Durable, strong and fast. The 11kg servo is one of the best upgrades for your rides. It's as simple as plug n play

After burning through multiple cheaper plastic servos, I opted to buy this one. It's very powerful and responsive, I wish I had bought it sooner. This one is not technically waterproof but I don't submerge it ever. I've had this thing in some very tight spots and it pushes through.

Have had zero issues with this servo after multiple battery packs! I upgraded to brass portal axles and stripped out the stock servo almost immediately so I went with this as a replacement and did not regret it! It has enough power to be able to walk the front around while crawling over obstacles too!

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.

Not sure you can beat this servo for $40. There are stronger servos out there (nsdrc,mofo) but at this price range it's a solid servo. Good torque and speed. This is my 3rd one.

Works well with larger tires and weighted wheels. The servo isn’t designed for the TRX4m necessarily because1 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.

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

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 .

Aunque Amazon oculta características, la tienda de Injora te cuenta todo, incluso que no es sumergible, así que 10 para Injora y 5 para Amazon que me lo trajo

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!

Wer sein Fahrzeug aufrüstet muß wissen,das es schwerer wird. Orginalservo von Traxxas war dafür nicht ausgelegtund ist kaputt gegangen. Jetzt läuft alles stabil.

Servo straordinario, fare solo attenzione se andate in acqua perché non é waterproof
