None of the servos will move on my 450 heli. Everything was working, and I hovered the heli for a few seconds the other day. I stopped because I was getting lots of wobble in the rotor disk so I took it home to change the mechanical setup. I moved the ball links in far enough on the servos that I could use all of the throw and still get enough cyclic throw, then fixed the trims in the ZYX programmer and the pitch settings in the transmitter. I went out to fly again yesterday, and I saw that the tail was now reversed. I switched it in my transmitter and used the bluetooth programmer to fix the compensation direction, and when I exited out of the program on my phone no servos would work. I tried unplugging the battery and restarting, and I tried going back into the settings and exiting again. Everything looks right, and the rotor would spin up so I know I have power and a working receiver. Are you guys aware of any issue that would cause the ZYX to not work any of the servos? Or maybe someone knows who to contact for customer service from the manufacturer?

Strange... Try doing a factory reset with the sticks and lights method from the manual and then reload your configuration file.

do you have analog servos? could you possibly have set it for digital and burned out the servos?

I'm using the Henge Digital servos that come in the big combo, so it's not that. I'll try doing the reset. I can also do that through the bluetooth controller. Does it make a difference?

It's the Henge digital servos that come with the combo, so there shouldn't be an issue there. I'll try doing the reset and see what happens. Isn't there an option to do that from the bluetooth adapter too?

Ok, doing a manual reset and starting over with the configuration worked. That's really weird and gives me the heebie jeebies, but at least it's working now. Thanks to those who helped. I wouldn't be able to do this hobby if it weren't for the online forums.

Necropost. Mine just did this to me too. Looks like yours is still working? I'm really freaked out that it might happen in the air.
