Hello, I had an idea I would like to share with anyone who may be interested. I have for years now been making small simple projects using PIC microcontrollers, and I think I have thought of a simple, feasible means of building a failsafe, with as many separate programmable outputs you may need. The PIC would measure the pulse width of each servo during programming, save them, and output those timings as soon as the Rx's signals become absent. Two buttons, one to cycle through the channels, and one to save the current position for that channel. The servos position is set via the Tx, and held while the "save" button on the failsafe is pressed. An LED will indicate the current channel being programed. I have never seen or used a commercial failsafe before, but I intend to use one for my FPV ambitions. The actual simplicity of this project makes it too tempting to resist. If there is enough interest in this, I would love to put it together for everyone else to enjoy. Let me know what you guys think!
