just leave it.....if you have installed it correctly with spacers inside the wing, it aint going anywhere! ....if not, JB weld or solder a washer on it.....

I would also put a ply brace a bit bigger then a "button" on there.

Rather than just a "button" on the post, I like to use a triangular piece of 1/8th ply top and bottom with the post going through the apex of the triangles and the opposite flat side up against the inside of the fuselage side. You now have your plywood support epoxied to the post, the centersection sheeting, and the fuselage side...

I totally agree with Ward!

Use a piece of ply wood that will go over the post AND connect to the inside of the fuselage on the top and bottom.  You will destroy the entire plane before the BC post pulls out!  

I use a piece that is abut 1 1/2" wide where it hits the fuse side, and 1/2" wide where it goes over the rod. All gets epoxied to whatever it touches.

EDIT: Do this final support after you attach the wing to the fuselage.  Then lay a fillet of your choice all the way around the interior of the fuselage/wing joint.  Epoxy and microballons is good for that, it doesn't need to be more than an 1/8th to a 1/4 inch fillet.

Would some body cut into there plane and take me a picture?


No wait... I think I might understand it...

Stay tuned.

Hey Jim,
You did put the instructions in and it all fell together. Some one suggest "the apex of the triangles" on the post and so on. When someone uses 20 dollars words is throws me.

Hi Paul,

A *little* late, but I remembered this:  I Dremel off the rods flush with the ply so they are not sticking out, then epoxy a small piece of ply over the rod ends.  That makes it doubly sure that it cannot move up or down.  A *touch* of weigh, but it's near the CG and I just like the *security*.

Bill, I like your idea for sure and weight is important but near the CG like this, I wouldn't worry either.

 I have a picture of a friend's bell crank with a simple Zbend.  Held up pretty good it seems. Have a look and judge for yourself. A picture is worth a thousand words!

That looks like a PERFECT bellcrank! Made of Jello, I believe! Never use a perfect bellcrank on anything over an .010 airplane!

Hi Robert,

The Z bend will hold fine, but look how much it hooged uot the BC!  The hole is twice as big as original.  A piece of brass tubing in the hole (and the cable holes, too).
