Brian: Would it be better plug the cap into the Rx (glitch buster style) or as close to the output of the bec as possible? I'm thinking the closer to the Rx the better.. but I'm not really sure.
Probably would be best to have the cap close to the source of the noise (BEC), but I've always just put a short servo lead/connector on a cap and plugged it into the CH3 port on the Rx.
