Dshot ESCs from reliable brands

Hello All,

First post here. I’m looking to build a single motor fixed wing, and have most of the components picked out for the build. I’m having trouble finding ESCs that fit the bill though. I’m looking for something around 30+ amps continuous current draw on a r4s battery. But I would also like it to support Dshot and have some passive or active cooling because it will be mounted within the fuselage and im really not sure how much airflow it will be getting. I was looking at T-motor ESCs but they have been sanctioned. I was really interested in the hobbywing platinum pro 40a but i cant find any mention of dshot support so im assuming its just pwm. I took a look at castle creations but they are out of the budget and also have no mention of Dshot. It seems like finding a reputable Dshot esc is quite hard, but i can find plenty of chinesium versions on aliexpress. I like Dshot because of the checksum and response but im seeing mixed opinions on getting ESCs that support it. any reccomendations for escs or advice on choosing one?

Thank you!

What do you mean by that?

The problem is there are not a lot of single Dshot ESC’s. Plenty of 4-in1’s. TBS, Lumenier and Holybro (Tekko) make AM32 versions if you can find them but they will need some airflow.

I guess ill have to search around some more then, i was looking at the list of am32 compatible hardware and it was pretty small so hopefully i can find something in there to fit my needs.

As for T motor in the U.S. atleast:

The U.S. Department of Treasury’s Office of Foreign Assets Control (OFAC) recently announced sanctions against Jiangzi Xintuo Enterprise Co. Ltd, operating as T-Motor, a major global supplier of rotor components used in UAS platforms.

The development follows the Department of Commerce’s 2024 decision to place T-Motor on the Bureau of Industry and Security’s Entity List due to the company’s involvement in supporting foreign military capabilities.

Recent actions by the U.S. Federal Government reflect growing concerns about supply chain security and U.S. national security objectives. T-Motor’s listing on the OFAC sanctions list restricts its operations and limits its access to U.S. markets and technologies.

Ah, that. I think the only T-motor ESC’s that supported Dshot were 4-in-1’s anyway.

That seems to be the case, you are right. I think I will probably go with a hobbywing platinum pro based on the use case. Dshot would be nice but it seems like most single ESCs by reputable brands dont have it, so standard pwm should be fine i guess.

Here are some.
TBS
Lumenier
Holybro Tekko

All multirotor ESC’s but with some airflow they could work.

Thanks! I’ll probably go with the lumenier unless you think the others have higher quality mosfets. It has the metal capped fets with an included heatsink so that should atleast partially help, and ill work on the airflow issue.

I did some more searching, ever heard of Neutron RC? NeutronRC 70A-G071 V2 2-8S AM32 Dshot1200 X-Class Single ESC Support Current Sensor / Telemetry output Crawler Part - NEUTONRRC
Im interested because it seems they use real infineon mosfets with metal caps compared to the others linked.

They seem to be on the website this in one of my top choices,

Buy them from local US sources while they are stock.

I got mine on Amazon a few months ago. No longer there tho. odd.

Not odd. The US domestic suppliers cannot re-supply. They are mostly out of stock at the big stores (Raceday Quads, GetFPV, etc).

Odd as to what’s the issue? all of the sudden Amazon is out? That seems normal to you?

Chinese New Year is over. lol

T-motor/JIANGXI XINTUO ENTERPRISE CO LTD has been sanctioned in the US for supplying components to the Russian Military.
Sanction
Nobody can import their products. But, they can sell what they have.

Ok that makes it clear. Thanks.

Hey i too was in this situation

The major difference is update rates and the telemetry some dshot esc offer
someone advised me as for fixed wing the standard esc would work just fine and there would not be a large noticable difference unless it’s a high kv fpv multicopter designed for acro(highly manueverble)

And if you’re using it for telemetry like current sensing and rpm data

just know most modern flight controllers designed for wings(fixed wings )offers onboard voltage and current calculation with dedicated measurement device unlike assuming the current from voltage drop like most of the esc does (some have dedicated current sensor).

I believe rpm telemetry can be compromised in this build as for fixed it would not be as important as compared to multicopters

It’s true that most digital esc are relatively more more efficient and lighter in a very small degree

So my take is if you can’t find the esc of your specifications or its stupidly expensive don’t hesitate to use the normal branded (i repeat branded )esc

It’s just an advice by my experience let me know if you need any help.

Over and out

I’ve switched to the Tekko32 F4 45A ESC the last few years. I’ve been using them in mapping quad and hex rotors, but even my sonar boats. RPM and current monitoring with bidirectional bdshot comes in really handy with my boat. I doubt the diy esc coolers in the pic are really needed, I just felt like doing some 3D prints.

Who cares about sanctions, buy T-motor products from Aliexpress, they are genuine.

Also, why do you need Dshot for plane? The only reason could be to get RPM and Temp. But ESC designed for planes usually have the freewheeling, which is much more efficient, and the copter ESC do not have it.

If you are on a budget, just get any ESC, like Speedybee 60 4x1, it will have Dshot if you flash it with Bluejay, and will run to about 30…35 Amp continuous.

No airflow cooling, guaranteed ESC overheat, any brand.
