Flycolor 40A ESC 2-4S Electric Speed Controller 5v 3A BEC with XT60 & 3.5mm Bullet Plugs for RC Drone Airplane Brushless Motors

Works well, as advertised. Reliable component

This is a very high quality ESC. First rate materials. Very well put together. Looks like an Apple watch. I needed an ESC capable of allowing my AeroScout to use a 4S lipo without stuttering. Now it works flawlessly with so much more power.

Muy buena si vino mi paquete y llega mas rápido solo que el producto de los tres cables trifasico deberían ponerlos colores ordenados para no dañarlo y comprar otro.

My new favorite ESC! Worked perfectly out of the box, easy to set up, no performance hiccups. Also very sturdy, these have survived quite a few crashes and worked fine after.

The esc worked great although once thing I have to say is that the direction of motor spin is irreversible. Meaning, this esc cannot support a motor going in both directions. That wasn’t advertised well enough

Adequate speed controller and battery elimination circuit for the brushless outrunner motors for rc hobby.

If your looking for a plug-and-play ESC, I'm sure this would be a great choice. If you need to program the throttle range, brake or soft start there's no audible sound from the ESC. I purchased two neither had audible sound for programing. Unfortunately I returned them both.

Item was shipped and received quickly, and as well-packaged. Hooked this ESC to a 1200KV 295w brushless outrunner motor and FlySky iA10B receiver with 3S LiPo. Upon throttle-up, motor ran well for about 7-8 seconds, then started stuttering, with the ESC and motor both getting hot rapidly. Later troubleshooting found one of the motor leads coming from the ESC was open. Motor still appears to be OK, so was lucky there. Did not open the unit to inspect for internal damage, just ordered a new, different ESC as replacement.
