Kadet Mark 2 Wing Ribs
 

I got a Kadet MK2 this week, and it's missing the sheet with the four "W1" wing ribs. Are the W2 and W1 ribs the same shape/size? I have some balsa to cut the ribs out of, but there's no drawings of the parts on the plans. Is the only difference the size of the cutouts for the spars? I emailed Sig to see if I could get the parts, but figured I would try to make some in the meantime.

The manual isn't real specific about the differences in the types of ribs. I'll just cut them out from the other type. Thanks

I have never seen or built this kit but in most kits the #1 ribs are 1/16" smaller to accomodate the center sheeting.

The K-Mk2's general rib profile differs only in the width of spar notch and tiny LE/TE shortening to account for any LE/TE/spar doublers. The wing is flat bottom, constant chord and thickness out to the wing tips. With a sheeted and cap stripped wing of this type, the profile of all the ribs will wind up being very similar.

If you have one rib, you pretty much have what it takes to generate something workable from.

Consider recutting any ply in your kit if its fairly old. A K-Mk2 I built recently was early 80's vintage and the plywood was de-laminating in spots. I recut all the ply parts from fresh stock.
