Hi All,
Nicely seen and illustrated Bo, as you say, once seen hard to 'unsee'.
Of course, every kit has it's flaws, no-one, including myself expects perfection. But what is expected is a decent representation of the aircrafts salient points. The wingtip 'thing' is very noticeable once seen, all it requires really is a little time looking at photos and taking in detail. As said, the taper started from two ribs out from the aileron root on upper and lower surfaces, less on the lower surface, all this of course creating tip Washout.
The aerofoil section obviously changed with all this and it is possible to construct approximate co-ordinates using various methods, the section from centreline to a point two ribs out from aileron root was, of course constant.
Copied my notes (photographed them) this morning with the intention of posting same, but still struggling with file size, have to get somebody to show me how to shrink the files. These notes are from back when the original DIII Datafile was published - was it 1988?.
It's all a question of what the individual wants in the final model, if you're happy then that's fine. I say again, the WNW kit is probably the 'best of the bunch', but the wingtips, and this is applicable to all manufacturers, should have been more closely looked at.
Keep on looking Bo, the more you look the more understandable it all becomes.
If Rudi Geringer looked at kit wingtips I think he'd be a bit concerned about possible loss of control approaching stall ! !.
Seriously though, it is a glaring omission and should have been seen, no drawings show it either, apart that is from the l' Aerophile side and front elevation.
I'll try to post the stuff I mentioned, phew!, going for a Cornish Pasty now, nice ones at shop round corner!.
Cheers all, Al.
