iFlight has been teasing me with these tempting SucceX 60A ESC with “Metal MOSFET”. Finally they arrived and I get to try them! Is 60A an overkill? What does metal fet do? let’s find out.

They offer two versions, single and 4in1 ESC.

iFlight SucceX 60A 4in1 ESC:

Can someone please tell me why iFlight tried to soft-mount their 4in1 ESC? ;D

iFlight SucceX 60A Single ESC:

It’s great that they have included all the wires, bits and pieces you would need to start building. Maybe some nylon standoffs and screws would be nice for the 4in1 ESC.

  • Current Rating: 60A (burst to be confirmed)
  • Voltage Rating: 2S to 6S LiPo
  • Dimension: 38x36mm (4in1), 30x17mm (single)
  • Weight: 16.7g (4in1), 4.9g (single)
  • STM32 F0 MCU, Runs BLHeli 32 Firmware
  • Built-in Current Sensor
  • No BEC
  • Supports DShot1200, MultiShot and OneShot ESC Protocol
  • BLHeli32 Firmware Target: iFlight-BL32-4IN1

I have to say, these metal capped MOSFET look rad.

What’s benefit with metal capped MOSFET?

While these “metal MOSFET” ESC have a much higher current rating, iFlight also pointed out they run cooler. That’s great news for any mini quad builds, not only the ones that are pushing 60A current draw with each motor. When testing, I will pay attention to the temperature in ESC telemetry and see if that really makes a difference 🙂

You might notice the mounting holes are enlarged from 3mm to 4mm. This is done in order to fit the rubber grommets. However I don’t really get the point of soft-mounting the ESC.

Maybe they want you to soft mount the 4in1 ESC, then you can hard mount the FC on top and not have to worry about it? But there are so many “thick” wires soldered to the ESC, it will probably impact the soft-mounting effectiveness. And the widened holes seem to be fragile.

There is no BEC onboard – In my opinion it’s not really needed anyway, most flight controllers these days can handle direct voltage, and have their own BEC.

The pins in the header connector are: GND (G), LiPo Voltage (V), M1, M2, M3, M4, CUR (Current Sensor), ESC Telemetry (TX).

The construction of the SucceX 60A 4in1 ESC is out of the ordinary. Unlike most other 4in1 ESC’s, which are just a single piece of PCB, the SucceX has one board soldered on top of another. My guess is, additional copper layers are required due to the high current rating. This probably made it easier to manufacture as well. Anyway, the height of the ESC doesn’t seem to be that much taller.

If you are one of those who are uncertain about the reliability of 4in1 ESC, the SucceX 60A single ESC’s are probably the way to go.

In addition to the metal capped FET’s, these ESC are also equipped with a heatsink to help cooling. Half of your ESC is also protected against “prop strike” too (where the prop bends in a crash and hits your ESC).

The three tiny solder pads in the middle are GND, ESC signal (labelled PWM), and ESC telemetry (labelled TX).

There is also an LED on both sides of the ESC, a thoughtful design, making it visible regardless which side you mount the ESC on the arm.

It’s perhaps not the tiniest or skinniest ESC, and yet it only weighs under 5g without wires. A good choice if you are looking for reliability for a high power 4S builds, or even 6S builds, where it’s possible to pull 200+ amps (50+ amps per motor) with high KV motors.

These are going into my next mini quad build along with other new parts I am reviewing. Stay tuned for updates and the build log 🙂
