But seriously though, Castle needs to get their act together on this. This has been a problem from day one and I have not heard a word from them addressing it in the last 6 months. I've posted complaints here twice.

I've gotten replies such as:
"It only seems to be a problem with a particular servo." Not the case. Seems to be any high power digital servo that is causing the problem and it put me back $80 to find that out.

"You probably have a bad chip." Maybe two? in each of my escs that seem to be working normally otherwise?

"A power cap should solve the problem because it's the current spikes created by the servo when it changes direction." Been there, done that. No go.

Face it, it's time that Castle takes some heat on this. They could at least be proactive and let people know what is going on. When I people who are newer to the hobby running into this problem and have gone painstakenly out of their way to pinpoint it without luck, it really gets me.
