As far as the water getting in, if you have everything sealed properly it may be coming in from the stuffing tube. A small piece of water line over the stuffing tube extended over the flex that's well lubed should stop it. It could also come from a cracked water line that looks ok until pressurized.

So if running over 4s disconnect the red wire and get an external battery pack is what I am reading. I have a old pack from a car w 4aa batteries will that work as an external power supply for receiver ? Also I read to program it before removing the red wire is this true. just got new esc for mg and says has built in BEC but sounds like I don't want to use it. Any help would be great on the BEC questions. Thx

Yes and yes to both of your questions my escs have been hit or miss I have 3 t180s one the occur has to be manually set one the bec never worked on since new and one works perfect also my sf120 works as it should but I would get the usb programmer because its a pia to program

Instead of cutting or pulling the red pin on the esc simply get a short servo extention lead & connect to the esc plug then disconect or pull the pin on the red wire on the extention lead. If you then need to reprograme the esc you simply disconect the extention lead which leaves the original esc plug intact. Martin.

Thx any reason not to use a 4aa with switch out of old rustler to power the trans and not use a external BEC Other than weight and replacing the batteries will it do the same thing? Thx for all the help guys.

No reason. A lot of its preference. Some use UBECS, some rx packs/ 4 AA's. Just keep them fresh and/ or charged.
