Waterproof single servo???

[jodart]

Any recomendations?

[Jimmie Neutron]

I don't know of any waterproof ones... my BlueBird 35A has o-rings at every seam, but is not labeled as waterproof.

It is extremely easy to waterproof a servo... only took me maybe all of 5 minutes to waterproof my other servo.
I disassemble the servo, put a glob of grease at the servo horn, smear some RTV at the seams and reassemble.

As Jimmie said regards waterproofing.

I have my second one of these on its way:

i'm looking for one as well

Like Jimmies's bluebird, my futaba S9157 has O rings around the seams, under the screw heads that hold it together, and one around the output shaft. Also like the bluebird it is labeled "water resistant" on futabas site...not water proof.

I installed a Bluebird without sealing the seams as I never intended to run in water. On the first trip out with the new servo i did a back-flip off a ledge into a creek. I pulled it out immediatly but was too late. it shorted within five minutes. I opened it up when I got home and it had a lot of water in it. I dried it but it was toast. My own fault...I was happy with the power of the servo in the short time that I used it.

I might just get a savox and wp it myself

[Jimmie Neutron]

The BlueBird 630 is too weak to go with just one servo at 195in-oz... stock is 125 each with 250 total torque.

[DayWalker]

Would the 660 be ok? Torque At 6.0V: 14.2kg/cm , 190 oz/in still under the 250 total of stock setup I see.

or theres

L530DMG Torque At 6.0V: 24.3kg/cm , 348 oz/in
860DMAX+HS Torque At 6.0V: 23.2kg/cm , 322 oz/in

Any of those will work.
I suggest a target torque of 300-350... anything over 350 is going to overpower the stock servo saver.
(Not saying don't go over, but I wouldn't pay extra for it)

[oldjeeper]

The Bluebird 35A had good power. I will waterproof the next one even though I don't plan on getting it wet.

[DayWalker]

But the Savox SC-1258TG doesn't have that much torque does it? and i've seen a few people use those.

[DayWalker]

35A looks tough I assume you run a bec for that? I didn't really want to run a bec as didn't want to chop wires as my summit is still under warranty

[oldjeeper]

I did not run a bec. Just plugged it in. I had to reverse the servo after installation which is easy.

The 1256tg is stronger. I use it on all my trucks and buggy an truggy

Like Jimmy said..."stay within 300-350 oz torque" and it will be much better than stock. I run mudslingers that have 18oz of weight added to each front wheel. I just like climbing in the rocks. The stock servos just could not handle the load when faced with extreme conditions. The 35a, hd servo saver spring, all with stock linkage worked very well.

Do you use single or dual 1256gt in the summit?

Here is a few sites that should help you:

will you guys please share with me how you adjust your HD servo saver when installing? is everyone doing the washer mod? My Savox 1230 gets here today! Pretty excited!!

[Finisher]

I used single, however I ran an aftermarket servo saver setup. I also ran my steering servo from a life pack

I did not use the washer, just the HD spring and there's really no adjustment. Just tighten it down. I would recommend using locktite on the screws to keep them from backing out.

[jamann]

I used the hi end "silver coloured"washer In mine.
The bling factor alone...j/k lol
You may need to try a couple different ones.i found one that fit pretty close.
It is just acting as a spacer so to speak

nice maybe I can get some one to custom make me an aluminum or titanium washer

[DayWalker]

anyone got a link to a washer that would be suitable as I don't have the kit to grind one down etc.

[oldjeeper]

Take your servo saver spring to your local hardware store and try and match a common flat washer with the diameter of the big end of the spring. slightly smaller will be okay just make sure it doesn't go up in the spring. Get a cadium plated or other coating so it doesn't rust.

thanks. so why use the washer? I've seen a lot of people talking about them but I haven't come across why yet. Does it make the spring stiffer?

[oldjeeper]

Yes, it just takes up space in the spring seat causing it to be tighter.

[oldjeeper]

I elected not to use a washer. I think it might lessen your chance of breaking something in case of a hard impact. With the stronger servo, it eliminated my lack of steering power. That's just my opinion...the are many who do use a washer with no problems. It is your call...

[jamann]

I was running big tires rock crushers
Hi torque servo was flexing the spring too easy.it will still give on bigger hits but will turn even under some load.
Try it without first and see, may not need it.

ahhhh! it's here!!!

[jamann]

Also the heavy duty spring is already installed,but a back up part is never a bad thing.

you mean it's like that stock with the heavy spring?

[jamann]

Yes sir, it is.That was my first thought back when I went single servo.stiffer spring?
For me (How i use my truck)it seemed logical to make the saver stiffer.I just dbl'd the stock power.i wanted the wheels to turn when I needed them to
Why I went to hi torque in the first place.
I do want some saver action still, though
Just takes a little more to activate it.

I just kind of find it hard to believe that no one has an advertised 300-350 oz waterproof servo out there. I mean, with as big as the whole crawler thing is and all. I still plan on fordging streams etc, so waterproof is a must.

[Jimmie Neutron]

Probably because it is so easy to waterproof it yourself.

[happymachinist]

Advertising a servo as waterproof could be a warranty nightmare for the manf...a flawed o ring or seal and their replacing a $75+ servo due to water damage because somebody thinks their truck is a submarine.

Like said a little handy work and you can make nearly any servo you want waterproof.
