What is to top limit for the voltage to this esc, can it be used with a 4S LiHV Pack?
David  8 points - 7/27/2016
I used the programme card to programme the ubec.I then connect it to the reciever turn on transmitter then connect the battery to the esc/ubec. the ubec b***ps singular beeps then goes on to make various other beeps /tunes. when i put the throttle to full, ubec beeps twice then nothing. move throttle back down ubec fails to operate motor. What is wrong?

Can you tell me when my ASW 28 and Hummer will be in stock? I have been waiting for a month now!

For question like this you might be better off ask the HK CS people,look to the top of the page on the right hand side and look for live chat,click on it once you have log into your account and follow the on screen instructions,this comment section here is for questions on said product and it isn't often monitored by HK staff,it's mainly other HK customers like me who will answer question here,hope that helps you and you others out a little.

How long till the axn floater is in uk stock thanks
 Tank1 1086 points
I know this is coming late but they are in stock now and if you ever need something else from HK and they don't have it in stock,add it to your wish list and HK will then send you an email to say they become back in stock,hope this helps you and others a little. PRODUCT ID: AXN-clouds add the last part to the HK search engine and it should pop up with the AXN.

Hi Hobby King Great News that you you've opened in the UK!. I have a CX20 Quadcopter. what gimbal and camera would you suggest? , middle price range and good resolution and do you have it in stock? Thanks Allen McMurtry

Hi Allen, not worth asking questions for Hobbyking to answer as they do not monitor the product discussion pages, best to ask live chat or go to the hobbyking facebook page and ask there as then they will answer. . . . . . . .Regards Poppy Ann.

Great little ESC and does what it says on the tin so to speak,it is just as good as the Turnigy Plush ESC in my book,i have both this one and a few plush ESC's in a few of my warbirds and this one seems to work just as well as them,so no complaints this end and if your going to try and run this little baby at it's max amps make sure you have good air flow as you would any other ESC,to be honest no one should really be pushing any ESC to it's max as you really should be going higher,so if you motor is calling for a 20amp ESC go at least another 10 amps more to be on the safe side,that way you shouldn't have any problems and you won't have to worry about your ESC if your pushing the motor at WOT most of the time.
For the price we can't go wrong and i'll be buying a lot more of these when i need too as i'm always using a lot of 30amp ESC's these days.
