Hello Group
Look what I found out, after I start to build up my wings:
- There is a gap between the rib and the spar-top-flange, 2.0mm ( 0.08") at the rib to spar, 2.6mm ( 0.1")at the rib to skin. This is the worst case in 2/3 centered over the wing, so 10 to 12 ribs are effected.
- At each end it is better, the gap there is within 0.5mm ( 0.02") to 1mm ( 0.04").
- The angle at the top-web-flange is 90?, on the plan it looks that it should bee less then 90?, I would say 87? or so.
- The distance from the top to the bottom flange is 195.0 ( 7.67") at both ends and 197.0 (7.75") in the middel (2/3) area.
- All the rib- flanges are 90?, the ribs are straight.
- The bottom side is ok
On the second wing, it looks not so bad, but also not good, the gap there is between 0.5mm ( 0.02") to 1mm ( 0.04").
To all that, I attached 4 pictures which shows the problem exactly.
I askd Vans, they did not had something like this. They tell me to bend the flange down, but I think, the anodizing will crack. And or center the gap ro both sides of the spar.
What do you think about this? Could you support me with a few mesurements at your spar's?
Thanks alot
Dominik
