FLAP HINGE PIN - Vote remove middle lugs or end run through aileron bracket.

[jackking123]

What say you true me of genius. I am leaning towards removing the three lugs, one lug on hinge wing side and two on hinge flap side.

 

[Jonnyb]

I removed the lugs on my -8

 

[Carl Froehlich]

Tried both ways. Hole in the aileron bracket proved superior.

Really. OK my question is this, with the pin going out the aileron bracket (aileron push rod disconnected and aileron rotated out of way or removed),
how do you secure the pin from walking in or out?

I assume it can only go in and out from outboard end through aileron bracket.
From the plans they imply the hole in aileron bracket will not be perfectly aligned blocking pin from backing out in outboard direction.
However what do you do to keep pin from walking out inboard end. Crimp one lug?

All three of our RV’s (including the one built by Mike Seager with factory consultations….) have the two pins from teh middle of teh flap and teh Rocket will be teh same way. Plenty strong, easy to secure, easy to remove. I tried teh hole in the aileron hinge when I built teh -8, hated it, and removed a couple of hinge lugs.

Middle. I added a #6 nutplate then used two eyelets sandwiched together with a #6 screw to hold the pins.

On the aileron hole, I put in a small self tapping screw with a dab of locktight. On the flap hinge inbound end I drill a 1/16" hole in the last eye and insert a piece of safely wire.

I’ve done 5 of my 6 RV’s with the pin split in the middle. On my latest (and last) RV(6), my pin is inserted/removed from the inboard end, with the pin secured with a hinge eye. It’s very easy to install or remove.

Thank you for the replies....

Well Scott now you gone and done it.... confused with two choices now I have three... Ha ha. That is slick. Thank you for that.

I removed 3 middle lugs (eyes), used a bit of 1/4" OD pitot/static polyethylene tubing to secure the ends together.

The real question to ask is which hinge material to use -- AN257 rolled hinge or MS20001 extruded hinge

Set screw collar...very small ones, available at McMaster.

RV 8 and insert or remove from the inboard end. I use a drill to insert or remove easily. 1/16 inch hole drilled in out board end and secured to an eyelet with safety wire.

 

[Kyle Boatright]

I have one of each flavor on the RV-6. I don't have a preference. In the 24 years since I completed the airplane, I haven't touched the hinge pin(s) on either wing.

The inboard pin contacts the side of the fuselage and that prevents it from sliding out in inboard direction.

The outboard hole in the aileron bracket is secured with a split pin (cotter pin) through the hole to prevent the pin from backing out.

I went with rolled, what comes in kit. I did not have a problem with flap hinge, rolled one, on my RV-4 after 1000 hrs when I sold it.
I do love the extruded hinges. I am sure that is a viable upgrade others have done.

Hole in aileron bracket. A small rectangular 0.032 plate riveted to bracket normally blocks the hole and riveted tightly does not easily move to expose the hole.

 

[Bavafa]

I did at the aileron bracket with the hole every so slightly offset so it can not come out. I never removed it but I believe removing would have been much more difficult so if I ever have to do that, I will follow the plans and will remove from the middle.

I have no reason to think that either method wouldn't work fine.

On my 7 I split them in the middle simply because sometimes it's harder to get one long pin to feed through a piano hinge than two shorter ones. It took all of about 20 minutes to throw this setup together.

My -7 has the flap hinges like this. I like to chuck up a straight hinge pin in a drill and spin it while pushing. When you have clear access to an end. A straight pin with a drill is way easier to remove or install.
