GoolRC Upgrade Waterproof 3650 3900KV Brushless Motor with 60A ESC Combo Set for 1/10 RC Car Truck

You must spend some time configuring the right way. Here's some advice. 1) I used a FS-GT3C controller/receiver to connect to the ESC. This made it much easier to fine tune. 2) Mine went WAY faster in reverse! Despite buying the motor/esc combo and matching the red, blue, yellow wires. My car was twice as fast in reverse. To fix, I swapped the blue and yellow motor wires and instantly my RC car is insanely fast going forward. 3) The ESC can be programmed via an extra programming card. That will help you set the min/max strength of forward, reverse, braking strength and more, including some settings you may not be thinking of. 4) If you are coming from a brushed motor to this brushless motor/esc, be sure to give it a gentle break-in. I used more than half a battery before I really started pushing it to max speed. 5) I built a Tamiya Hot Shot 2 and a Tamiya Dark Impact and managed to cram 2 of these motors in. While I was successful at fitting the motor in both cars, the Dark Impact required that I grind down the tip of the motors drive rod. They give you a generous size on the motor, but the Dark Impact has space limitations. I own 5, 1/10th scale RC cars/trucks. 2 are brushed, 3 are brushless. Bang for the buck, excellent price, faster top speed than expected. Cons: The esc is just a little big. Not by much. But, let's just say I really worked to fit it into the Hot Shot 2. Was an easy fit on the Dark Impact. Fitting the motor on the Dark Impact took some thought. It'll only fit 1 way! 3s Lipo promoted on listing, paperwork in box says 2s only. I only run 2s, but I've noticed others say 3s works. While the numbers say it is possible. I believe the manufacturer is trying to keep us within safe limits. Best to stick with 2s and if attempting 3s, monitor very closely for heat build up. Pros: No motor heat buildup on the 2 I am currently running. Motors seems to stay way cooler than brushed motors. Love the torque and top speed (keeping stock gearing). 4wd cars seem to love it. A really nice upgrade for anyone coming from brushed to brushless. There's more room for tweaking. I like how many adjustments I can make. I also really liked the price. I'm actively racing my two cars, and if I run into troubles, I will be sure to update my review.

I bought this brushless kit to upgrade an old Traxxas Stampede with previous brushed motor. First of all the listing never states you need a programmer to program this. I installed this kit and had terrible cogging. Ordered the programmer and set all the values accordingly and the thing ran great for a couple of batteries. Go get it out this morning and truck won't move, no beeping sounds to confirm motor communication, red light on esc is working. Pretty quick, esc smoked. I have owned this less than one week and nothing but trouble. Going back with factory Traxxas parts. I do not recommend.

This motor is so fast . Imma nub, may have to get a smaller motor cuz I stay braking stuff

Beware use of this the one I got was super fast but when installed in a 1:10 scale rc truck it has a hard time getting started

Works fine. Big though. Ended up taking off the fan.

Got this as a replacement for my stock esc and motor. Saw great things about it on YouTube. But this motor cogs so bad it hardly gets the car moving. Even after I programmed it the system was still hardly moving the car. Also the motor gets really hot really fast. Way hotter than the stock motor. Only running a 2S 20c lipo in it too. Don’t buy this. Spend the money and get something good like castle or spectrum cuz this is just disgraceful. Also went to their website for customer service. The only thing that came up was just the words “customer service” and when I clicked “contact us” it said “coming soon”. Don’t buy this.

works, but setup is hard ...

Running this esc and motor combo with a 3s lipo so far the first 15 mins have been promising, will update!

So far this combo does not work in a hotshot II. The car can't run from stop. It would start running off the ground but not on the ground. I set power to half on the remote, if I use more it will die mid power. Not happy with the product ...
