First post on the RV10 site but I’ve been working on the -10 since Sept of 2007.  I’ll go back and update the empennage section later…..

 Spent the day working on the wing tips.  It’s amazing how you can do both wing tips the same and get different results :) 

First step is to trim the wing tips to fit.  It’s about 1/2 inch clearance all around.  I use a cut off disk and then a belt sander to cut the fiber glass pieces.  Anyway, next step for me was to align the flap to full retract, align the ailerons to the flap and then align the wing tip to the aileron.  No problem except the wing tip is big and dust makes it slick so it’s hard to hold.  Use duct tape to hold in place while drilling the tips to the wings.

 Next step for me was to install the wing tip rib to the wing tip.  After all this the left tip didn’t align as well as I’d like for it too.  On my 7A, the left aileron is a little below the wing tip and in level flight and it is quite annoying to the builder so I was determined to insure these lined up “exactly” on the 10.  I took all the cleco’s out (except in the wing tip rib) of the wing tip and re-aligned everything.  The bottom was off about 1/16th of a hole off.  As I’d drilled these with #40 and the final will be a #28 drill, I re-drilled the wing/wing tip attach holes to #30 and re-clecoed.  All looks great now.

I spent all day on these.  Can’t believe it took all day.  about 9 hours
