Still progressing on my build.

I’ve been working on the flight controls and ran into an issue with the flaperon mixer and was looking for advice.
When I went to mount the mixer assembly in the fuselage, it’s out of alignment - enough that when one pivot bolt is slid in the other side will not slide thru.
Anyone else had this issue - or know of a fix?

Good side


Bad side



Also the manual indicates to safety wire the castle nut and bolt to the flap bell crank— is there a special way to do this? I looked in AC43.13 but nothing similar jumped out at me.

Any help would be great.

Dave.

That does look to be a bit far out eh? (trying to speak Canadian there). If it were me I would send that pic to Brandon at Kitfox and ask him. Certain he has seen this before and knows the fix.

Here's how I did the safety wire for the nuts.

I appreciate the Canadian reference!! All good!

Ya the miss-alignment is dejecting as it really took the wind out of the sails so to speak. I have sent an email to Brandon, so we’ll see what he says.

As for the safety wire— thanks for the photo. What’s the tape? I get that is to keep the wire from cutting through the powder coat, just curious of the type of tape.

Thanks again,

Dave.

I like the tape idea-will add it to mine. The safety wire is to prevent the bolt from rotating, but it will move slightly as the assembly moves back and forth. Over time the wire could chafe into the powder coat.

Here is how I did mine. Also I believe that I’ve read somewhere that the factory now uses cotter pins. Not sure…

It's self-vulcanizing silicon tape. Where I safety wire or where I tighten down the strain relief on electrical connectors, I cut it in half and wrap whatever just as you stated; keep it from rubbing through. We called it "F4 Tape" in the Navy.

Thanks for the photo Ben — very elegant solution!
I’ll ask Brandon about the cotter pin when I talk to him about the alignment.

Thanks for the link in the tape— I’ll keep that in mind. Sounds useful.

Same kind of tape is sold by a company that calls it Rescue Tape.
