Co-Axial Helicopter is too easy... any other choice?
Yes, we recommend you the Walkera Master CP Mini Helicopter
Master CP is a small size Collective Pitch helicopter for outdoor and indoor flying. It is a transition model for players who have experienced on Co-Axial Helicopters and not skilled enough for the big helicopters like the 450 class. The Master CP has a few things that is beneficial to beginners; the 6-Axis Gyro which helps you to stabilize the body in all kinds of situation, including mild 3D aerobatics; the elastic plastic parts like the Rotor Blades, Rotor Heads, Body Frame and the Landing Skids, they can absorb some damage during crash, so you get less chance of breaking them; and the Master CP flies incredibility stable and it is a "Standard" RC Heli, I mean you can learn "Useful" and "Standard" setup skills like the "Pitch Curve" and "Throttle Curve" on this little bird without paying a lot of money, I think this is very important! For players after Co-Axial Helicopters, we recommend you the Walkera Master CP, it will help you to gain RC Heli knowledge in the "Correct" way.
