Torn rx wire used to be quite common due to lack of a proper mounting system; these days people largely use the traxxas BL erevo/ emaxx mount for the MMM, which has a spot for the on/off switch too; the esc and switch cannot be separated so no more torn wire.

In any event, I woud stick the on/off switch to the esc case & wrap a zip-tie around the esc too- the case is made of quite flexible plastic so does tend to pop apart in a crash or bad/ heavy landing.
