Re: Ed's response to the S-1 Prototype Virtual Tour.
I'm integrating the mod now into the new wings from the start of the build.
My first question is based on the A-Wing Mod for a Sonerai I. I have plans for the angle modification on the 9 rib Sonerai II and the Sonerai II LTS, But I do not have any drawings for the Sonerai I A-Mod. Both sets of S-2 plans show the two-piece reinforcement angles ending 43†down the wing from the spar flange root. Is there a similar dimension for the length of the Sonerai I angle?
I have modified the wings to include 3 more ribs per panel. The inner 48 inches use the rib spacing of the Sonerai II LTS providing structure for a wing walk and more anti-drag/compression reinforcement. The outer 40-1/8†use the rib spacing of the Sonerai 1. The lightening hole spacing is also similar for the respective inner/outer II LTS and S-I hole specifications. Spar cap lengths have been originally cut and drilled per the Sonerai I plans, but I am considering replacing these original upper caps with longer lengths rather than using filler strips to provide a foundation for the angle piece. I would also rather use a one-piece angle of the required length, rather than splicing two pieces. I plan on trimming the bottom of the angle 1/8†and lower it to be even with the lower side of the upper caps so I can better dimple the upper spar flange and rivet on the skin. AN3 bolts will also be used on the angles and verticals so I can remove the reinforcing angles cap angles if required to dimple the upper spar flange before riveting up the wing. Any thoughts? Once I get some guidance on the length of the reinforcing angle I'll be making progress again. I'm a month into retirement and it is good to be working on the plane again.
One more thing - what is the best way to Alumaprep and Alodine these big parts before riveting?
Thanks
John
