That’s the fuselage finished ready for painting but if there’s anything you’re interested in that I’ve missed just let me know.
Now the wings. When building scale fabric covered wings we can’t use the normal modelling technique of top and bottom spars with or without sheeted leading edge (unless that’s scale of course!) as the fabric needs to sag in-between the ribs. Unfortunately this “D box” is what gives the wing most of it’s strength but I’ve devised a system which goes a long way to replacing the strength whilst retaining the scale appearance.
The wing has a front laminated spar and a spruce rear spar to which the hinge is attached, if the wings weren’t folding the rear spar could be missed out altogether or at least made from balsa to save weight.
The front spar is a spruce / balsa / spruce laminate with the balsa extended to go through the leading edge with the direction of the grain from LE to spar. The ribs are made in 2 pieces; the top front section is added after the composite spar with additional sections as “riblets”. The leading edge is 2 lengths of square balsa glued top and bottom of the balsa lamination.
Before covering, the ribs and more so the “riblets” are very vulnerable to damage whilst you do the other 101 necessary things to the wing. The answer here is to make a small hole in each of the pieces, it’s easier to do this before gluing in place, and then thread some strong cotton through the holes to make a “necklace”. After gluing in place, soak the cotton (button thread is the best) with thin cyano. It’s amazing how much this cotton also increases the torsional strength of the wing.
