Afro 20a Race Spec 4-in-1 Esc and Cc3d Flight Controller Review
Hither are some of the all-time FPV drone ESC's on the market. There are more to consider when choosing ESC than merely current rating, some ESC come up with key features that improve functioning you don't want to miss out on.

- ESC Firmware and Protocols Overview
 | I compiled the specification of all ESC's for mini quad in this spreadsheet and so you can compare them more than closely |
What key features to look for in FPV Drone ESC:
- Runs either BLHeli_32 or BLHeli_S firmware
- Decent noise filtration – earlier really testing them, if y'all meet lots of capacitors on the ESC, it's always a good sign
- Bigger MOSFET's usually ways the ESC tin handle higher voltage and current, making the ESC more than robust and capable to withstand abuses. MOSFET size is peculiarly important for loftier voltage rigs such every bit 6S due to the higher voltage spikes
The functioning difference betwixt BLHeli_S and BLHeli_32 is minimal, then it actually doesn't matter which one to become. Both firmware now support Bi-directional DShot Protocol, which means you tin use RPM filter in Betaflight with both types of ESC. However BLHeli_S requires flashing tertiary political party firmware to have those features (then slightly more piece of work), while BLHeli_32 but works out of the box.
Too, BLHeli32 is the newer generation and offers advanced features that BLHeli_S doesn't, such equally ESC telemetry, custom startup sound and RGB LED support. Get BLHeli_32 if you desire your ESC to be more time to come proof, or get BLHeli_S if you want to salvage some coin.
Regardless the corporeality of filtration on the ESC, you should always solder extra capacitors to the ability of your ESC, this will reduce the chance of getting noisy FPV feed and improves flight operation. Have a look at this tutorial where I explain why and which capacitors you should use.
Sometimes it's easier to just buy a whole stack instead of picking the flight controllers and ESC separately. This is skilful because you usually don't have to worry about wire connection, they should be plug and play. FC and ESC from different manufacturers might have different pin out so yous accept to double check before connecting them to avoid frying your FC. Take a look at the flight controller stacks I recommend.
The Best 4in1 ESC
4-in-1 ESC'due south are getting more than and more popular these days due to the compact form factor and ease to use past putting 4 private ESC'south on a single board. This results in less soldering and wiring due to fewer solder joints. 4in1 ESC commonly sits under the flight controller, and connects with just one wire harness. Nonetheless the downside is that if ane of the ESC's breaks, you will have to replace the whole board which is more expensive.
If your 4in1 ESC and flight controller are from unlike brands, you must cheque pinout before connecting, or you lot can run a risk burning your FC or ESC. Make certain you bank check and swap the wires in the harness if necessary before connecting.
Holybro Tekko32 F4 Metal 65A 4in1 ESC – Top of the Line
Production Folio:
- GetFPV: https://oscarliang.com/production-2lkt
- Banggood: https://oscarliang.com/product-vkn2
- RDQ: https://oscarliang.com/product-onoj
- Amazon: https://amzn.to/346eCJh
Probably the nearly sturdy and lowest noise ESC on the marketplace with that shocking corporeality of noise filtering onboard. Information technology'due south amazing how clean the ability is when using this ESC. The Tekko32 Metallic is using the currently well-nigh power F4 processors in an ESC, information technology's rated for 65A, with 85A burst current. It'south a swell choice for both 4S and 6S, freestyle and racing builds. Run across this review for more detail.
Racerstar REV35 4in1 – Cheapest Worth Having
Product Page:
- Banggood
- Amazon
The Racerstar REV35 35A 4in1 is one of the cheapest 4in1 ESC on the list. Interestingly it looks identical to the Holybro TekkoS 4in1 we previously recommended, information technology's highly likely to be a rebranded product, and I loved the TekkoS 4in1 before they discontinued information technology. Note that it doesn't take whatsoever solder pads so you would accept to apply the connector.
