DYS 30A 2-4S Brushless ESC with 5V/2A BEC with XT60 & 3.5mm Plug for RC Fixed-Wing Aircraft Helicopter

This is a good, basic, ESC. First time you power it up, it will beep at you and do nothing else until you calibrate the throttle (i.e. go from zero to full and then back again.) Once you do that, it remembers the calibration and works as it should. It's a nice little safety feature, and I was surprised to find it in a no-name ESC. Throttle response sounds correct, and the BEC seems up to the task of powering at least four servos and a telemetry-capable receiver.

It work just the way it should! No bad issue at all. And at htis price,It's a great deal!

It beeps the incorrect cell count, but if works great!

Hooked it up and it powers on my plane but will not power up the motor. And makes the motor beep like crazy, no matter how the motor is hooked up. I got a different esc and it powers my motor just fine. Will not buy again. I give 0 stars if I could. Was a waste of money.

Full 3 parameter selection for most settings, reverse function as well, cannot be beat for the price, holds up to full throttle at 14amp draw continuous from 12.6v to 9.6v, heat sink gets pretty warm but it never hit temp protection mode. Waterproof ends with hot glue if using for boat or float plane. 9 flight hours so far, no issues or signs or failures. Even works under water and will propel plane at low rpm through water when upside down. Strong little ESC.

Worked great until it popped and smoked on the 3rd use (~20% throttle). -3S/XT60 2200mAh Battery -R12F RX -T12D TX

This has given me months of trouble free use. Very good ESC and beats the sticker shock of other name brand stuff. These are the only ones I use in my planes.

Work great. I recommend these.

Good budget ESC. I've been running it pretty consistently at around 55amp max on 4s (not certain how it would sustain at 80A). Seems pretty necessary even at that level to have adequate airflow as it often comes back quite warm.
