3 ch foam plane rolls hard when turning

Hi iv just built this foam plane from dollar tree foam its a 3ch with a 40'' span and the fuse is 27''

Im having a prob with it wanting to roll pretty hard and nose down when i turn is this a lack of dihedral or something else any help would help

Yes, I also think it's a lack of dihedral. You'd get a better explanation from the gurus on the science forum

You want it to roll dont you? Or is it a uncontrollable roll? No dihedral and it would just spin in turns. The dihedral helps the plane to bank so it sorta simulates an aileron turn. Is this beyond a slight banking?

That v-stab is way too small. give it about twice the area and you'll be good to go.

v-stab stands for Vertical stabilizer which the rudder is part of . Anyone else think 2.75 might be a little to far back ? did you use a calculator ?
