All the servos that come waterproof from the factory are weak. Buy a decent servo and conformal coat the board and fill the case with dielectric grease.

Cheap servo: solar 772

Good servo: hitec 7955

Great servo: hitec 7950

+1 on the Solar D772. Just waterproof it yourself...it's easy.

This is what I use to waterproof all my electronics: MG Chemicals 419B-55ML Conformal Coating Acrylic lacquer - Liquid - Amazon.com

That stuff looks good...just placed an order. Thanks for the link! How long have you been using this stuff?

Since around spring time. I use it on everything now. Servo boards, sensor boards, receivers, and speed controls. I have even been thinking about doing my 4pl since I use it when it's snowing out.

Savox waterproof .. not weak

That's a matter of opinion.

X2 on the D772
Best MG/HT servo on a budget. JMO

I used NeverWet on the D772's circuit board...
then coated the majority of the servo's external case
with spray on plastic dip.

Then I packed some extra grease inside the upper case
in and round the output gear/bearing.

After the interior circuit boards and external plastic dip coatings...
put a shock O-ring over the servo's output shaft (exterior).
with that seated in some grease to help with the seal.
The servo horn sandwiches the O-ring between the case
and itself. The added grease creates a decent seal there.

^ I use a clamping style/type servo horn.
This allows a tight tolerance... but does create drag/friction.

So far no issue when splashing about...
Tho' I must admit I have not submerged these components
fully as of yet.

If the servo leaks and/or fries... was only $17.00

I used the NeverWet on all my other electronic circuit boards as well.
...ESC, BEC and RX

* For the BEC...
removed the shrink wrap first...
coated the circuit board with the NeverWet 2 step process...
then re-shrunk some tubing on that to protect it from abrasion.
I also sealed up the ends with plastic dip.

Then all but the ESC fits into a sealed electronics box (added measure).

If the ESC fries... would give me reason to purchase the SW3

Just for the record, so the op can make an informed decision, never wet is not made for electronics. The conformal coating I linked above is made for electronics.

True (tho' I'll bet it's primarily due to the liabilities)

A quick look at YouTube shows it working while submerged.

applied incorrectly... it could be a fail.

But that could be said for any product.

I use the Solar D771 on my SCX10. D772 was too slow for my liking. I do use a bec too to bump the voltage to 7.2 just under what the servo is rated for.

The best waterproof servo and just a waterproof servo that will fit your needs can be two different things...DO you run big 2.2 tires?..Is your rig heavy with modded steel and aluminum parts?
Do you use high steer knuckles?...In all honesty a stock servo is plenty of power to turn your truck without any special needs for a super strong servo.

If you want a waterproof a few companies make them in different price ranges...The most common servo used is a Traxxas 2075..Its not a power house of a servo and it doesn't have metal gears
but its a well proven waterproof design that has satisfied many for its intended purpose.

As some have already said its not difficult to waterproof basicly any servo...you can take any 35-40 dollar servo that's even better than stock and make it work for you in water.

The savox 0251 is the strongest servo I know of in that price range and its more than you need.
Hitec HS645MG is a very popular servo and has been around before anyone ever heard of savox servos...Its not as strong but its plenty strong and reliable.

Obviously the BEST waterproof servo will be the most expensive one you can find in many eyes...All though overkill seems to be a growing trend in the rc world.

When it comes to the actual power of a servo you get usually 2 ratings...one at 4 volts and one at 6 volts.

If you buy a servo that says its 200oz of torque at 6 volts but your esc is only providing 5 volts to your esc its not going to be as strong as it advertised rating for 6 volts.

So keep that in mind.

A lot of servos now have three ratings...4.8v, 6v, and 7.4v.

I haven't seen the 7.4 ratings myself...I have so many hitec servos from years and years ago I only remembered seeing upto 6 volt..,never really shopped for anything servo wise lately..lol

Thanks for the info though.

[boohoo]

the best wp servo i`ve seen is a savox my mate runs the 20kg (i think it is version) in his wraith and scx10 with no probs. i run the hitec and its complete pants compared to the savox and its way cheaper aswell than the hitec

Yeah man there are a LOT that run on 7.4v...even the $17 Solar D772

When I run out of hitec servos ill look into it...lol
Thanks again.

The savox waterproof with 277 oz isn't bad but doing some waterproofing on a higher torque servo may fit your needs better if you want more power.


I've been running a d772 on 8 volts for months. Plenty strong and it is much faster than it was at 7.4 go figure.

Well i have to say its nice to see such a low dollar item perform as good as some name brand over priced stuff..The type of stuff i like now a days

Youd be surprised at how much some low dollar items are sufficient enough as upgrades...Too bad more don't see it that way in some situations.
