Dihedral is solely for lateral stability. You sacrifice just a little bit of lift for stability. It sounds like you kept the same angle...and that is good. Make sure you maintain the washout...that is there to make the outboard wings and ailerons stall last...again for lateral stability.
Decalage is never "correct". You have to have downlift on the stabilizer to maintain pitch stability. The decalage is there as a neutral difference in stab aoa and wing aoa for level flight...but that changes with gross weight, cg, and airspeed. Logically a longer fuselage would drive less aoa on the stab to get the same moment. https://sites.google.com/site/mykr2stretch/ https://sites.google.com/site/mykr2stretch/parts-for-sale On Jun 11, 2014 7:00 AM, "cruzj12--- via KRnet" <krnet at list.krnet.org> wrote: > Good mornignKR builders, > I have a question about wing dihedral for all the aeronautical engineering > people here.I'm currently extending my carbon fiber wing extensions with > the 29" template on the ends.
