Water-Proof Servos?

[waffel42]

Anyone know of RELIABLE water-proof servos that can be placed outside the WTC without getting themselves flooded?

Savox makes some as well. I have one in my 45" fast electric

there is no such thing as a truly waterproof servo. the only servos sold today with an actual IP rating are the blue hitec that ekloss refers to, and they are rated at IP67, which means that they will remain operative in water up to 1 meter (39") deep, for up to 30 minutes. none of the other servo manufacturers list IP ratings for their servos, because they, in truth, are only water resistant, meaning they are good to go in an offroad car, and wont be destroyed if you drive through a puddle. anything else, and they won't honor their warranty. the savox website specifically states "This is a great upgrade if your looking to drive your RC vehicle in any condition...rain, sleet, or snow." nothing about putting your "vehicle" at the bottom of a pool...

buy a half dozen of the hitec, and be prepared to replace them when they fail. design the installation so they can be removed and replaced.

A few years ago I hunted down a gentleman who had written an article about waterproofing servos. He responded with that eventually they all had to be replaced and recommended putting them in a dry space and not in the wet. There may be ways to prolong the life while in the wet and I still see people filling servos with silicon and spraying components. So, it ultimately will come down to maintenance and as Tim said having extra servos at hand.

How about making a dry box for the servo and mounting them like small work model servos?
Tupperware sandwich box. Pill bottle. Otter box. Vacuum bag.

Are those all pill bottles in the stalagmite photo? Looks like a weeks worth for Dr House!

With a small through-hull seal, the pill bottles would make a nice teensy WTC.

Engle has some listed on his web site as well. Best Wishes Mike Dory

A guy on RC Groups tried the pill bottle approach, didn't seem like they were really waterproof.
