Readytosky 50A Bidirectional Brushless ESC Electric Speed Controller | Electric Speed Controller for RC Car Boat Underwater Propeller

Update to this review: ReadyToSky was good enough to send me a new ESC, even though it was out of Warranty. Thankyou!! I tested the new one provided by ReadyToSky, and it works perfectly! I am grateful they responded so quickly to help my situation! I will try out the new ESC once I receive it, and update review accordingly. I wanted to like this, but I shorted out and almost started on fire the first time I tried to use it. I bought two of these. One worked fin

First few water cooled speed controls i bought had no revearse so boat couldnt flip if flipped.

For buyers that are building a drone/plane, beware that it is a Bidirectional ESC that doesn't have a calibration mode.

Muy buen control de velocidad, arranque y precisión. Lo uso en unos Rc echos de hoverboard y aguantan muchísimo.

These thing are awesome I have two of them for a project and they haven’t caused me trouble yet

I received it, put connectors on it. installed it and it immediately smoked my motor on 3s. I didnt even have a prop on it, my motor just went up in smoke. Now i need a motor too.

If something seems too good to be true, it likely is. You'll be hard-pressed to find a 50A rated bidirectional ESC like this one at this price. I need 4 symmetrically bidrectional ESCs for my project. This is actually kind of hard to find. Most bidirectional ESCs seem to supply more forward current than backwards. I bought 4 of these ESCs to use with some Turnigy XK2845-1980KV motors and a 4s battery. Under no load, just experimenting with control signals, everything seemed great. But the slightest amount of load led to the motor getting smoked (i.e. the coils got so hot they melted the enamel leading to shorts--this kills the motor). I thought this was just random chance, so with another ESC and another motor I did the same test and smoked a second motor. They're twitchy--as far as I can tell my PWM signal is stable (using a micro controller and hardware PWM) yet at neutral throttle (50hz signal, 1.5ms on-time) they are twitchy. Further testing, same set up as before, all components within spec, led to the ESC entering a boot-loop (the start up chime kept playing over and over) before the ESC literally blew up. One of the big electrolytic capacitors blew. Others clearly report better success than I--I'm new to the hobbyist motor/ESC game so maybe I've messed up something royally and don't know it. But caveat emptor--I burned up two, nice, relatively expensive name-brand motors that are perpetually out of stock now and cannot replace.

I bought this Bidirectional ESC to use for a school project and it didn't even come with a manual. I even emailed the manufacturer about obtaining a manual and never got a response. Its startup is terrible and gets hot way too fast. I do not recommend using this ESC at all. I recently bout the Shark G2 60 Amp esc and it works wonderfully.
