260 Flyer Posted June 10, 2008 Share Posted June 10, 2008 As always if it looks right, it will probably be OK. For a general sport model about 6 to 8 degrees total (3 to 4 deg under each wing) will be good providing the the tail plan-form and moment appear to be in normal proportions.A converted free flight vintage model with 10 deg dihedral can be a bit snappy on the turns but looks positively wrong with any less dihedral.

Ernie Posted June 10, 2008 Share Posted June 10, 2008 Hi Guys, Last Saturday, there I was, sitting on a French beach, With a spitfire hurtling towards me (a real one) and of course it has dihedral. Surely, the last thing a spit needs is stability, so, why?ernie Quote Link to comment Share on other sites More sharing options...
260 Flyer Posted June 10, 2008 Share Posted June 10, 2008 "Surely, the last thing a spit needs is stability, so, why?" The Spit needed neutral stability and without the dihedral to lower the effective centre of mass it would prefer to be a high wing monoplane.They even built in 2 degrees of washout to stop it droping a wing on tight turns!
