Here's a good question. How come when you stall an R/C Airplane and kick
full aileron at it you can't get a stall spin like in real planes? I've
tried it with multiple R/C planes and never have seen anyone else have it
happen. Is it a weight or wing loading issue?

Well, first off, you "kick" in full rudder not aileron to spin.
Works fine on my BobCat and Wanderer. The Wanderer has a tendency to tighten
the spin after three turns. I taught a friend how to spin his and he got so
enamored with the motion that he spun it into the ground. Bad news.


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.
