FOC (Field-oriented Control) for Super Linearity & High Torque & Extreme Silence
New sensor technology has changed the feel, performance, and overall tune-ability of the new Axe ESC and Motor in ways some have never experienced. Field-oriented Control is the name of this new tech, and is something all new to the scale trail, rock racing, and RC world in-general. This new style of sensor allows extremely accurate control and sensing of the motor while maintaining extreme performance and reliability. The motor and ESC are able to match the RPM of the motor to your throttle position under all driving conditions. This greatly improves down hill driving giving this system the ability to drive down hill under complete control. FOC technology also makes the whole system extremely silent, the motor doesn't create the annoying PWM noise when it is running.
Intelligent Torque Output & Speed Closed-loop Control for Easy Control
- Not just a new ESC and motor, the new FOC sensors, combined with Intelligent Torque output and closed loop speed control mean the ESC and motor will maintain the motor’s Torque level and
- RPM as the vehicles conditions change. Uphill, down hill, under load, you name it, your Axe system will do what you’re telling it to do.
Battery Reverse Polarity Protection
- Hobbywing's AXE FOC Crawler system has been designed with a very unique feature protecting your ESC from damage caused by Battery Reverse Polarity, so no matter how many times you reverse the battery connections the AXE ESC and the paired motor are safe from damage.
Applicable to All Weather & Track Conditions
- The IP-67 waterproof has been taken to a new level with the AXE System. Completely sealed ESC design with robust heatsink case design ensure the ESC is ready for anything you throw at it. The motor as well, is sealed, and combines a completely new sensor harness. No messy extra steps to make your system water proof.
Dual Running Mode
- AXE FOC Crawler system supports dual running mode, not only classic "Forward and Reverse (rock crawler)" mode, but also "Forward/Reverse with brake (normal)" mode, to satisfy your application.
Professional Drag Brake Adjustments & Super Parking Capacity
- Drag brake rate, and drag brake tuning allows scalers to adjust not only the hill/hold/drag brake, but how quickly the brake applies. This allows high speed driving with out sudden jerks or stops when releasing the throttle. The drag brake itself is super charged, and able to be run at extremely high levels. Compared to a standard crawling brushless setup, the drag brake in the Axe System can be rated at 200% in comparison.
Built-in Bluetooth for Connecting the Mobile APP Directly
- Built in Bluetooth connectivity means exactly that. The ESC has Blue Tooth built right in! Nothing extra is needed to access the ESC’s complete on board programming but your smart phone device and the Free Hobbywing App from your App Store. That’s right folks, the Bluetooth feature is BUILT INTO the ESC. No extra devices, wires or connections required!
Easy Obtain AXE Running Status with Real-time Data Recording Function
- Connect the HW Link cellphone APP to the ESC and open the real-time data recording function, to check the throttle, voltage, current, temperature, RPM and other data in real-time. Easy obtain running status of ESC and motor. Note: Due to transmission distance of bluetooth, the effective distance is about 3m!
Super Internal BEC
- The built-in switch mode BEC with a maximum output of 13A and voltage adjustable between 6V and 7.4V allows the use of various standard servos, high voltage servos and other peripherals.
Built-in High-precision Magnetic Encoder
- A high precision magnetic encoder is used in the motor to ensure precision and consistent information is provided to the ESC. This allows the ESC to have more information from the motor than standard “hall” type sensors and provides improved performance and efficiency.
Advanced and Secure Electronic Switch
- The dust, dirt, and waterproof switch housing ensures a long reliable life for your ESC, will not suffer from the problems most standard on/off switches encounter.
Multiple Programmable Items
- With enough settings to keep your vehicle running “just right”, there are also timing/boost settings, just in case it’s not fast enough, this feature allows you to unleash some extra top speed from your Axe System. Sometimes the trails are long and winding, so more wheel speed is welcome!

