Servo started slipping, not sure why

[malex]

Hey All,

Today lost steering on my dbxl-e (stock servo) and not sure why or if fixable.

After removing the servo case I can see the gears look good and with it disconnected from the wheels (no resistance) the servo turns just fine, but with some resistance the lowest servo gears just spin.

It seems more like something is loose instead of broken, but not sure.

Here's a video showing what I mean:Video

Any advice would be much appreciated, thanks!

Thanks, I'll check these out!

But I'm traveling a for the week so getting new parts is a bit of a challenge. Brought the car for the trip so am hoping this one can be salvaged lol

Its toast mate, you need a new one. A decent savox or hitec is all that's needed

Where are you located/traveling?

I would assume that there is a set screw or a pin that is suppose to hold the gear tight to the shaft. I'm thinking the setscrew is lose or pin broke. I've never taken a servo apart so I'm guessing.

San Diego!

Lots of hobby shops, but not finding much carrying 1/5 scale parts.

That's kind of what I'm thinking. Guess since I'm going to replace it at this point I'll go ahead and tear the whole thing apart and probably break it more in the process but hopefully will learn something lol

Thanks! ?

Found the issue. With this stock servo, there are a few gears within gears. I thought they were one solid piece, but no. This is what came loose: https://photos.app.goo.gl/1W2DETdGM15m7VEW7

Seems like a flawed design to me.

Upgrading to a Spektrum servo now.

Cheers All!

Engineered failure.
