great motor
this motor looks great and functions well for my use case. it's got great torque and i recommend it over the injora purple viper if you have a heavy rig. it's nice on 2s and even better on 3s giving you super slow crawl and a really good high end for those that like a bit of both when outdoors. the install was straightforward and easy but keep in mind it's a bit big and i had an issue with fitment but it was solved by flipping the base plate around. it pairs well with the mbl32 or mbl32 G2 escs. also it does get a bit loud on 3s making a weird screech at 75% throttle but i personally don't mind

Amazing motor.
Amazing motor and mount for the price. Has great slow crawl, wonderful torque, and excellent wheel speed. It works with every ESC I have tried it with and it is super quiet. It is a bit bulky so keep that in mind when planning your build and how it will fit in your chassis and body.

Don’t listen to the haters!
I’ve seen and heard too many people bash on this great system. I love it!! It is one of the smoothest, most linear and powerful motors I’ve used and I’ve used a lot. Additionally, it looks super cool when it spins and you know that the power to the wheels is there. Great motor, highly recommend this bad boy. I will be using it again on my next TRX4m build!

Awesome brushless motor for SCX24 platform
I purchased this injora fat viper brushless motor for My SCX24 LCG carbon fiber micro rock crawler build. This is a fat motor and it was tough to fit in such a small frame but I made it work nicely. This is a high quality brushless motor for SCX24 platform at a very reasonable price compared to other top brand brushless motors for SCX24. Runs very smooth and great slow motion for rock crawling paired with injora's MBL32 ESC. Very happy with this motor. I will use this motor again for future builds. Thanks injora for a awesome motor. Will update with photo.

Maybe the best micro crawler brushless option
Ultra smooth and powerful. Really nice purple anodizing and machining. Silent operation. Easy to install and perfect fit.

Everything is good except came missing pinion and spur gear.
Second one of theses I’ve purchased. first one everything is awesome Easy to install and buttery smooth That’s why I decided to buy another. But the second one came missing pinion and ring gear…

Pleasantly surprised!
I'm gonna start off by saying: What a deal. For a great motor AND a mount? No having to fight to get things to work when they shouldn't, cause this is just perfect. The motor is great. Cheap and very easy to install. Practically plug and play! The noise level to a stock motor is night and day. But comparing this motor to other brushless motors, it isn't the most quiet. There is a bit of noise in the middle of the powerband that I can't quite explain. Kind of sounds like beeping? The motor fits perfectly in the chassis I have (injora rock buggy) and with the included transmission mount, installation was a breeze. I bought this with a new transmission, so I put this motor on the new transmission to just drop the old one and throw this one in. Couldn't be easier. I can see the motor size being an issue in some other builds - so for those cases, I would recommend the smaller 1721 size purple/gold viper motor.

Amazing deal
Works amazing. Great low speed control, quiet, super easy to set up. Looks sick too. Low profile so it fits super easy. Literally plug and play. The local hobby store guy told me these weren’t the most reliable, but it was a quarter of the price of the less good one he was trying to sell me.

Men scx24 is nu een echte crawler
Deze gemonteerd in mijn scx24. Ging heel vlotjes, je moet wel nog een esc voorzien. Mijn kleine crawler rijdt nu als een echt crawler. Voelde eerst meer aan als een speelgoed

Amazing , don’t hesitate and buy now, you won’t be disappointed
What a great brushless motor, super quiet and very powerful. Would highly recommend . I used the Hobbywing mini 24 esc. All I can say is WOW,

Tanta modulabilità
Molto fluido e controllabile con il suo esc… non ho toccato nessuna impostazione software quindi sicuramente puó anche migliorare… occhio che è un bel bombardino serve un bel pó di spazio libero. Ho fatto anche 27 minuti con una lipo da 300 mAh e servo Emax analogico.
