If a model is flying so slowly that aileron reversal may occur and one wing stall, then it is flying too slowly, and using the rudder will equally flick it into a spin.
Absolutely not.
I agree with every word you say, Harry, about full size aircraft but, and here's the point, we aren't talking about full size aircraft.
You know how taking off and landing is generally more difficult with a 30 size compared with a 60 size? Well, that difference is continued up to full size, making discussions about full size aircraft actually dangerous for beginners.
It's as simple as this:- If you fly too slow ( a common beginners error) when landing, and don't know that the rudder can be your only savior then you will be taking a trip back to your building board for a few hours.
Try landing a 25 size warbird, Harry, and after that, tell me you don't get near snapping due to tip stalling encouraged by using ailerons.
Back to the original message . . Yes! keep using the rudder and you reduce the risk of crashing a lot.