Was hopeful…
Was hoping this version would be better, but no. Welcome to the Nite Ize repair center. The pictures show the old version run by LED batteries. Although they claim the balls are waterproof, no. I’ve learned to clean out the contacts and add new batteries to reuse them, but a lot of the time the rust has already formed. The new rechargeable version is more expensive and has the same ‘waterproof’ casing. First charge was good; second charge didn’t even last for our retrieving sessions one evening. Third session on a full
Charge didn’t even last one session. Too much money for the quality. When they work - they are great. Unfortunately, still the best on the market, it it’s just like throwing away money. Innovators???

Works Great! Very bright
My dog and I really love this ball. Bought this so we can play in the field behind our house at night. Tried other balls, like the glowing ones, but they're not bright enough. Other battery powered balls don't stay on long enough and I got tired of looking for them in the dark. This one stays on, depending on the switch setting, either 5 minutes, or indefinitely until it's shut off or until the battery dies. The battery, according to the instructions, should last 10 hours before needing recharging. I've charged it once when it was received, haven't had to re-charge it yet, played with it about 7 nights now 20 min each time and it's still going.
Others have said it's not very durable, but I've found it to be durable enough to play catch with our border collie, haven't had any issues. but I don't let him chomp on it all he wants, just throw it and he brings it back. I suppose if your dog is an aggressive chewer and you let him just sit there and go to town on it, it won't last very long, just like any other ball. We use this ball only at night when needed, and use cheaper balls at other times to increase its life span.

THIS IS A MUST-BUY! If you have a dog--you NEED this ball!
Color: Orange
We have two 18-month-old chocolate Labs (brothers—basically twins with paws). The best time to walk them is early morning or just before dark… which is exactly how we managed to lose approximately 9,472 tennis balls in our cornfield. RIP, brave yellow soldiers.
So I went searching for a ball that didn’t just glow—I wanted one that full-on lights up like a tiny dog disco. Enter this LED ball. Game. Changer.
Our walks are now way more fun. The ball bounces, flashes, and changes colors like it’s auditioning for a rave. People literally slow their cars as they drive past our field just to watch the light show. I’m not saying we’re local celebrities now… but I’m not not saying that either.
And here’s the real magic: when the boys get distracted and abandon the ball (because squirrel), it stays lit so I can actually find it. We also bought a ball launcher from Walmart for about $9, and the LED ball fits perfectly—same size as a tennis ball, just 100x cooler.
This ball is waterproof and mostly floats, although I haven’t been brave enough to throw it into the pond or river because I’m positive my dogs would treat that as a full-scale navy search mission and never find it again.
It’s easy to charge, and even with 2–3 hours of walking daily, I only have to plug it in every few weeks. We’ve had it for months now and it’s still going strong—super durable. We don’t let them chew on it off-walk (because Labs), but during fetch? It’s a champ.
Also—small but hilarious detail—when they catch it, their mouths light up. I have accidentally created glow-in-the-dark dogs.
I love this ball so much I’m buying a backup because life without it is not an option. Best dog toy EVER. Whoever invented this deserves a medal, a parade, and a lifelong supply of tennis balls they’ll never lose again. 🐾💡

DISAPPOINTED
Color: Blue
only lasted 3 months after about a dozen uses. The LED core fell out and now it's totally useless. Not worth the cost at all. Disappointed because my dogs really loved them.

Dog is obsessed with this.
The spa works as intended it lights up at night, which is super helpful for short winter days and for when the snow starts to pile up, it illuminates the snow pile that dog dropped it in so I can find it. I haven’t actually charged it yet. It came fully charged and has been in use for over a week without needing a recharge. We only use it on outside excursions together. I keep it in my pocket on walks in case he needs something in his mouth or an incentive to run a little off leash. I like that there are two settings to the light which I didn’t notice when I ordered it. One will shut off after five minutes of inactivity to save battery, which is really convenient so I don’t have to keep on screwing it to turn it on and off or there’s a second setting where the light stays on until you manually turn it off. We have it on the battery saving mode and we have never lost it. Overall, a really fun toy that even the neighbors, tiny dog who can barely pick it up and enjoys. It’s not really soft for like chewing, but that also means he’s not going to destroy it. It is a heavy ball to throw, but not too bad. One of my favorite purchases for this puppy.
