Maybe it's just the picture making those hinges look fatter than the ones I used. Lengthwise you'll be fine cutting them down as long as you still have a couple of barbs inside the control surface to grip onto that epoxy with. Obviously you should keep them as long as you can though I used a drill press when I was drilling the holes into the ailerons so that I could get the holes as deep as possible without puncturing the surface (it's a little tricky as the ailerons are tapered, so take your time and be careful when you're doing it. I would also strongly recommend making a drilling jig for the ailerons/trailing edge so that you guarantee hinge alignment.)

No, they're the wrong ones. They're almost as fat as the ailerons are thick. And I think they're actually fatter than the tapered part.
I'm going to take them back and swap them on my lunch break.

Yeah, those are definitely the 'Super' hinge points - they're 3/16" diameter instead of 1/8" which is what the standard hinges are. You can see the full line-up of Robart hinges [link=http://www.robart.com/Hinge.aspx]here[/link].

Think that hinge point drill jig would be a good idea to get? I won't have access to a drill press and sure as $@## ain't gonna buy one.

I made one myself. Just get a piece of wood the same square as the trailing edge of the wing (I think it's 1/4" square, although it may be 5/16"... it's been a long time since I did this so you'll have to check the plans to be sure ) Measure the points at which you want your hinges, then drill through the length of wood dead centre vertically, being sure to keep the holes perpendicular (this is what I used the drill press for.) You can then drill holes in the trailing edge and aileron by carefully clamping the jig onto the piece, then just using the jig's holes to guide your drill bit.

Cheers,
Neil.

Hmm... definitely gonna have to get a drill....

Also taking a 4 day weekend this weekend to build...

Let us know how it goes, and have fun!

Even though Hinge Points are my favorite hinges, I normally won't use them for strip ailerons because it's too difficult to install them without drilling through the faces of the aileron.

You *can* cut them shorter, but I don't trust that too much. Bottom line is I use pinned, flat hinges for these kinds of surfaces. By pinned, I mean a hinge with a pin - not a bendy piece of plastic.
