Good luck on the wings! On mine, the progress was good until I got to the leading edges - if I were doing it again, I'd simply bend them a little more myself to help get a better fit.

Dave, some time ago you recommended an additional bend of the leading edges.
I'm assembling the wings at the moment and remembered your recommendation. Do you think it would be a good idea, to use the vacuum forming method e.g. as described in "Vacuum Forming Leading Edges" http://www.kitplanes.com/issues/33_4...s_21504-1.html
Is your recommendation also for the tank skins?

No, adding the bend isn't hard but it needs to be somewhat precise. There's a flat spot behind the leading edge bend and the top-of-the-rib bend and that's where I had trouble. I should have just left it like most other builders do.
Locate the center of that flat spot clamp a 1 1/2" pipe to the skin. Gently form the skin around that by hand, using some sort of a beam to spread out the load - doesn't take much. If you get it offset that skin is scrap, this bend doesn't come out. At least I couldn't get it out.
If I were doing it again, I'd just leave it alone, honestly.
(If you want to continue this conversation, let's move it to another thread or my build thread or PM me or something, so as not to clog up this Status of RV-3 forum. Thanks!)
