I have bought one of these speed controllers to go with a brushless motor as an experiment with using such kit in a boat. I set up the controller with the battery pack, motor and receiver on the bench and programmed it for what I wanted it to do using the Hobbywing ESC programming card and it worked perfectly.

The controller is now installed in the boat, correctly connected to the battery pack, receiver and motor but will not operate the motor. When the battery pack is switched on, a green LED lights inside the controller and the rudder servo operates as normal which indicates to me that the ESC has power and that the BEC circuit is working. However, the ESC does nothing (no ‘beeps’, etc.) and the motor will not work at all. Attempts to use the programming card gives no help as the LEDs on the card do not light up.

I have tried (three times) to e-mail Hobbywing for assistance, but received no reply at all.

Has anyone else had problems with this kit and can help me out? Can anyone suggest what I may be doing wrong as a mere beginner with brushless kit?

Also, the total lack of reaction from the manufacturer to a simple technical query suggests that they couldn’t care less about their customers – so beware!

Hi Phil I have Hobbywing seaking series brushless combos (2) both of which run ok. The first attempts were a bit iffy until I got used to the new technology.

If you have no tones at all, I would check the connections to the motor, (it is the motor that actually makes the noise, not the Esc).

Depending if you have set fwd/rev or fwd only make sure your Tx throttle stick is in the correct place (the stop position) before switching on the Rx setup, if not the Esc will not set up and bleep. One of my problems was throttle stick needed to be reversed I was switching on with full throttle.

Other things to watch is the wiring between battery and Esc this should be as short and possable and not thin wire. There are some usefull info about this on Astec models forum site.

hope this helps

Thanks for your suggestions. The wiring from battery pack to ESC and ESC to motor is correctly sized and as short as possible. I have tried the ESC with another motor – no go. I also tried the motor/wiring on another ESC and it worked fine. The ESC was programmed for forward/reverse so throttle in the middle should be the correct spot – tried with two different transmitters but without success. I have also tried the ‘Begin to use new transmitter’ procedure in the Hobbywing manual and that doesn’t work either!

I have now been in contact with the supplier of the ESC (an eBay shop called egrandmart) and they are being very helpful in talking to the factory on my behalf – even they say that Hobbywing do not talk to customers!

I was asked by the eBay seller to return the ESC to them in China with a covering letter to say what was happening. Within a week or so (limited by the speed of the postal service) they advised that they had been told by Hobbywing that tests showed that the ESC was faulty owing to loss of program. I now have a new unit as a replacement – brilliant service from the supplier!
