I have a 46 size with a Saito 100 in it and I have yet to have a problem with tip stall. Understandly it is overpowered but I can land it slower than a person walking. I'm not particularly a good pilot but this is a piece of cake to fly. IThe plane is so stable in a no wind situation. I can set up a landing decent and not enter a flight correction untill flair.
I don't have a lot of airplanes but this is the most fun to fly.
K.O.
