A favorite of drone racers and freestylers alike, the Hobbywing Xrotor 4in1 ESC is a reliable ESC you can depend on. The Xrotor 60A 4in1 is known for its reliability, especially in high power applications. This ESC runs on all of the newest hardware and firmware: 32 bit BLHeli_32 with DShot1200, 60A rated MOSFETs and circuitry, and easy-solder pin holes for a capacitor.
To make building easier, there is a connector that houses the ESC signal wires, current sensor, and battery voltage to connect straight to the FC of your choice.
The ESC is also soft mounted with rubber grommets to minimize vibration noise from reaching the gyro! This allows pilots to use minimal filtering in Betaflight and maximize performance.
Features:
High-performance 32-bit microprocessor with the running frequency of up to 48MHz for excellent performance.
BLHeli_32 firmware is the third generation BLHeli, following base BLHeli and BLHeli-S.
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 environments.
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 leastDshot1200. 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 throttle. This can be very useful for finding lost crafts.
Onboard 5V BEC, powering different accessories such as FC, VTX , Camera, LED lights and etc.
I bought 3 Speedybee stacks a ways back due to the inbuilt Bluetooth feature of the FC. Then there was/is a hardware problem with the ESC. Speedybee was then sending out Hobbywing ESC as a replacement. That is all you need to know really.
Right away, this is the best 65mm Whoop I know. Not even close.
I ordered two, one is more or less stock, just the PEEK motor screws and V3 cockroach. The second is upgraded to 0702 27000kV but will go back because I like the 25000kV more because of smoother throttle response and perfect betaflight tune.
Now the but:
1. On both quads I had to replace the BeeEye for a spare one because both are out of focus.
2. the yellow props were way too loose and very brittle. I lost two on my maiden. Black, blue and red are very tight (too tight for such a fragile prop) but if you get them on without bending them, they will last.
3. why does the quad not come with the lighter frame right away?
4. PH2.0…. You know the drill.
On that price point, even after the frame and PEEK upgrade I can forgive these quality issues. Especially considering the great tune and quality FC and motors. But be sure to order a replacement cam and props right away.
This was kind of a late night lark. I'd seen this upgrade for the Mk3 for a while and pondered whether it was a gimmick or not, and I'm pleased to say it's a genuinely good upgrade. It has reduced the noise of my Mk3 considerably. I haven't noted any significant increase in print quality, but the old drone of the bed is gone and that's completely worth it.
