ORIGINAL: Duane-RCU Good choice for me to bail out and not finish the races that day... I decided to try to duplicate the problems on the bench, lightly tap the switch, wires, Rx, jiggle everthing. Then it started acting up, jittering, no response at start up. I got my other Optic 6 out, everything was perfect. Back to the other Tx, problems again. Touch or wiggle module, and all problems happened! So it is a module connection problem. I know there was a problem with the first Optics (cases?) but both of these are not included in the build dates that had the problems, even though they are a few years old. Now what?
