RE: What Prop for Big Stik 60?
My experience has been that APC props are by far superior to MAS. MAS will take a prop-strikle better, but if you are confident in your abilities, get the APC.
APC 15X4 W will give you quicker spool-up and a lower top speed. I don't think top speed is important at all,. so I would get the 15/4 W from APC. Also, the 15/4 W will slow you down a bit better when you throttle-down.
That plane is not a SUPER aerobatic plane, but I learned to hover on a stick plane. They can do a lot more than you would think, but I could never get into a good KE with mine...probably my fault as usual.
You just can't go wrong with any prop on your list, but APC is best for performance, MAS is best for durablity. I think you should stick with a plastic/nylon prop. Wooden props in that size range are just not that great for learning new things.
