Affordable, tough and fast
This little servo is working great. It is very tough and easily move the front wheels without issue even when the weight of my heavy Bronco or Defender are resting against the front wheels. Responsiveness is top notch and very quick. Faster than stock my quite a bit and about as fast as any I have used. Will buy again for other builds.

Great upgrade at a good price.
Servo looks great, black with aluminum cuts. Fit perfectly with the Injora aluminum axles. Much better performance than stock servo in speed, power, and durability, and price. This set comes with the servo, mount, and servo arm, for the price of the OEM servo alone. Semi easy to install (there are no instructions) If you are using the Injora aluminum axels you will need the 2 micro grub screws and a .05 allen key to install, but set servo into the mount first then tighten the grub screws, but not too tight. Not sure how it fit stock plastic axels.

Love it (Make sure you center your servos for your setup)
Love it. Mine came pre-centered ,I knew after I powered it up it was gonna be great . Its adds great weight to the front and is much quieter than the stock(my stock one destroyed its plastic gears). It installs just like the stock as well. Amazing price👍

Nearly SILENT, and POWERFULL!
Works amazingly!!! Super easy plug and play replacement for the steering servo. You may need to adjust end points but the Quality of the servo speaks for itself. I had to take a Dremel to the servo mount to allow room for the horn's screw (nothing bad less than a MM). this shouldn't be an issue for others as I am going for a very lifted truck. This means the servo needs to be leaning towards the front bumper as much as possible, this limits the space between the attached servo horn screw and servo mount.

Awesome servo
Super strong and faster than stock. Easy to replace and adds a good weight on the axle with a laydown axle. Looks awesome and is a good price for what you get

Rien a voir avec l'original la qualité est tout simplement incroyable. D'une souplesse et surtout plus réactif. Mais a ce prix même pas une petite dose de frein filet pour bloquer juste les deux petites vis qui bloque le support sur l'essieu. Je trouve ça dommage vu le prix. Car si vous mettez pas de frein filet rien empêche les deux petites vis de partir sinon faut les serrer sur le servo et la franchement je conseille pas d'une vous allez le marquer voir écrasé le boîtier qui est en aluminium là vis et en acier elle. Aluminium vs acier c'est l'acier qui va gagner. Perso je vais raccourcir deux vis que j'ai pour les remplacer. Je comprends pas que injora n'est pas pensé à ça .

Been using this servo in my antweight combat robot's flipper arm for a whole year as it was the most powerful micro-servo I could find. It's done 50+ fights without missing a beat. This servo has been put through hell and expected it to last only 20 or so fights before needing to be replaced. Has been: - Stalled for long durations - Taken direct hits from spinner weapons (only 1mm of abs between the spinner and the servo casing) - Force driven from huge hits on the arm it's controlling (internal gearbox still fine) - Run blistering hot for 10 or so minutes Measured 11 kg-cm when it was new, and still measures about that amount of force after all of this. Using it on 3 other bots as well and not a single issue. If you are using it for a crawler, you will probably not have an issue!

Fits perfect with aftermarket shock towers. reroute wires for more clearance. Does not hit top. Turns super tight. Very quiet and powerful. Might need to upgrade T-bone and Adjust steering points. Because it turns crazy tight! I highly recommend. Most upgrades like this are not waterproof. Traxxas is but rubbish!
