How waterproof? Ive never had a servo fail on me. Snow, mud, wet grass. Are you going to submerge your truck? I have a nice airtronics HT MG servo. Its digital and is 190oz @ 6v. Or I could sell you a TRX2075 for $15 shipped. I have several. I think there good servos. 125oz/in and decent speed. PM me if your interested in either
