Default Odd!

I wonder if its still aerobatic?

Also there is something odd in the rear canopy.

Do you have a link for where this is, I could not find it on BStormers.

Did he split the flap as well or does the -4 flap stop short of the ailerons where he folds the wing? What about the fuel tank?

That was my first thought too.

Wing folding mechanisms aren't really all that difficult... They do always add weight, though.

Here's the link to the ad, with more photos.

Look like the owner has used Sika or Proseal to bond in a plexi panel behind the passenger's head... Maybe stopping drafts?

It would be great if Vans could off a mod to make the RV with folding wings like the Mustang II. I like the RV better, but the folding wings on the mustange are very cool.

Default Only one wing?

The photo that's shot from the front shows that the flap on the folded wing is shorter than the one on the other wing.

I wonder if both wings fold, or only the port-side wing?

I also wonder if it has flown since the folding mod was performed.

It looks to me like only one wing folds and the flaps are definitely split, an unfinished project maybe, maybe the design intention was for both wings to fold but something interupted the project.

The cool factor is high on folding wings. As with it all there will be a trade off.

Extra weight, out bound on wings.

My first thoughts: RV4 folding wings?? It only has a 23' wingspan! Why fold them?

Fun to see the photo. Very cool.

It looks to me like both wings might fold. From the front photo you can see that there is a break in the right flap at the same station as the break in the left flap. There also appears to be some kind of a seam in the underside of the wing at that same station. On the other hand, I don't see any seam in the leading edge...

It would not help fit it in very many hangers I know (and especially in my hanger). Would only help in hangers with all low wing aircraft. Mine has 2 high wing airplanes so the low wing RVs fit under them.

In my opinion, no way does the precieved "cool factor" ever buy its way on an airplane espeicially for something already as cool as and RV but i do love the rules in E-AB that let people try these kind of things. Makes going to OSH fun to see what others have tried (do not get to see much at OSH what others have failed trying)

This same aircraft was discussed on VAF several years ago:
