We had fun putting this video together to show the folding wing option on our STOL CH750 prototype plane.

That shows to go ya,

Considering the extra cost,  extra weight of hardware,  Don't go with the folding wing option...

Click on the little  i  in the upper right corner of the video.  It tells the company view on folding wings.

I had an Avid folding wing airplane for many years before building a 601 XL-B.

Folding wings  had issues even tho Dean Wilson was a Great designer.

One:  fuel in wing tanks.  Had to drain before folding....

Two: When wings were folded the tail was extremely heavy.  I learned to unfold and fold the wings on the trailer so it was easier to handle the aircraft.

Step one was to drain all fuel from tanks.  " A pain "  Then put the airplane on the trailer.

And then,,,,,  fold the wings......

Finally rented a hangar....   Expensive but a relief to just go to the airport and fly...

Oh,  Avid also had automatic control hook ups.

Basically I am trying to say.   Folding wings suck.....

This is not the reason I'm building a ZENAIR 750.I already have a plane with the folding wing option. It takes one man 5 min. from trailer to flyable. I needed a plane with a higher gross and lots more baggage area. thats where the 750 really shines, hope to be enjoying it soon.

The problem I see with this is that you cannot load it on a trailer at this point as the wings would drag when you go up a ramp. I guess you could make a cradle that goes over the aft fuselage which can temporarily hold the wings wide of the horizontal. That way the wings could stay higher. Then you could get it on a trailer and then complete the wing fold. Also, I would think the wings need to be supported by the fuselage. Looks like they are wheeling along on a dolly. So how would you secure them to travel on a trailer?

I've seen this video but do you have another video that demonstrates a fully completed plane with the bubble window/doors attached? This video shows the disconnection, reattachment and folding of the wings from a plane with no doors. I know care will need to be taken with the bubble windows when they are on and wonder if they will fully fold back when bubble doors are on it or if there is a major risk of scratching the plexiglass or paint. Do owners of folding wings do any post preparation with external padding or with soft bumpers to prevent this?

how long does it take to do it for one or two person?

How much care needs to be taken with the folding wings on a CH 750 when you have the bubble windows installed. It looks like you could scratch those windows with the wing root if you aren't careful since they stick out...what?...4 " more than flush windows?

You are quite right. Thank you for the clarification.

Kevin - I think you're confusing the 701 info with the 750. This video shows the only ("production") system for the STOL CH 750. For the STOL CH 750, the wing pivots by the rear spar area and "folds down" (as shown in this video clip), while with the 701 the wing pivots by the main spar area and "folds up"
