HOBBYWING XRotor FPV G2 45A 4in1 and XRotor FPV G2 65A 4in1 are highly integrated, high-performance electronic speed controllers for FPV racing drones. This firmware upgrade replaces the legacy BLHeli-32 with the latest AM32 firmware, bringing advanced features and comprehensive functionality. FPV drone pilots can tune ESC parameters and complete firmware updates via multiple methods, including throttle signal cable, development board, and Betaflight-compatible flight controllers.

The new Hobbywing 45A 20*20 4in1 ESC comes with the same reliability of the bigger version Xrotor 60A 4in1 in a smaller foot print and 20mm mounting pattern making it one of the best options for ultralite race frames like the Floss 3.0 lite.
We witnessed this ESC being punished first hand by the French Champion Killian at the WDC race in Turkey.
This thing is SOLID!

Pairs perfectly with the new Hobbywing F7 Flight Controller!

By adopting the open-source AM32 firmware, the XRotor FPV G2 45A & 65A 4-in-1 ESCs benefit from faster update cycles and continuous feature expansion, compared to the closed-source BLHeli-32 firmware. Besides, enhanced compatibility and stability gain ensure exceptional and consistent performance for FPV drone racing.

Higher Power, No Load Worries

The AM32 firmware enables ESCs of the same specifications to sustain higher power output, handling high-load scenarios with ease and providing stronger power support.

Precision Tuning, Quicker Throttle Response

The motor KV value can be entered on the tuning page to finely adjust the motor's response speed and low-RPM acceleration, ensuring more precise control.

XRotor FPV G2 45A & 65A electronic speed controllers adopt next-generation 32-bit ARM F4 MCU running at 120 MHz for ultra-fast computation. In further, these ESCs support variable PWM Refresh Rate from 48 kHz to 96 kHz with dynamic auto-adjustment, delivering smoother throttle control.

Highly integrate four high-performance ESCs in one, XRotor FPV G2 45A & 65A ESCs feature built-in voltmeter which allows flight controllers to monitor the amp and voltage in real time.  The shock-absorbing design of mounting holes effectively reduces the external vibration’s impact on high-sensitivity components and provides great shock-absorbing protection to upper devices (i.e. FC).

Features:

  • High-performance next-generation 32-bit ARM F4 MCU running at 120 MHz for ultra-fast computation.
  • open-source AM32 firmware
  • All codes use damped light mode. Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling.
  • The code supports features to prevent sync loss. There are tunable parameters that can make the code run well even in the most demanding situations, although default settings will work excellently in normal operating environment
  • The code supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and Multishot (5-25us).
  • Dshot signaling is supported at any rate up to at least Dshot1200. The input signal is automatically detected by the ESC upon power-up.
  • The code also supports a beacon functionality, where the ESC will start beeping after a given time of zero throttles. This can be very useful for finding lost crafts.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.

It doesn't work.
Color: Blue
The two halves of the ball shell come apart again and again when the dog plays with them. When it is time to recharge the core, it will not take a charge. The dog loves it, but it's unsafe to play with.

It doesn’t do what is supposed to do
Color: Blue
Wasn’t impressed..,all the ball does is vibrate. It doesn’t really bounce

My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.
