I'm having success with wet servos, yes--though I can't tell yet how much of a lifespan to expect; I'm just planning to replace my servos (reappropriated r/c car motors) on a regular basis.

I think Turbobearcat posted on using tool dip: goop you dip your tools in to create handles. I'm just using silicone caulk.


>had lots of bouyancy so i had to use this 2 in diameter prop for a tiny 4.5 volt rx. It moved at about 3 knots.

In that case I tend to try weighting it to ride lower, or removing as much material as I can from above the waterline to reduce the 3-d "footprint" that surpasses the sub's weight when a dynamic diver takes the plunge.
