his Lancair (powered by a os61fx). He waxed me. His Lancair air flys more like a jet than a prop.
As I said in the post 31 of this thread, you should expect that.
When I asked him how he glassed his wings, surprisingly he said:
"I assembled the wing according to the instructions, no glass just lots of epoxy!" Wow, I was impressed with how much stress he has put on those wings, yet it is flying great.
Not sure if you’re trying to tell me that I wasted my time reinforcing my wing. Yes again, what I did was over kill. But The Picture I posted revealed, on my wing at least, gaps in the spar construction.
If your trying to convince me I should fly the plane with just extra epoxy at the root (leaving the Spar not intact), well thanks for the recommendation but its winter up here with 6 foot snow banks, I'm not flying, I've got the time and unlike the many comments on the many threads about how we should fly this plane, wing folds, bumpy flights etc. I don't have to worry about that stuff now. I created a lot of strength without adding a lot of weight with a few future modifications in mind.
As I and others (like SDCrash) advised: A generous amount of epoxy at the root joint (mixed with CF, Kevlar or Fibre, Milled Fibre), a good snug wing joiner if the one out of the box is a poor fit, and 2" of Fiber around the joint is a good idea. Inspect your wing closely for defects or poor construction points and fix as you would any ARF.
Does this cover everything? There were still comments of wing fails beyond the Fuse with little details. Could be contruction defect, over stressed flying ... If you think your going to fly this puppy hard and fast, the extras reinforcements would be a good idea. But Hey it your plane.
Hey! Maybe I should try swapping the Saito 100 from the Lancair for the os91fx/Tuned Pipe (13.5X11) off my Tucano and really stress test the snot out of this overkill wing.
