30A RC Brushless Motor Electric Speed Controller ESC 3A UBEC with XT60 & 3.5mm Bullet Plugs

These are awesome little brushless ESC's, really reliable, durable, easy to program and surprisingly powerful, I like to diy add my own cooling block and seal both ends with epoxy where the wires come out just to hopefully prolong the life of the ESC 🤷 high quality for a great price and fast shipping

Seem to work as expected. Do not tolerate electrical abuse at all.

Definitely give Relectronics.com 5 stars for customer service. For the price this product is awesome I've already bought two of these they work great with no set up require just plug in play ! Unfortunately my second unit was bad when it came in but that happens with electronics so it was no big deal. I contacted RC electronics and they got back with me within the day and sent me a new one really no questions asked they just asked what my problem was.. if I'm in need for another ESC will definitely buy this one again!

otter twin that had factory installed speed controllers that I thought were damaged from water and loss onlow rpm sink which made impossible to fly so I replaced them and same problem...now I need a new OTTER. Escapes were not the problem, back to the drawing board and will replace the Moter

Worked well for me

Delivery was quick and was easy to access the manual via the grid code. Initial hook up on a used older plane went well and seems to work well in the shop. Still have more mods to do on plane and winter to pass to get the real test. But so far so good. Happy with purchase so far.

While the ESC works properly when raising throttle from MIN to MAX and the RPM response curve is almost linear, there's a hysteresis lag when lowering the throttle from MAX to MIN, the RPM stays constant when going from 100% to 80% throttle, then it falls abruptly, then it becomes almost linear again. I tried reprogramming the ESC with the prog card (which I have) and cannot find a mode that eliminates this problem. Flying a quad like that becomes problematic if the RPM response is lagging a lot. May be the reason why the quad crashed in auto mode.

Funciona excelente, lo recomiendo al que le gusten los modelos eléctricos a radio control

Very good SBEC. It really does not get hot so it is a true Switch Mode BEC. the online instructions and information is accurate and very helpful. I have many of these with no problems.

Just a good esc, nothing to it

GOOD

programmable brake function is a great feature for some application

The item complies with my required specifications & is exactly what I had hoped for. Good value!
