Well, after wreno and I chatted online a while back about waterproofing and he pointed me towards some servos that are spec'd as waterproof, I figured I'd give them a try (always loved destructive testing, and I run these experiments so you won't have to). So I ordered up a standard bluebird servo advertised as waterproof (I was highly doubtful). I just received the servo today and dunked it in clean, fresh water to a depth of 1" and then set about running it back and forth, not loaded. It ran fine underwater for about 5 minutes and then it started showing the jittery/jumpy servo syndrome indicative of water getting into the pot. So the short and skinny of it is that the servos are NOT waterproof. They are definitely splash resistant but that ain't waterproof. have fun folks. -Greg
I probably should have mentioned, that while not waterproof, they did seem a bit more water resistant than other servos that I have played with, which probably means that they are a decent servo to use for our purposes. -Greg
Probably just fine. They even have a nice smooth seat for the O-ring, however their servo horns are really really sharp and will slice into the O-ring. You would need to buy Futaba servo arms in order to seal well (or even better some of the futaba spline after market heavy duty arms so that the sealing area is increased.
