Unfortunaly that wasn't the problem with mine. I was aware of the Futaba tab etc. The charge jacks were just molded to poor tolerances. (in fact... most of my tabs are cut off my plugs as I use a lot of Hitec stuff).
I use White Out to put a "dot" on both male and female plugs. That way I just line up the dots.
PS..... I have all kinds of extra leads and none of them fit correctly into the Ernst jacks.
....lownslo....
