GoolRCSurpass Hobby Waterproof F540 4370KV RC Car Brushless Motor with Brushless 45A ESC for 1/10 Scale RC Car Truck Indispensable Accessory for Modification Enthusiasts

I ordered two of these combos to update two old traxxas rustler trucks I bought in 1998. Put them with a 3s 5200 LiPo pack and a 19/86 gear combo. These things are ridiculous. Nearly uncontrollable power and speed. Crazy torque off the line and can’t get to top speed without the front end wanting to lift off. Only made one ten minute run with it due to time constraints but it didn’t heat up at all. Wheelie machines now. The ESC paired easily with the new radio/receiver combo. This was my first foray into a brushless setup and they really should clearly identify which wires on the motor plug into which wires on the ESC. The wires on the motor are color coded, but the wires from the ESC are all black so that is no help. On the First attempt, the motor was running in reverse. I switched two wires and got it to go forward, but it was then getting full power in reverse and half power in forward. I put the wires back to the original configuration and then used the radio to reverse the direction and got full power in forward. Would be nice if the instructions clearly marked which wires go where to prevent this kind of issue.

This motor/esc setup worked great in my 1/10th scale on road rc

If you are looking for something the size of a 550 or a 540 motor this ia it and especially if you are looking for something that works with the wltoys a979-b this is it!

My first set had a defective ESC-I drove it for 10 minutes, let it cool for a few hours, and plugged the battery back in, after which I was greeted by the smell of melting plastic and electronics smoldering, accompanied shortly after with thick black smoke being released from the base of the ESC. Very disappointing, especially for my son who was really looking forward to driving it.However, after getting a replacement through the warranty, I got a good set and can say this thing is crazy powerful. It may actually be over-powered for my 1/10 scale 4WD buggy. Doesn’t get too hot, isn’t too loud apart from the cooling fan-it is pretty loud-but I’d rather have a loud fan than have a second burnt-out ESC.Highly recommended if you can handle the power!

So far so good had a lot of bad luck with different brands I'm please with this one so far

ESC turns on fan and sends voltage to receiver.But that’s all it does. Will not send power to motor.Not sure if motor is dead or ESC is garbage, or both. Motor resistance between poles was within specs, so suspect ESC is no good.

Awesome purchase and great upgrade for my old Kyosho Buggy. Pretty quick for the price . Very happy with the purchase.

Fan went sooner than expected on esc motor has great power though
