I have built 5 profiles now using Aluminum instead of wire gear
When I lay out the LG hard points I figure 0 Angle of attack ---but when I set them with the bolts ---I force in a slight (within the slop of the bolt) a very little positive incidence....makes me think (probably wrongly) that the 1 inch wide strut is flying a bit to off set the drag....
But then, I also ...again probably anally..... round the leading edge to; I hope, reduce drag
