Re: [RCSE] 1/3 ASW-20 by Dream Catcher/Mark Smith Info Needed

Thanks George, yes I have thought about that. I am pondering though what thickness the cores are designed for. 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
