Hi, I'm so happy now. I find the possible problem with problem to control the pitch controlled by futaba radio. When my phantom v2 came to me I never power on the original radio on phantom, I not plugged the original receiver, I plugged the futaba receiver. Today I tried connect the original radio and I can control the pith. Simple and complicated, because I find just this possible to resolve, all last try nothing resolved, after power on the original radio and control pith, I power off the original radio, power on the Futaba radio and enjoy the perfect funcionality.

Thank's a lot for your attention
