egh I ran mine in water to try and skip across it and on the lake in the winter, snow, etc. No problems at all. I don't use after-run oil either (got suckered into buying it at a hobby shop and then after talking with R/C guys who have been in the field for 20 years they said no way you don't need that unless you have a boat, if even that.) That was a couple years ago and finally just this spring I changed the bearings in my wheels, but thats it. They are all sealed bearings and when their new they work really well.
However I have never totally submerged my electronics.
I'm sort of a "drive it like you stole it" kinda guy and for the savage X to last me more than 2 years, summer and winter driving, thats pretty good. I don't even have holes cut in my windshield. Guy at the LHS couldn't believe it, figured I had done a lot of damage to my engine....10 Gal of fuel through that engine and not a single hec-up, I don't think holes in the windshield are that important. Same with a temp gun....I've never had one.
