate such moment only by lines (in the case that fuselage moment does not change with yaw angle), it can make visible difference in yaw angle additionaly all multiplied by centrifugal force / G force (relative to ground stand). To that conlusion leads me one experience happened during initial trimming of new model with OS .46 - I lost 5 g weight during flight from tip weight (temporarily fixed by tape) ... motor went immediatelly rich ... when I installed it back, motor worked as before - all without needle adjusting.
2, 3, and 4 are almost nothing. I didn't calculate 3, but shee-it, Igor. That's only three almostnothings, not enough to count, and not as significant as a little bit of wind, which has a trivial effect.
I hadn't calculated #1, except the amount of rudder force needed to balance it. Here is a revision to the spreadsheet that has incremental leadout position needed to compensate for the yaw increment of the extra line drag. It's .032 inch (0,8 mm to you). The least adjustment I can make to my leadouts is four times that amount. I never noticed that affecting engine run. I calculated this for level flight. The amount of leadout increment needed for maneuvers may be another .01 inch. You are welcome to calculate the exact amount.
