baby ring wing

The center ribs should be slightly undersized so the 1/16" sheeting will fit flush, grain going with wingspan, this will give you more strength at the joint and a place for the wing covering to stick to. I'd cover after its glued in, not that it would make a really big difference.

I believe the center section gets planked on the Baby Ringmaster. I can only remember one plane I've built that didn't get planked under the fuse and that was the Sweet Pea, if I remember right. I can check the plans tonight if you would like. As far as covering the wing, I cover the wing first if I'm using Polyspan and dope. I believe it makes the wing stronger. I cover and dope with clear and then insert the wing. If I cover with Monokote or other film, I cover the wing after gluing it in. I'll glue everything up, cover the wing, lay the fillets, mask of the wing, and paint the fuse. But that just the way I do it. Many ways to skin a cat or build a model.

Like others have mentioned it should have 1/16" sheeting top and bottom across the four center ribs.

If you dope and tissue cover after you epoxy the wing to the fuse. If you choose to monokote(or similar) then cover the entire wing and then cut away a thin strip and then epoxy on the fuse.

Done that way it makes a nice seam. What plans are you using?

Ron:

IIRC this is a "scratch built" BRM rather than a kit with plans.

I was going off of the fact he was saying "non-kit" plans. As in plans, but not from a kit.

I assume he didn't just draw something up.

Your plans in the image show a dotted line on 1/2 of the ribs on either side of the fuselage. Those dotted lines mean something is hiding the line. It also indicates where the sheeting is recommended to. You can also see the opening for the push rod in the drawing...

Yes, this is inferring the intent of the person who drew the plans, but is based on manual drawing (drafting) convention. The convention is generally carried through to CAD output, but not always.

The grain runs span wise so it will flex around the wing easily. This might not be depicted in the plan, and other than drawing grain or an indication of grain I don't know if there is a convention for drawing it.

I should have looked at the picture closer. I have built one using those plans. Sheet over the center 2 ribs not 4 like I mentioned earlier.

THANKS for clearing up some issues for me, I think I may have bitting off more than I can chew for my first build after 30+ years . should have started back with a kit model? lol I want give up thow I was just really discussed with it yesterday ! I am taking notes for the next one if this is short lived from too hard a landing that is nose first. LOOKING FOR A BETTER DAY TODAY!!

hey you're doing fine, enjoy the build....get'er done!
