Buy a new $3 gear or a new $50 servo, your choice.

I would bet that 90% of the 'metal gear servos' have a plastic 1st gear to prevent the servo from blowing up completely.

There always has to be a weak point. If not for that $3 gear, it's the case/servo pins. Make those stronger and you blow the nose off the servo, etc.

$50 just plain can't get you a premium servo
$90 will get you there, Futaba IMO is the best, have an S9551 that's older than any car I have ever put it in lol

The hitec 5925 was $90 and I never would of bought either one if they told the truth! I have high$ servos in my cars but figured I'd save on my daughters as she didn't need as much speed. They were both listed as "durable" "metal gear" and simply were neither! Upon doing more research a lot of the modern servos at or over $50 are indeed "FULL METAL GEAR" But who knows until you open it up???

EXACTLY!! "Metal gear servo" doesn't mean indestructible. The main gears that absorb and deliver all the torque, abuse, and wear are likely (and should be) metal. There has to a fail point somewhere like whitzac said. IF you're stressing a modern metal gear servo to the point of failure, you're likely exceeding it's advertised ratings. You honestly need to be using a "tougher" servo.

Modern electronics are insanely durable. But not bullet proof.

I'll stop there before I go off on a tangent about....well let's just leave it at that.

So as I mentioned 1 plastic gear.

The point is that when that plastic gear is stripped there is something wrong with the car.... no or a too tight servo saver?

Most, if not all, metal gear servos have a plastic gear to protect the motor. Easier to replace gears than the motor. Unfortunately, most don't sell just the plastic gear but the whole gear set. Unless you can find the compatible gear set in plastic. Cheaper servos have their place and expensive servos are not indestructible. Driver needs to know the limitations and/or build in protection.

This guy gets gets it.

You want a planned place of failure, why do you think they put lines in concrete.

Replacement plastic gear for your spectrum

I couldnt find one for your Hitec in the 5 seconds I looked.

The 2 modern 1/10th buggys they were in B6 and B64 neither use a servo saver.

And I wish the gearsets were only $3. Or were in stock for that matter.

Instead of dropping $100-200 more on servos at the track instead of packing up and telling my daughter we can't finish the race day!

Also both these servos are listed as being rated for 1/8th scale use so I doubt a blinky 17.5 geared slowed for her pushed them beyond their rating!

Then there is your real problem, not using a saver can do a lot of harm to a servo.

all my 1/10 scale buggies accommodate a servo saver easy..team C losi A&E and a few others.i even have a few on my 1/16 .1/18 scale and 1/12 scales.

I would not trust anything by spektrum. Why not buy sanwa or futuba those are the Big servo companies

I linked you to a 4$ replacement 2 pack of plastic gears. you can buy 40 packs of them for 200 bucks and never worry again.

This was with 30 secs of searching online. I get your upset and want to vent but work with us here.

Yeah, the "metal gear servo" in my AE SC10RS RTR broke within two hours of driving back in the day, because it had plastic gear in it. This happened despite the overly soft servo saver. Of course the replacement gears were only available as a full set. Ridiculous. What's the point of protecting the servo motor if you have to replace the plastic gear every few battery packs? How the hell are you supposed to finish races with something like that? With one plastic gear it could just as well be all plastic gears, because the thing is only as strong as its weakest link.

These days I can get a perfectly working, ACTUALLY metal gear servo from JX or Turnigy for nearly the same price as the replacement gears for that crappy RTR servo. Back then I didn't know about the budget stuff yet so I just got an expensive Savox for it and disabled the servo saver. Zero servo problems with any other servos even without servo savers.

Had I known better beforehand about how bad the original servo was and so forth as well as about reliable budget electronics (I got oversold on my first car purchase, the B5M, and had an inflated impression of what electronics cost), I would've just bought the SC10.2FT instead. Though I'll say the 3300kv stock motor and SC700 ESC have been quite decent and reliable, especially for indoors where the slower top speed isn't a problem. The radio wasn't bad either, though I sold it with a different car. The servo really was the weak link of the car.

I would argue that the solid aluminum case brushless servos from JX for $45 shipped are indeed comparable in performance with high end servos on the market:

I've been racing these JX servos in both my 1/8 buggy and truggy for the past 14+ months and overall I have been pleased with their performance, a recent race day proved the servo was quite capable with a 98.7% consistency (my personal best) for someone recently bumping up into Expert from Sportsman:
Thornhill Racing Circuit :: Thornhill Championship Series #1 :: Expert Electric Buggy (Heat 1/1) :: LiveRC

I do need to point out that my truggy servo did strip after the first 10 months of racing and the replacement gear has held up fine for the past 4 months of racing. I've also started to notice a pinch of slop starting to form on the buggy servo after 14 months... still having great results even with the slop, but planning to replace the gears as a preventative soon.

Although JX doesn't sell gear replacement sets (most name brands charge $25+ for a set) I've found that I can get get a donor servo for under $10 and simply swap out the metal gears from the cheap servo making this a win-win for me ;)

They put those line in there for expansion and contraction from season to season so they DONT fail......
