HobbyKing 30A Boat ESC 3A UBEC

I bought 4 of these over the last 12 months and just got round to using them. 2 of them work fine, of the remaining 2, one worked fine then crackled and spewed smoke out and the other cut out and stopped working as soon as I applied full power (with no load on the prop in both cases). I only used a 2 cell lipo (2300Mah) battery and these are supposed to take a 4 cell. It would cost me more to return them than what they are worth. Not good Hobbyking, you look like loosing customers at this rate.

VERY DISAPPOINTED WITH THIS PRODUCT. I BOUGHT THIS AS A REPLACEMENT FOR THE HOBBYKING HYDROTEK F1 AND IT EXPLODED AS SOON AS THE BATTERY WAS CONNECTED.
CHEAPLY MADE PRODUCT IN MY OPINION AND NOT DURABLE.I WOULD NOT ADVISE ANYONE TO BUY THIS PRODUCT.

great product with a great value

Wszystko OK
Działa jak powinien zakupiłem łącznie z 20 sztuk i zero problemów
Stosuje go z Akumulatorem PB12V 12Ah
Nic lepszego za te pieniądze się nie kupi .

Work well, nice value for money esc

Not a bad esc for the price, but it does seem to get a bit warm when in use. I use this for a tug boat application so over all it seems good for now.

this is a very high quality product at a very good price. It can handle the current very well with almost no heat. it is a bit chunky making it hard to find space in a smaller model but with some time and effort it should fit in almost anything. The watercooling system is very easy to attach and the manual gives a very detailed specs of the ESC. with plugs pre-installed it makes your job alot easier and saves time. you will have to put on your own bullet connectors though but this i very easy and doesn't require any soldering. .

Love the fact that its completely sealed and works great with a bl2848sl .

For the price, this is a very good ESC for small size boats. It has reverse functionality with set speeds so if you are using it with a flex shaft it should not unwind it.

It's almost completely sealed (only part that is expose is the capacitors) so there is no fear of this getting wet. It has two water inlet and two outlet. If you have two water pick-up on your boat then you could use both ends or you could just loop one side with the other side.

It doesn't come with terminal connectors on either the battery lead or the motor lead so you have to either have these already or you purchase it at the same time. Most small size motor uses a 3.5mm gold connector so I would suggest to get this.

With the exposed capacitor, you can purchase liquid tape and cover this completely so that you have no fear of using your boat in salt water. Make sure you also use it on the back of the battery terminals and motor terminals.

nagyon j termk n meg vagyok vele elgedve!!!
