Wing with ribs

A friend said he was having trouble visualizing the wing without the ribs, so my work tonight was basically just grabbing the aileron from downstairs, installing the tip attachment (yay), bolting it on, and taping on the ribs.

Here's what I decided at the tip.  The TE was flattened and riveted to one side of the LE.  I added a small stub extension (?) that bridges from the TE to the opposite side of the LE.  This means the aileron is technically flat at the very end, but this seems the cleanest option for the lightest weight and least fuss.  From watching videos of others' Goats, the aileron seems to get fairly stressed in this area on landing and needs all the structure that makes sense.


Here are a few long shots down the span to show the airfoil profile a bit better.

 

And here are a couple shots looking down the control line guides.  They're still just stuck on with tape, but will be epoxied on and lashed with some glass tows to give the bond some structure.
 
 

Thanks for reading!
