I've read numerous posts addressing the low flap and the need to bend a "joggle" to get a smooth transition. What I haven't seen answered is why my QB flap skins come up short;

Why would this be?
Still somewhat concered about the low flaps so I thought it would be good to get it straight from the mothership.

Answer;
It can vary depending on the wing incidence form flush to below a 1/2" like you have. I have
even see one side flush and the opposite will be down.
From my experience with this kit so far I've learned that if something doesn't line up I probably made a mistake. This whole flap to fuse issue doesn't make sense. Too many builders have ended up with the same outcome. Then there are just as many who have had the flaps line up perfect. The only builder variable I see is wing incidence. But to tuck the flaps the wing would end up with negative instead of 1/2 deg positive.
I know, its a farm tractor not a Swiss watch. But like many I want to build the best ship I can.
