Another milestone day. Got the wings out of the Barn and moved them to the hangar. More photos in my gallery.

Yup! gonna put it together and adjust all the linkages and re check the incidence making sure the struts are all correct. I did this once about 15 years back and there is stuff I don't remember. Have to clean them all up real good and get another coat of varnish on and add leading edge skin and aileron wells. Thinking I may weigh it before covering the wings to try to get a feel for where the weight and balance is going to work out in case I need to make any changes.

I think that can be arranged. I've got the aluminum leading edges formed so that will be included.

Here's a little twist on leading edges; on one of the center sections we built we bonded foam between the nose ribs and contoured to shape. Then after sealing the foam, bonded 1/32" ply over the foam to form the leading edge. Made an incredibly tough leading edge.

"You mean I gotta tell you mine before you'll tell me yours?!"

haha, yep.... no tips, i didnt mold the ones im going to use yet. i didnt have the aileron on either. the top wings were a couple of pounds lighter with no linkages or wingwalks. neither have the aileron cove. guess i could spill the beans....


upper wings, 33.4 lbs each
lower wings, 36.8 lbs each.

Here we go;
Aileron weighs 4.25 lbs
Center section 22 lbs
Aluminum leading edge .020 material is 3.25 lbs
I have the leading edge listed separately as they are not on my wings yet.
Top wing with aileron hung, 31.25
Lower wing with aileron hung with all linkage except inboard push rod, 35 lbs
My wings also include the wing tip bow and an extra rib.

So my top wing in the same configuration as yours other than the tip is
30.25 lbs.
Lower wing would be 34 lbs.

None of mine have aileron coves and both bottom wings have wing walks.

Neil,
Looks great. By the way, is that just a single bungie on each gear leg? Is it normal just to have one during construction and install the others later?
best regards,
Brad

Actually the bungies that are on there are broken. What you can't see is the cable that is fitted that holds the gear at the present position.

One on each side will however hold the airplane up.

Had a chance to get some more photos of the wings today. This is a shot of the re curved center section bow. Balsa wood was used to fill in behind the spar on the center section.

The lower slave strut attachment was moved so the strut would be vertical instead of pushing at an angle on the bearings.

The landing wires and rear flying wires tend to clash on the Acro II. By off setting the landing wire anchor pin to the rear1/8" and the flying wire anchor pin forward 1/8" the wires will just clear.

Yeah Chris, the Glasair with the 4 blade is supposed to be ready for Reno this year. It has a built up 540 with twin turbos and a lot of carbon fiber ducting on the inter coolers and a custom Hoffman prop. It belongs to a guy from Australia. He is supposed to be here tomorrow to work on it.

Neil, Great looking wing tips. Nice touch with the balsa. Makes my foam and glass look like bowling pins. A little off subject, but how do you make the great looking trim piece around the windshield? I assume its aluminum. My windshield is just screwed through the plexiglass flange to the sheet metal. Ug. Garry

Thanks for the compliments.

The flanges are really pretty easy to make. Look over in "Handy Resources" and you will find "Windshield Flanges" and just down from that you will find"Windshields and How to Form Them". These are both from the Acro Sport Newsletters and they describe the process I used to make the flanges and the windshields. The method actually came from an old article by Lou Stolp in one of the Starduster newsletters.

All the newsletters we have available on this site are a great source of information. Sometimes takes forever to find just what you are looking for but the journey is fun.
