From some research I did a long time ago, I decided if I built another
plane I'd add about 50% more dihedral to improve the roll stability.
This is because although both my KRs are stable in pitch (it will
automatically recover from a nose-down attitude by bringing the nose
back up by iteself), any tiny upset from straight ahead and it will drop
off either left or right and continue into a dive (or maybe a
spiral....I never let it get very far).
See https://en.wikipedia.org/wiki/Dihedral_(aeronautics) and

for a quick lesson.
