West Wings Skylark build thread
Happy Days:
Watch this video carefully. Although this modeller has modified his two piece skylark wing to take an extra brace near the LE when I stop frame the image showing the 1st rib it looks to me as the joiner (Dihedral Brace) fits between the upper and lower parts of the main spar.
Your picture of the plan shows the brace to be 172mm long. Half that length equals 86mm and 86mm from the root of the wing will take the brace up to the edge of the third rib.
What I'm saying is that, a) the brace is not supposed to go any further into the wing, and b) the third rib is in the correct place.
If you want to, before you do anything that you might later regret, bring the wing, plans and instruction down to my place and I'll have a look at it.
I've looked on many web sites and I can find no one else who has had a problem with this aspect. With all due respect to you, that fact suggests to me that you've missed something either in the instructions or the plan, David.

I might just take you up on that Keith... It'llprobably be in the new year at this stage.
Looking at that video, it really does look like I did it wrong... :? I have to say, the instructions are so incredibly clear I just don't know how I could have got it wrong... :shock:

The beauty of balsa construction, anything is fixable.

Happy Days:
I totally agree with you John, mouldies are fine to look at, and fly well but are a real pain to repair. Personally I try to avoid them :lol:

So, after meeting with Little Keith, I have started modifying/repairing the wing before the plane even gets flown! :-\
This is what I started with...
As you can see, the dihedral brace sits proud of the wing rib. That's what made me assume that the brace needed a cut-out on the underside of the wing.
Unfortunately, doing that (making a cut-out) resulted in THIS... >:(
Getting busy with a junior hacksaw blade and a scrap of coarse sandpaper allowed me to deepen the notch in the ribs.
And a little bit of sawing and sanding gave me two light ply "mounts" to fit against Rib 3, two strips of light ply and balsa to recover the base of the wing and support the brace and two pieces to fit to Rib 3 to hold the brace (as it's too short to make it to Rib 3).
I think that was the easy bit... Actually gluing in the piece to hold the brace is going to be fiddly. L. Keith has also kindly donated a scrap of light ply from which I can fashion a replacement brace (for the inevitable hard landing).
After this, I still need to see about removing the covering from the tail plane to correctly create the bevel to allow deflection.
Maybe, just maybe, she'll be ready to fly for the spring! It's only taken approx 49 weeks so far! :o
