Indeed. I had a rudder and elevator only model with reasonable dihedral.
That would spin nicely and even flick roll.

A model with only rudder and elevator can also do surprisingly steep 
turns.

I once one a club competition for the most number of spin turns in 2 
minutes from take off. The model climbed fast entered and exited spins 
very fast and with an extra climb in the middle I got around 50 turns as 
I recall. That one did have powerful ailerons but they did not come into 
that flight except for the start, middle and finish. It had no dihedral.
