Posted: Sun Dec 16, 2007 5:07 pm Post subject: wing tip

I'm about to fit the wingtips to the wing, and I  need to determine the neutral aileron position to align and trim the length of  the trailing edge of the tip with the aileron. Does the neutral position that is  set with the rigging of the wing bellcrank give a true neutral, or does the  aileron need to be set  to trail with the flap for a  accurate neutral  position? On the RV8, I had to wait until the wing was mounted to the fuselage,  install the flaps and rig to full up, then adjust the aileron trail to the flap  trail to get a true neutral. Am I better off waiting until this scenario on the  10 as well?

On my 6A, I had an airfoil template that I used for  the ailerons, flaps and tip - even prior to inatallation of the wing to the fuse  - and it hasn't needed to be changed since I installed the wing.

  

 I was planning to do the same  again......

Chris,   Other's will have to chime in,  especially those flying.  When I did my wing tips I used the "neutral  jig" which sets the aileron neutral position,  checked and aligned the  flaps to the ailerons and then set my wing tip trailing edges to the  ailerons.   I believe I had the "old version" of wing tips as they  were about 3/4" longer than the aileron,   but none the less, I had to  cut the upper and lower wing tip surface at the trailing edge to pull the wing  tip into alignment with the aileron.   I used a long straight edge to  align the wing tip to the aileron and used it as a clamping jig while the resin  dried.  I remeber cutting about 3" forward from the trailing edge  to give the upper and lower tip skin some compliance so I could easily  align it with the aileron.    When I was done it came out  swell.      

  

 Here's a picture when it was all done.

I would get it all in the wing rack and get the flaps installed

so they're all the way retracted, and then align the ailerons

to them and then mount the wingtip so it aligns with the flaps

and ailerons.  That way when you're in cruise it's all lined

up nicely.  If you just did it rough now, chances are it won't

be aligned well later and you may end up with the famous

"droopy aileron" syndrome have to deal with that later.

I just got off the phone to Vans, and was told that the rig on the 10 is to  put the flaps all the way up against the hard stops at the rear spar, which is  the reflex position, then rig the aileron to trail with the flaps, then the tip  to the aileron. The bellcrank jig is used only to center the bellcrank, not to  rig the aileron. Thanks to all.
