I'm building a "new" ship from an old fuselage. I know the airfoil, chord, etc. I am in an quandry as to the joiner construction area.
What I want is an "standard" size aluminum tube joiner (probably from Gator R/C) that is straight. I don't think a "pre-bent" joiner will go through the fuselage due to width (but willing to listen). Right now 7/16 (9/16 with phenolic tubes) X 8" is about as big as I can get, assuming a 3 degree dihedral per wing panel (6 degree's total). I have top/bottom spruce spars (36" long) with shear webs as well. I feel that this is too small of a joiner. Almost forgot the span is 4.5 meters. Wing is to be covered in Obeechi. Weight will be "average" (whatever that means). I would like the plane to be strong enough to be mildly-aerobatic. Looking for input, 1) reduce dihedral (plane less stable, but what do most scale ships use) to 4 or 3 degrees total? 2) remove spruce spars and go with root rib/sub rib and add CF unidirection (full-span)? 3) go with a pre-bent joiner tube? 4) switch to a CF rod with approx. 7/16 dia? Steel rod (weight consideration **)? 5) switch to a glass laminate instead of obeechi? (really would like to stay with the obeechi) I realize that there is no one "correct" answer so I really am fishing for ideas/experience here! I really would not like to have $300 in the wing by going with full chord/span CF/Glass. +Stan RCSE-List facilities provided by Model Airplane News.
