Water proof servo

[Peter A]

Grease doesn't 'seal' the shaft, but if you pack the gear case then water cannot get down into the electronics. It is still better to stop the water getting into the boat. Essentially the waterproofing we do is to save our gear should the boat get a lot of water in it. In normal use there shouldn't be any more than a small amount of water getting in, none is best, so mostly things only need to be water resistant. But...as we know water will find ways in at times, so it is just ensuring that the water can be tipped out and boating can continue because it didn't get into the electrical boards. Sealing the circuit boards as SweetAccord has suggested takes things a step further (better).

Agreed in the best cases yes, but if you crash or the boat flips or other possible things happen like the hatch comes off etc, more than a drip may/will get in, so you want to protect as much as you can cause you never know. Motors don't need protection, but all circuits do, reciever, ESC, servo's.

I hit something once with my mini hydro (think it was a turtle) and it was upside down for a while. The hatch tape eventually gave away from the water, and water flooded the hull. Nothing was damaged, and that's the idea. Sure you can make it water resistant, but waterproof is just better unless you know you will never have a bad run or more than a drop or two get inside the hull.

Hope that helps.

Never run fast boats where people are in the water, no radio is infalable and your fun is not worth their safety.

But it's a good quick way to give someone a haircut! LOL

Right ,with the shaft up it will be prone to drips leaking in around the shaft ,I had heard about installing an O ring ,but I'll try your way ,thanks

Another way is to pack the servo gear side and electronics (back side) with Marine Dielectric grease and add a silicone shock ring under the servo horn. When adding grease in the gear area, don't go crazy. Just pack in where water can enter in. This also keeps the gears lubed.

the best presented vid i have seen,( oh i know there are others) but it's good to see good guys without all the BS, swearing and nonsense and horrible music. these guys were hecka fun and did an excellent job. i didn't realize Corrosion HD was that much better. i've used the regular for many years and for the SpeedX for slot cars, fishing reels.

Yea I agree you need to make sure all is sealed up!! Worrying about the internal parts would be the second in row for preventing problems before running. Some of my boats have been upside down or the bow bobbing for a half hour or more. Telling me the upside down one was sealed good, and the sealing of electronics was good on the one that the hatch broke in half. Check your cooling lines for leakage too!

Get a Savox waterproof servo.

Old thread. Looking back.

Tons of torque but I've had a number of these waterproof Savox fail. Water inside. I think the Hitec with the blue cases might be better.

Anybody tried one of these?

I use Hitec MG servos both digital and analog.
Take the bottom cover off and fill it with Corrosion X
I have had many boats fill with water after a bad flip or a broken water line inside the boat.
I have never had a servo die on me yet.

the Crawlers are using them in there rigs i want one, just one to try. those guys go thru many servos. i have two crawlers, but i do not use them that much just over sized models for me.
just pinned over at RC Crawler about the P120t.
nice find.

has any one used an 'O" Ring below the Horn? i did once using a o ring from a buggy shock build kit that were leftovers, read some where and gave it a try this was way before i knew to use whats been posted here. did that application work? yes, how well? i don't know never got that buggy that wet to find out and i believe i'll put an o ring on one of the boats. i think after doing what has been mentioned here should suffice and how long these lil' daddy O's would hold up to the twisting motion. eventually squeeze and rip out old, rubber band cracked or?
somethn' else to lube and replace, kinda of the reason i never put them on any thing else.
