INJORA 11KG Coreless High Torque Servo with Mount and Horn for TRX4M, Black

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.

This fits Perfectly on the trx4m stock and injora steering arm.It's powerful, speedy and well built!

Best servo I think I have tried yet I wanted to mention in the description is mentions that you can't use a stock trx4m servo mount and I was bumed at first since I previously upgraded to the injora brass servo mount but I figured out you totally can. The reason it dosent work is the center hole on the servo is a thinner screw and the brass one has a bigger diameter screw. So I took out my dremel with a sand paper bit and sanded out the center hole on the servo on both sides just enough to get the orginal servo mount screws in and it worked perfectly. This servo is definitely 2x stronger then the traxxas trx4m 2065r servo upgrade. I was having issues with my full metal/brass rig with the 2065r not having enough torque in the rocks and would dead stop sometimes making a line more difficult. Only downside I see is no waterproofing but what I have seen on the rcfunandgames youtube channel you can take this servo is water crossings if you don't dunk it too long. At this point kinda given up on the whole full water proof thing since my injora reciver isn't waterproof aswell. Dosent make sence injora make the mb100 esc and injora motors waterproof but not the reciver. But either way for a rock crawler build this is a must have. I do wish injora would come out with a 4mm/8mm total brass steering arm and for the laydown servo kit a brass arm aswell but I can't complain because injora is killing it with the upgrades

Super easy install, fast turning, lots of turning strength

Works great! Easy install!

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

Used on trx4m highcountry and had no issue

Much much better than the 7kg version esp if you have 1.3” beadlock brass wheels and large tyres

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 minutesMeasured 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!
