So, let me make sure I am understanding you correctly. The only way possible for me to have lost bind with a plane or planes is if I inadvertently depressed the bind button during switching on of the transmitter? So if I had the transmitter laying on its back and switched it on, pressing down on the transmitter it would be possible I might have pushed down hard enough to activate the bind button therby losing bind?
The switch going bad or providing improper voltage didn't cause it to lose bind with the reciever, just prevented from linking up with the reciever, until I got the proper voltage to the reciever?