XRotor Micro 60A – Tried and Tested
Product Folio:
- RDQ: https://oscarliang.com/product-bu6r
- Amazon: https://amzn.to/34se7cw
- GetFPV
The Hobbywing XRotor Micro 60A is probably i of the most recognizable 4in1 ESC'southward in the industry because it's endorsed past many peak pilots. It's a feature-rich ESC: DShot1200 support, beefy FET'due south, directly pins for low ESR capacitor, and you tin either use the connector for a plug-n-play setup, or direct solder to the flight controller. If budget isn't an upshot for you, this is a serious contender to consider.
Aikon AK32PRO 50A – Powerful yet Meaty 20x20mm
Production Page:
- RDQ: https://oscarliang.com/production-pymy
- GetFPV: https://oscarliang.com/production-ltzs
These have very compact course gene (20x20mm mounting holes). Don't be fooled past the small size, they actually take the aforementioned operation equally some other 30x30mm boards, with 50A current rating per motor output, and supports up to 6S! It's small enough to fit in 3″ builds. If yous ever demand a 20x20mm 4in1 ESC for even a calorie-free weight 5″ build, this is a slap-up option.
The All-time Individual ESC
If you use individual ESC'southward, make sure to purchase an "all-in-one" (AIO) style FC.
Spedix IS30 ESC – Cheapest Worth Having
Product Page:
- Banggood: http://bit.ly/2YGPZur
- Amazon: https://amzn.to/2M6xrCf
These are some of the oldest ESC on the list, only they are inexpensive ($10 each) and become the job done. The Spedix IS30 ESC runs BLHeli_S firmware, support DShot600 and 4S, and they accept decent performance (low racket). Great for a budget build.
Racerstar RS30A V2 – Cheapest Worth Having
Product Page:
- Banggood: http://bit.ly/2lNbzNi
- Amazon: https://amzn.to/2IlYJQP
The Racerstar RS30A V2 is another budget ESC's I'd recommend, and the quality is actually quite decent. It runs BLHeli_S, supports DShot and Multishot out of the box without any modification.
These are actually but rebranded Cicada 30A and there is a smaller 20A version if you are looking for slightly lighter ESC'due south.
The Racerstar RS30A V2 is capable of running DShot600 ESC protocol and supports 2S-4S input voltage.
Holybro Tekko32 35A (Peak of the Line)
Production Page: (Discontinued)
Frankly most BLHeli_32 ESC perform kind of the same, what makes them stand up out is their reliability. The Holybro Tekko32 35A has been very reliable during my time of testing them. Build quality is top notch, and the solder pads are well sized, you can even solder on both sides of the board, making it very easy to piece of work with. Every bit you tin see there are many capacitors onboard for racket filtering, and they are indeed some of the all-time performers when it comes to noise.
The TekkoS32 35A weighs only 5g, supports 2S to 6S input voltage, and there are born RGB LED'southward.
I know Holybro has released a newer F3 version, but I simply can't bring myself to recommend them over this ane. The F3 35A version is much cheaper, but has piddling noise filtering onboard, while the F3 65A version is much beefier, however it's $vii more expensive (each), and bluntly 65A is an overkill. The F3 processor is faster than the F0, merely it brings fiddling to none improvement in performance. With that said, if you are going for 6S, perchance consider the F3 65A version if you accept the budget :)
Aikon AK32 35A ESC (Tried and Tested)
Purchase:
- GetFPV: http://bit.ly/2F8TLqh
- Amazon: https://amzn.to/32nKnKK
I used the AK32 35A ESC's on a build for months and didn't accept whatever issues with them, great reliability and operation. These are elementary and manifestly BLHeli_32 ESC's without whatsoever fancy RGB LED'due south. The Aikon AK32 35A ESC is rated for 2S to 6S voltage, and the burst current rating is up to 45A (10 seconds).
Conclusion
To be honest about latest ESC'south these days perform similarly well, it'due south difficult to go incorrect with whatsoever of the choices mentioned.
