I believe that the coax's are a great learning tool. It takes time for the eye-hand coordination to sink in and learning which way you need to move your fingers when the heli does x takes time. Will it teach you enough to be a perfect flier of more advanced birds, no. The only draw back to these coax helis is that they are inherently stable, while the bigger single rotor birds are inherently unstable. But they do make for a good starting point, just dont expect to transition from the coax to the cp birds in one giant step.
