H-KING 20A Fixed Wing Brushless Speed Controller

H-KING 20A Fixed Wing Brushless Speed Controller


Designed for planes only, the H-KING ESC are an excellent choice for any plane requiring linear, sharp and reliable throttle response on a 20A ESC.
H-KING speed controllers have strict end-of-line QC testing and are SMT (Pick-n-Place) in the same room as the through-hole soldering(wires, capacitor) and packaging is done. Improving quality and reducing contamination and inconsistencies due to transportation.
The H-KING Speed Controller includes a 2A BEC (Battery Elminator Circuit) to power your receiver, there is no need to have a seperate receiver battery.
The H-KING range of ESC are both economic and reliable. They are pre-setup with LiPo and auto cell detection so you can just plug it in and fly!

Basic Spec.
Amp rating: 20A
Burst Rate (15sec): 25A
BEC Current: 2A, 5V (Linear)
Voltage: (2-3 cell Lipo)

I'm a newbie. What connectors would you guys recommend I use to connect this ESC to my motor and battery. I purchased the Bixler 1.1 ARF.

Hi all. I bought a new one of these with my Bixler 2 ARF. Sometimes it'll run smoothly and other times it'll just pulse the motor and it won't start/run. I've tried another ESC, but that just cuts out at 1/2 throttle. Not happy. Can you help, please?
Pierro  1 points - 4/21/2013
 
First I programmed my motor controler (H-king 2s/3s lipo, 20 amp.) with my k-king programing card (auto lipo, forward, no brake). Then I wanted to test my motor with these settings. So with the connectors of the controler connected to the throtle signal I turned the transmitter on and then I pluged the battery pack to the controler. At that moment I hear the continuous repeating beeps without end. Whatever I do with the stick nothing changes, no reaction and continue beeping. I tried that many times with the stick in different positions. I'm using turnigy motor D2822/14 1450KV. Can anyone help me? It's the first time I trie to control un brushless motor. Thanks!

i got the airboat artr and a 19.00 2.4 ghz ground radio.with this esc the prop will only stop if i go all the way to brake position on the radio.
Ryan  1 points - 1/15/2013
 
After I programmed this esc with the brake setting turned on by mistake. After the programming finished I wanted to reprogram but there was a sound repeating and non of the controls on my transmitter worked even though it's connected to the receiver. The sound sounds like the first sound it starts up with without the battery count beeps. What should I do?
 Pierro 1 points
Hello, Have you found how to solve your problem? I have a similar problem. It is continuouly beeping and nothing works. My transmitter is correctly bound (i have checks with servos). If you can help, thanks.

Hay guys do you recommend to add heat sink with this esc ?
 BernardoUruguay 261 points
Ig f your power requirements are near 20A then I would recommend you to buy a bigger ESC (maybe 30A). This leave it as it comes. Please credit me if this is useful
 Youhaan 70 points
no, it is too this and already has one

Hi folks, I'm beginner in electric planes... and i would like to know if this ESC can be used with this 25C battery (Turnigy nano-tech 2200mah 3S 25~50C Lipo Pack) http://www.hobbyking.com/hobbyking/store/uh_viewIte

 BernardoUruguay 261 points
It should work fine. But I would recommend you to gor for 30A blueseries or Mystery. They are much better quality and you´ll be on the safe side

hooked it to my new bixler and everything was working but it smoked. I unpluged right away and note a small burn hole just below the black power wire. wass up?
 Arman 375 points
Hi david the bixler motor uses 20 amps and when u hook it up with a 20 amps esc it wont work. Your motor needs some spare amps. You better use a 30 amps esc. And dont fly anymore using this esc. It can catch fire!! I use this esc: TAE-30A Youtubeee/user/nonamerc Give us some feedback and subscribe if you want to.
 TechnoFinder 126 points
no smoking please...lol well i guess the amp draw is too much

 Arman 375 points
Hi onkelz. The bixler motor uses 20 amps. And when u hook that up with a 20 amps esc your esc will burn. I use a 30 amps esc and it works just great. So dont use this esc! Use this one: TAE-30A /user/nonamerc Give us some feedback and subscribe if you want to.

 marvin8888 139 points
after the first beep try the throttle at middle stick. or configure it on the subtrims of your radio
 TechnoFinder 126 points
move your channel 3 throttle position to the lowest point and also the trim position to the lowest position
Stanciu  5 points - 12/11/2011
 
From 30 to 30 seconds ESC makes a beep sound. Only when the throttle is zero. Is it normal?
 jim 5 points
Yes, the beep is telling you the esc has armed.

