Default Loooooong Screws?

I'm putting together a Powerline Edge 540. 46 size.

The aileron control horn screws are only about 3/8" long, and the thickness at the LE of the ailerons is 1". So, I need to order some longer screws.

Microfasteners only has #2 screws at 1". Nothing longer. I need 1.25" to make it go all the way through the horn and through the aileron and into the plastic part on the other side of the aileron.

I thought about just running the 1" screws in and using CA to hold them in there, but I'm afraid that they will eventually rip out of the balsa. Aileron flutter--SPLAT!![X(]

Any ideas?

Replace the horn(s) with something like this.

OR

Peel back some of the covering (I am assuming it is an ARF ) and inlet for a piece of 1/8 or 3/16 lite ply. Glue the ply in, and reseal the covering. Now just use #2 wood type screws (servo screws ).

I know how to do that, but I don't want to.

Really would just prefer a longer screw.

Yeah!! Those will work. COOL!!

I wonder why I couldn't find them? I spent about 20 minutes looking around the site and couldn't find those. Maybe I'm just gettin' old?[sm=bananahead.gif]

Thanks a bunch.

Most hobby shops have #2 all-thread. Could you cut the length you need and use a #2 lock nut on each side?

I know the all thread method too. And I HAVE 2-56 all thread here.

I just want it to be done right. I don't want it to look hacked up. Life's too short to build ugly airplanes.

I'm anal retentive, and I know it. I want everything to be perfect. Sometimes it's good, and other times it holds up my progress. Ask my wife about it--she thinks I need therapy.[sm=spinnyeyes.gif]

But, in the end, I build a tight airplane and they look nice.[8D] Nothing falls apart.

I placed an order with micro fasteners. Screws will be here next week.

Thanks guys.
