Does any one has a problem about the futaba 4px? today I've noticed that my 4px did not work properly like after I run one of my onroad cars in the track, I wanted to turn off my 4px transmitter but it won't turn off. And I tried to push one of the buttons but it's still not working. What I did is to disconnect the LIFE battery from the transmitter and few seconds I connect it again to the transmitter. I tried to turn it on again and it works, I don't know what's going on or happening to my 4px it's acting weird it looks like a computer that it hang's and need to reboot.