 BernardoUruguay 261 points
Don´t use it!!!! Will blow up inmediatly. Besides you need more amps and a watercooled esc

can you set the timing on this esc?
 Ettore 6 points

 MarceloMMY 93 points
NO , it cant be . This ESC is pre-setup .Look at the description of the ESC.
BEST ANSWER CREDIT AWARDED
 munsaf 293 points
No, no settings for timing. It has only 3 basic settings - LiPo/Nixx cell recognition, prop brake on/off, and forward/backward rotation direction. I'm using mine with a 3000kv outrunner w/4.75x4.75 prop on 3-cell lipo and it performs flawlessly, so wouldn't think timing is an issue. Hope that helps.

i have one of this ESC, i use it with BL 2408. first time tx on then connect batt to ESC. until beep hear it.after that throtle up slowly until top position, but BL motor dosn't run. I try again but still same.can any one help me???for my case??thx
 Meinschein 13 points
veja se os fios do motor estão ligados corretamente.
 distractor 106 points
Throttle channel reversed? You should also program the min and max throttle position with any new ESC.
 Leandro 10 points
tente inverter os fios. pode ficar tranquilo que nao queima o esc.
 sonnydc 118 points
Same thing happening with me. This esc just continuously cycles in the setup and doesn't arm/power the motor.
guill3  5 points - 7/11/2011
 
Does it come with the battery connectors?
 boingk 265 points
No connectors are supplied, you must buy them seperately. I'd recommend either the female JST or XT-60 connectors that are on most batteries sold by HobbyKing.
BEST ANSWER CREDIT AWARDED
 Tony 3 points
No connectors are included, you will need 3 for the motor side (unless you are hard wiring the ESC to the motor) and your own choice of battery connector. I would recommend EC3, Deans or XT-60, but any 3.5mm fitting would be fine.

Has anyone experienced any unusual heating with this ESC? I have one of this and it seems working but it gets considerably hot even when the motor is off. (Servos connected and at neutral). Is this normal for this ESC?
 Meinschein 13 points
tenho 2 peças, parados não esquentam não, de qual temperatura estamos falando c°?
 boingk 265 points
No, it shouldnt do that with no current load. I would check to see if you are getting a current short between two wires or if you have connected the battery incorrectly.
 papa_lazerous 56 points
It will produce heat regardless of load due to the BEC being a linear type rather than switched it is lowering the votlage from the battery pack to what is needed by your radio gear it produces heat doing so. A good switched type BEC would be more efficent and produce very little heat. I have one of these and it gets hot but works fine
 Ktech 4 points
If no there is no charge load it shouldn't heat up at all.

these are good esc i use about 20 of these in my planes (10 to 35 amp) all seem to have zero timing issues. if you tweek your motors and timing becomes an issue go with next level programmable esc not these

motor stutters a few seconds and stops.
I followed instructions on file here and reprogrammed ESC but still same.
Is it bad motor or bad ESC?
How do you change speed on ESC progrm?
 H-KING_SCOTT 5238 points
Check soldered connections, that sounds like possibly a dry joint.
 Mike 4 points
i dont know if its a bad esc but when i only plugged it in and a few seconds later it caught fire!
 cesch01 40 points
Proba el motor en otro bec si funciona el motor tenes el bec roto,revisa las soldaduras,que estas esten brillosas,una mala soldadura no brilla.CES

I can't get the brake to work, came with my Ventus Glider, said it had a brake.. Any one have a fix?
 p51p51 44 points
Remember to move the throttle to half position during the programming sequence. Start with the throttle in the full position then when the programming beeps start move the throttle to half position then back to full. (On all other ESC's that I have during the programming you move the throttle to off. This will not work with these.) Moving the throttle to half position changes the mode form brake on to off. It is the second series of beeps.

Hello I don't understand... I try it but the motor turn on back ... Can you explain me All... For this trouble... I finish to the hospital. The propeller cut me...and i need 3 points...
 alexautom8s 212 points
Hey P51, Thanks, Yeah I down loaded the manual and was able to change/verify other settings but brake just doesn't seem to work.. It replies as setting took but it doesn't brake.. Curious if anyone has gotten brake to set on?

Possibly eol didn't supply correct voltage to esc or set xmt to full pwr prior to pwr up esc to get it in pgrm mode. Manual is under files tab. I had a low batt and esc got stuck in a loop until I supplied 5V.
 p51p51 44 points
Alex8 I noticed on some, the brake really doesn't "lock" like on some of the more expensive esc's. I do not use the brake function, but I do use the reverse feature which saves time.
Jeremy  25 points - 2/3/2011

I bought for my first plane (HK Bixler ARF) because it was in recomended parts for it, and I guess it's really wrong - it burned after only four flights, it gets really hot (even that plastic tube that covers it melted) and I think it's just to weak for that plane or maybe I have a bad luck and it was of poor quality

Good little ESC. Small and light due to no heatsink. Good quality silicone wire and a long pair of power leads. Programming was dead easy albeit, limited but this is a basic aircraft ESC that needs no fancy features. FANTASTIC linear throttle response and stays cool. The only negative is the receiver lead is rather short. 5 stars
