I bought a set of the Plasti-blades for the CP Pro and tried them on my Axe today. I had to mill the molded boss down so that they would fit in the grips. They are a bit shorter and the cord length is shorter as well. They don't generate as much lift as the Stock Balsa blades, and I think they are much heavier. I also replaced the stock Axe paddles with Blade parts becasue They lock in position better than the Heli-Max parts. The combination was almost unflyable. Control inputs were seriously sluggish and unpredictable. The CP Pro paddles are just a bit smaller than the Axe paddles, but the locking screw and nut probably make them heavier. I have a nice scale; I will weight them tomorrow. Anyway, I am going to go back to the 14.5g factory blades coupled with the Blade Paddles, and see how that works.
