Default Quality of build / best practices

One of my friends that is a serious RV Flyer that wants a new RV instead of upgrading his RV sent me this photo of an RV he was looking at purchasing.



Click on Thumbnail to enlarge.

This one simple photo brings up lots of questions about the build quality of this aircraft.

Yes this one photo makes me question what will be found when looking at everything on this airplane especially stuff that I cannot see.

Had less than $1 USD been spent of three (3) additional parts used in assembly of this aircraft build, I would feel a lot better about what is going to be found looking over the rest of the aircraft. I would not expect to find something like this on an RV that is trying to be sold at very high price.

Seeing this one photo, I told the prospective buyer to run don't walk away from the airplane at the price the seller was asking.

Yeah, I'm missing something here too. Perhaps an extra set of screws/nutplates on the trim actuator cover? Maybe? But not having the plans on-hand or knowing what model I'm looking at, perhaps this is per print?

On second glance, perhaps jam nuts on the thread rod, and a washer on the clevis pin?

Edit, got beat...

- Not build according Vans plan.
- Ricet spacing and how the rivet are set on the tab attachmet.
- Missing washer by the cotter pin.
- Paint on plastic parts ... solvent may be affect the strengh of it (just dont paint it)
- Looks not used at all ... rod will scuff on skin (bad design by Vans).
- Two holes in the rudder skin!?

Interestingly the plans do not show a locknut on the pushrod end.

The aft two screws are too far aft. Perhaps one of the platenut rivet holes was used as the screw hole?

The location of the removable panel is a little inboard of standard and the trim tab horn is different, showing that this probably was a later modification to an early kit adding the trim removable panel.

Is it an early -6 model?

Added - Vans plans drawings are not really complete in this area. Does a normal kit buyer get these instructions from Ray Allen for the servo installation?

http://www.rayallencompany.com/RACme...onsT2andT3.pdf

Yes, two washers and a lock nut are needed at the clevis end, however if the builder simply looked at Vans drawing 5PP I can see how those parts would get overlooked.

Yes the painter got carried away, but I saw a RV-10 done by a good shop that painted the baffle material attached to the lower cowl inlet. Painters like to paint everything.

That is the FIRST thing that I see.

The odd spaced rivets on the pivot attached to the trim tab, and the pivot is not tight to the trim tab. The last, lower on the picture, screw is miss aligned to the dimple in the trim servo cover.

The rivet thing would be the one that turned me off, but the combination says to look closer at other areas.

edit-this trim servo is located farther inboard than my 7. I has a foot on both sides of the pivot lever riveted to the trim tab. Is this all wrong or is it a different design on other RV models?
