Frank: I still have the fuse from many years ago and I have set up a standard stick wing. Hope to fly it at WC '06 or '07. I found a good set of info on the ASW 20CLX - extended wing with winglets. I am using Dr Drela's BD wing platform for the wings, 3/16",5/32, and 1/8" hard balsa ribs (Lofted with Compufoil) with 3/16 ply ribs at selected locations, full spar width vertical webbing, and layered carbon spars. Cap rib side of LE with carbon and bottom of the TE. Aileron sub spars generously capped with carbon. Carbon wing rod and tubes. By the time you have the correct sized obechii, a proper spar built, and proper vacuum bagging set up, etc, the ribs can be cut and the wing laid up RTC. IMHO Happy building Jim PS:laying up and vacuum bagging those long wings could be a nightmare!

I have never cut cores but I know that the thickness of the intended sheeting is considered (deducted) so that after sheeting the desired airfoil shape is achieved. Or does a millimeter more or less not matter that much? It's an older airfoil anyway, FX60-126 if I remember correctly. > > > Thanks, > > Frank > ----- Original Message ----- > From: George Voss > To: 'Frank Deichsel' ; 'RCSE posting' > Sent: Tuesday, December 27, 2005 10:10 AM > Subject: RE: [RCSE] 1/3 ASW-20 by Dream Catcher/Mark Smith Info Needed > > > Frank, I'm not familiar with this particular plane but I'd agree with you. The obechi we get here in the US is going to be pretty thin on a 5M wing unless you have a substantial spar system. Have you thought of using 2 layers of the thin obechi? > > > > George > > > > > ------------------------------------------------------------------------------ > > From: Frank Deichsel [mailto:[EMAIL PROTECTED] > Sent: Monday, December 26, 2005 9:15 PM > To: RCSE posting > Subject: [RCSE] 1/3 ASW-20 by Dream Catcher/Mark Smith Info Needed > > > > Hi, > > > > I got a good deal on a 1/3 scale ASW-20 kit made by Mark Smith/Dream Catcher Hobby. Unfortunately there are no plans included and I need to know what thickness obechi the wing cores are cut for. I did some research but no success. The common thickness for sheeting seems to be 1/42 here, but from what I found that seems to be too thin for a 5 meter wing. There is a wing made by Mueller in Germany in the same size which is sheeted with 1.2 mm which is roughly twice as thick. > > > > Any info would be appreciated! > > > > Frank > > > > > v\:* { > BEHAVIOR: url(#default#VML) > } > o\:* { > BEHAVIOR: url(#default#VML) > } > w\:* { > BEHAVIOR: url(#default#VML) > } > .shape { > BEHAVIOR: url(#default#VML) > } > > > > st1\:*{behavior:url(#default#ieooui) } > > > > > > > > > > > > > Thanks George, yes I have thought about > that. > I am pondering though what thickness the cores are > designed for.
