INJORA Coreless High Torque Micro Servo with Mount and Servo Horn for TRX4M TRX4MT 1/18 RC Crawler Upgrade Parts(Black)

Solid upgrade part. Installed easily and improved performance as expected.

Strong and fast! At an ok price as well. Comparable to the reefs 99 but at a better price. So far unbreakable. (I have done all the things that have broken others) It is slightly longer than stock, but the wires come out of the side, so it can work to replace the stock servo (on trx4m) . I would take a star off because amazon had delivery problems, but I dont want that to reflect on Injora. Nothing but good products from them.

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. 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👍

Fits perfectly on the TRX4M

Haven’t gotten it powered up yet but out of the package it is extremely high quality aluminum cased servo can’t wait to put some power to it

Lots of power. Very responsive. Looks great too.

Works well with larger tires and weighted wheels. The servo isn’t designed for the TRX4m necessarily because 1 it’s a little tall. 2 the wiring comes out the front when it should come out the rear. The wiring blocks the screw and caused a cross threaded screw since the wiring is completely in the way. A ball hex will be required to access easily. It’s had an issue with the servo horn screw to the steering link keeps backing out even with threadlock and the thread isn’t stripped. If you work the steering back and forth it will loosen but if you tighten all the way it seems to bind the steering up so something seems to be designed wrong. I didn’t have this issue on my old stock servo even when I had aftermarket brass steering link on that one.

looks and work perfect

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 .

Everything perfect

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!
