strong
This INJORA 550 brushed waterproof motor has been great. It was easy to install on my 1:10 crawler and fit perfectly with no issues. The waterproofing gives confidence for trail runs in wet or muddy conditions, and the 21T provides smooth, reliable power for crawling and general driving. Performance feels solid and consistent, and overall it’s a quality motor for the price.

Manufacturing error, but good motor
Fit same as any 550 motor. Operates as it should. Ordered 21T and game me the pep I wanted in my crawler. However I noticed some torque issues. Upon further inspection I noticed the brushes are in the wrong orientation and not making proper contact with the stator. They will wear in to a proper shape over time so I'm not gonna bother with a return. The "heat spreader" sleeve is merely cosmetic and comes right off.

Took a chance and WON.
Works perfect for my rig. Has the speed I want and the low end to slowly approach the stuff I'll be running over. Quiet. Ran multiple batteries and my motor didn't get hot to the touch. Just got warm.

Powerful and smooth
So far I've ordered two of these motors, in the 21t configuration, for two Chinese vehicles that formerly came with the cheapo 540 "silver can" motors. Both have been a perfect replacement combining torque and reliability. I may be seeking out a 12t if I ever find an old Traxxas chassis to mess with👀 Overall a great RC product at an affordable price point. Will be frequenting Injora for all my brushed RC motor needs.

Perfect fit.
For the price I can't complain. It is a bit more noisy than the original but works better.

Très bonne qualité
J'ai monté ce moteur le 21t sur un petit bateau de 60 cm ,couplé avec le variateur 320a et une batterie Lipo 2s, c'est équivalent a du brushless, j'ai était surpris du couple et puissance du moteur, très bonne qualité.
