Please help me to understand what exactly CCPM is for. Is better for sport flying and 3D? What are advantages and disadvantages?? I am using Futaba 9 CAP; can I fly heli w/ CCPM??? I am asking all this because I want to get the JR VEnture 50 w/ OS 50 engine. Is it good heli to lern 3D or should I be looking for something else?Thank you in advance.
