Looks like mine is faulty. I connected pin 5 Flip input to pin 6 ground. Ive tried it with a normal switch too and nothing happens to the motors. Maybe I could check your set up at the next live event I can get to. Theres no jumpers to set are there?
Yes I agree it would be better to use a third channel but I dont have a spare. Perhaps I could feed the tilt activated signal through a short delay (probably use a PIC) to eliminate faulse alarms/bounce etc.
