Complete lockout while flying
I just got an email from Futaba saying that the problem is switching the CH. 51 crystal to 56. They said that the receiver was tuned for the 51 and reduce range came about on ch 56. My manual says that you can change the crystal as long as its in the higher band. Now I am confused? Any reason why the FP-R148DF receiver would be different and need to be retuned when crystals are changed?
