Hi Bill,

  

 I was lokking at how you attached the wing root  fairings and can figure out what you did on the fuselage but how did you attach  the fairing onto the wing?

  

 Cheers

  

 Mike

The fairing is NOT attached to the wing. The wing  will flex and has to be removed/installed. It just sits on the wing  surface.

Wing root fairings are bonded to the fuselage and not the wing.  When you remove the wing, the fairing stays with the fuselage.

Not necessarily. 

 I bonded my route fairing to BOTH the fuselage AND the wing. After it was cured, I then cut it in half with a thin saw blade. 

 The end result is a VERY clean joint.

Hello John, Where did you put the cut line? Do the cut edges stay pretty 

well aligned? Any tape used?



Thanks,

Thanks Bill,

  

 I should have been  a bit more specific, I was  refering to the bottom wing root fairing that you slide into the slot you built  up under the fuselage. Does this also "float" where it covers the wing and does  it fit into the joggle at the inner edge of the underside of the wing? If you  don't mind could you also explain how you constructed the slots on the  fuselage.

  

 Thanks

  

 Mike

Okay, that is a different story.

  

 First, to make the 'slots':  I laid a long  straight edge (4' aluminum ruler if I recall) down on a flat table, laid a piece  of poly over that so nothing would stick, and then laid a strip of 2 ply bid  that went from the table up over the ruler to make a step. I put peel ply over  the BID, and then brushed it down to make it conform over the step.  After  cure, it was trimmed to size, and then bonded to the bottom of the fuselage  using Aeropoxy 6228 and clecoes.  I then filled the bottom of the fuselage  at the 'step' to smooth the transition using MICRO.

  

 The fairing is attached to the wing with screws and  nutplates, overlapping the 'joggle' and it 'floats' in the slot on the fuselage,  that way there are no stresses when the wing flexes.  At the front of the  wing, the fairing tucks under the top fairing.

Thanks Bill,

  

 I really like your solution and if you don't mind  I'm going to copy it.

Actually we should give credit to Bob Anderson, he  did it first and I copied HIM!!

Hi Bill

  

 I presume you did a layup and used the bottom of  your wing as a mold to make the panels for the bottom wing root fairing. What  did you use as a release material and how thick did you make this  layup.

  

 Thanks

Actually, the close out panel was supplied by KIS  as a molded part (flat with curve for wing leading edge) as a single sheet. I  had to cut it down the center and then make the curved cut to handle the  transition at the front.

  

 If this was not supplied, you will have to make  your own by covering the wing with 2 mil poly, then making the layup over the  poly, using peel ply. The factory piece looked to be more than 2-ply, I would go  with 3-4 ply for that part.

Hello Mike, When I made these fairings for my KIS TR-1 I set the fuselage 

upside down, installed the wing (one piece wing for this plane), and molded 

the fairings to fit exactly. I used primarily package sealing tape for 

release material and to bridge the gap between fuselage and wing.
