Big Rock Big rock Servo issue

[RCbuzz]

I've been replacing all of our 3S servos with the 6S S652's. Affordable and direct fit.

I do this too! They work nice on the 3S cars.

I found a matching metal servo saver arm it worked beautifully for 1 minute then started making noises, overheating and now dead.. Time for an upgrade! love a good reason to go to the hobby shop

Not sure if you meant you removed the servo saver for a solid metal arm. If so, I highly reccomend you have a servo saver of some kind. It really does save other component when/if you steering binds on something.

Good luck!

After watching a video years ago on a utuber testing many different servos. And every one was over rated in tourqe numbers. That 25kg is actually like 19kg. Some servos were closer to what was printed and some ate worse on the servo case and in description.

Same here, couple years ago I watched those too b4 deciding on a aftermarket servo. Pretty cool little machine they made. I've used DS35 & DS25 servos in some rigs. Running Power HD in my 6s rigs.

Nice you saw that!!

put in a new 45kg and HR Bell crank. Now what the hell lol so frustrating

Dang that stinks! Not sure bro. Unless something is bound up.

 

[Jsvt289]

It seems like there’s a little more play in the knuckle/arm on that one side, but when I disconnect the servo arm, everything turns smooth with my hands

 

[332_RC]

So the servo doesn't move much when disconnected from the arm/link? Or will it full sweep then?

 

[Jsvt289]

Servo whips fine with strength when disconnected

Is the HR rack binding at all?

What happens when you move the steering from the servo arm. Smooth or something to tight?

 

[Jsvt289]

No binding when I disconnect the servo arm, but one thing I just thought of is that when I centered the servo and put the arm on it the arm doesn’t point directly dead center. It’s either a little to the left or little to the right.

You put the aluminum solid arm on or the Kimbrough

For now, just the metal servo arm. Last night everyone was saying that my issue was a servo saver so I put on a metal servo arm to count that out.

 

[332_RC]

Huh. Only thing I can think of is the BEC is on 6v. I can't say it's the receiver, not sure. Is the servo plug backwards? Idk

 

[Just a hobby]

The worn parts could be a problem. They are cheap enough.

 

[Jsvt289]

Esc is set on 7.4v. But it could be the receiver.. I did change out the receiver unit that you plug everything into bc I broke the antenna wire by accident hmmmm

 

[332_RC]

Which receiver did you swap to

 

[Jsvt289]

Receiver is stock spectrum slt3 but put in a S615 to bind to it

Arite fam just had some successful testing. Put a different servo arm that lined up perfect when centering, found a metal pivot ball was stuck causing almost no play, reset endpoints and fixed the camber/toe kick. We’ll see how it does after going 10 ft in the air tomorrow. Full trigger bashing!!

Well its about time, I was going to call a specialist

Cool. I chased a ghost in my K6 bulkhead-noise- finally just swapped the entire bulkhead. Musta been a warped bulkhead.
Glad you found that. Send it
