I have an extra 20kg - just hit me up if it doesn't make it. I posted early in the event thread - stop by the coach and say HI.

Installed one today in my primary rig and it works just great!

I did have to grind off some of back of the oversize servo horn so my track bar would clear. All good though, happy with it so far.

Running it on 7.4 for the time being. If I burn it out I have another.

The savox 231 works just great on 7.4 as well. Plenty snappy. I'm sure neither are like a 500oz one but good enough for what I do. My rigs are light.

You openly stated that you fed more voltage (4s lihv, or 17.4v) to electronics than they were advertised to handle... and they failed. The vendor stood behind their product anyway, I'm not seeing where your quoted statement is coming from, but I'm all ears? Just trying to keep things real here.

You are correct. I was naive. I thought my LiHV fully charged was 14V so I used it and burn. but one thing I noticed the JX Metal gears was a bit thinner than other? ( well I could be wrong )

Anyone running 1/4 servo on bigger builds, whats a good one for cheap.

I was told that even a cheap one has more torque than most other high torque 1/10 servos

Make sure you have room to run a noticeably larger servo with different mounting hole locations...

From Tower Hobbies, listed under 1/4 scale servo:

"This Servo is a Hitec Mega 1/4 Scale Servo"

Hitec HS-805BB

2.6"x 1.2"x 2.3" (66 x 30 x 58 mm)

Standard 1/10th scale servo:

1.6" x 0.79" x 1.6" (40 x 20 x 40mm)

That's a big difference in size - mounting points will differ greatly.

It's only 1/2" on the top & each side & 3/4" on the back. The JX version is 62kg (861oz!!) at 7.4v and only $36.

Tower Pro waterproof 30kg servos

I may have asked this before, but aren't aluminum gears generally stronger than brass? I ask that because Towerpro's other 30kg servo, the mg959 uses aluminum gears and the gears are already the weak link, going to brass gears seems like a step backwards? The 959 had absolutely nothing for waterproofing though, no o-rings, coatings, seals, etc.

The above picture looks a lot like the old mg995 to me, which was more like 10kg, and not waterproof.

I don't get it? On my E10 there's massive amounts of room for that, enough where I was considering 2x std servos at one time. On an scx10 you can fit it easily with a vertical longitudinal mount like this rc4wd kit allows. I don't have one in front of me but it looks like the body (not tabs) would still fit between the rails in a traverse mount. On my clod it would limit me to putting it ahead of the axle, but I could live with that if it had that much more power & larger gears.

I'd understand space concerns if people here were building bagged lowriders, but in general people here lift their trucks more often than not. 1/2" would be like 5" in real life, that's not insane considering how large our tires are. The stock Wraith tires would be 52" full scale.

It depends on the metal used. Cheap aluminum can be much weaker than good brass, while high grades of aluminum can be stronger than some types of steel. The metal quality maters more than the type in this case.

Understood. Nowhere in my post did I say it was not possible to do this. I was simply pointing out the size difference, which in some applications would be certainly less than satisfactory - I (for example) would be quite unhappy with the appearance of an on-axle-mounted servo that much larger. They already are one of the least scale appearing items on a AR60 equipped RC.

Used these two gears out of this servo, slipped right in. The ratio goes up a bit so will be a little faster with a little less torque but easier than trying to source a new gearset!

I like your style Shawn. I keep all my dead servos hoping that one day, one of them can lend itself to the repair of another.

I'm not gonna lie, my first run on the "46kg" jx was a little disappointing. Running 6v it is supposed to put out 37.5kg, but it is definitely weaker than the "30kg" mg959 that it replaced. I ran out of daylight today, but I'll see how it does on 7.4v tomorrow.

Thanks. Unfortunately this is out of a new servo that is destined to become a winch. Fortunately, the 360° 5521 only costs around $12 shipped. The gears alone would probably be double that shipped if you could even find them.

A china imported (aliexpress) DS3215 servo installed this weekend...like it a lot. Very snappy and works just fine with the HW1080 built in BEC.

Plastic middle gear, why, no thanks.

Good catch. Plastic gears are inexcusable at that price!

Then what do you call a plastic gear in $180 Hitec servos?
