Default My flaps are too long!

Maybe it was just a long day in the shop yesterday, but I remounted my wings so I can set up my flaps. I can’t physically fit my flaps in position. Not even close! I would need to trim a good inch off- no way that can be right.
I originally fitted my quick build ailerons and flaps according to plans while wings were stand alone and fuselage was not started. My gap spacing was set and everything riveted on. Then I took the controls off.
I have set the wing angle, sweep, etc and it is about as perfect as it can be. It just seems my flaps are about an inch too long? I’ll have another look at it today but that was a show stopper last night.
Anyone know what is going on?

Is it off by the same for both the left and right?

We're gonna need more pics. What's the other side look like when your holding it in that position? QB wings or just flaps and ailerons? Can you show some detail of the entire hinge riveted to the wing all the way out to the aileron mount brackets?

I wonder if they are RV8 flaps. My hinges look like they are about that much further away from the fuselage.

This is a good thought. My RV-7 flaps measure roughly 56.5" between the rivet lines of the inboard and outboard ribs - would be a good thing to check.

Let's confirm Mikeyb's suspicions-
RV-7 flap - width at trailing edge 58", width at front spar 56.5", inside edge should project in towards the fuselage about
1 3/16"

Both sides are the same.
They are quick build flaps, wings, and ailerons.
I can give more pics but this is really weird. Maybe they are Rv-8 flaps?!
Thanks for the measurements. I will measure and post to here this afternoon. I have an email in to tech support as well. I canít be this dumb!

Yeah, maybe.

The TE of my (uninstalled) RV-8 flap is 61” exactly. This has not been cut to fit to the fuse.

I would have loved to see the look on your face when you put the flaps on and they didnt fit. Im sure it was an interesting moment! Several times in my build I had times when I just stood there with my mouth hanging open - but they were never like this!

They must be 8 or 9 flaps. I cant wait to hear the rest of this story!
