Without looking at mine I think that I did not have an AN365 in that place. If I remember correctly (and that is a BIG caveat), mine had metal locknuts called out which are much smaller than the AN365 or plastic insert locknuts in general.

I'm waiting for some half-height nuts (AN364, IIRC) to see if that permits free travel, but I'd like to find out why they are rubbing in the first place.



Thanks again for any insights!

Having a bit of trouble with the picture but, if it's the bolt I'm thinking of, I had that problem and had to flip it around and put the nut on the other side as Bob suggested earlier.

That would put the nut on the bottom of the belly of the airplane.
I am pretty sure MacPara has it correct.
The fastener in question is supposed to be a screw (head on the outside of the belly skin), with the small MS all steel nut (much smaller than the AN365 nut shown in the photo)

Ahhh, yeah, you're right - that's the top of the systems block under there ...

The throw is not reduced with the flapperons in place. The throw is limited by the flapperon mixer.

At page 31-13 you can see the hardware to be used. It calls for an AN365-832. From what I remember I installed very small all metal locknuts. The hardware in the picture looks too big.

I have the same issue. I think the flap handle is to far forward. I am continuing with the build because I don't think this is a problem. I think it will not be an issue once the flaperon control is completed.

Oh, sorry! The point I was making is that the throws are going to be different when the DEVICES are connected. I think the mixer is considered a device.

I know of instances where builders have installed the the flap handle with the UHMW bearing blocks positioned / oriented incorrectly and it does cause the flap handle geometry to be incorrect and induce some strange issues.

Default Flap pushrod

Have seen this when the flap handle to mixer pushrod are too long. If you haven't drilled the flap torque tubes, I'd try screwing the pushrod in further.

Good luck

Don't be changing lengths of ANYTHING on the RV-12. Recheck the plans. Follow the plans. Make the control rods the exact lengths that the plans say. Use the exact parts and hardware the plans say. Mantra: If something does not fit, STOP! The likelihood is that the problem does NOT lie with the kit!

And check the RV12 forum thoroughly using search. Check the blogs for that kit section like Schmetterling Aviation and Marty Santic's and Tony Tessitore's picture set.
