Thanks Stephen, Ken & Richard for your advice. It's unanimous.
@ Stephen: Oh yes, I messed up big. I should have tried one and not all the planes and elevators all at the same time. It would have saved me a lot of material.
@ Ken: There will be more trying out things before ruining large amounts of Evergreen
@ Richard: I totally agree with you. I have little to no experience, and it is something I have to earn. I do not give up easily though.
...And back to square one.
I carefully looked at Ken's Fokker V.23 and Ron Kootje's Caproni Ca.3, two of the wonderful builds on this forum. Ron was kind enough to send me some photo's without the Photo*ucke* mutilations.
So I gave it a try. I had some 1.5 mm balsa lying around. I glued to strips together using ordinary wood glue and shaped the core of an elevator and then two strips of 0.5 mm styrene around it. The styrene strips are a little wider than they show on the Digmayer plans to allow the the bending of the trailing edge.
I must admit, it was much easier than I expected and I am happy with the result. I am going to make the wingtip the way Ron did for his Caproni. This was just a trial but I think it worked out fine.
Today is a holiday in Holland and I'll try to get some work done.
Thanks for looking in.
