Hi Don and Roger and Phil. From my drawings ( see the topics " Wing dimensions and coordinates " ) i otain coordinates for wing rib 1 and tip, perhaps it can help you :
These are SELIG files ( .dat ) but you can open with Notepad. You can also view profiles with a free software ( Compufoil for exemple ).( to see with Compufoil, you must change the files extension to .dat )
I saw that DON obtain the dihedral... 1.43°. With the same data ( the plan n°9, the main spar fitting ), i get 1.3° !!! ( inv tan 0.25"/11" = 1.3° )( 11" is distance between upper and lower fittings )
