Well you do live in LA Steve- not known for it's precipitation.
I've had some experience with an OTW module- the one they manufacture for the big Type VII. It was the one belonging to Paul 'Von Braun' (remember him). He attended the first sub run I organised back in '06, and he'd blown the Mtroniks controller. I stripped it down and fitted a spare esc, and he was back in business for the day.
I dunno, all that work, and you don't even get to have a play with it.
