Which size bullet conector should i use? Thanks karl!
 Karl 261 points
I use PolyMax 3.5mm Gold Connectors 10 PAIRS (20PC), PRODUCT ID: AM1001A. There rated for up to around 80 amps so you wont have any problems with them overheating. Let me know if you have anymore questions as I would be happy to help.

How do I test this esc? I plugged it in for the first time. It made 2 barely audible beeps. A couple seconds later 2 more, again barely audible. Then nothing.... Any ideas? Did I get a bad esc? Thanks

this would be the right ESC to replace the one on my bixler v1.1?
 Santhosh_r 267 points
Yes ..it is good replacement for Bixler 1.1
 Malcolm 83 points
While this ESC will work, I would opt for a slightly larger (25-30A ESC) just for safety and less strain on a smaller ESC (less chance of burning out)
Depending on your prop/ motor combo, the Bix can easily consume 18-20A, and leave you with no extra capacity to assist with heat dissipation.

Are these the same esc that supply with hk bixler, 1.1? If yes how to program it to use lipo. Thanks
 Santhosh_r 267 points
Yes..you can use this....you don't need to program it ...it automatically detects LiPo
Peter  2 points - 5/16/2013
 
Hi, I have a bixler 1 and the esc has stopped working.
would this be a suitable replacement? or any suggestions?
would buying a 30A be ok?
 Santhosh_r 267 points
better buy 30A ESC for safety..
 Karl 261 points
Its always better to have a higher rated esc than a lower, because the motor only draws as many amps as it needs. Buy the 30 amp.
 Steve 1 points
WELL, THE CHOICE IS >> DO YOU WANT TO BURN OUT THE ESC OR THE MOTOR IF PROP GETS HUNG UP? SIMILAR PRICE.
Anggara  5 points - 5/15/2013
 
I bought these esc and had never been able to use it for my quad. It was just stuttering so I bought other types which worked well. Now with all the flashing going on I tried to solder wire strand but the chip is just too small. Smaller than my other esc. Any idea what*s the best way to connect programmer?
 Santhosh_r 267 points
Did you see the IC adapter to flash SKU: 332000007
 Anggara 5 points
Yes I did. As I said before the chip on mine is smaller than other ESCs. Do you know what size is SKU: 332000007?
 Carly 29 points
If you have this ESC then 332000007 will work for you. I can confirm from personal experience
 Anggara 5 points
Hi Carly, can you measure your chip size? Mine is only 4 mm. My other ESC (hobbywing type) has 6 mm chip.
 Carly 29 points
I measured 8mm, or 1/4 inch for the chip. If you look at it in the correct lighting, it should say ATMEL on it. It it says ATMEL, you know you can use SKU: 332000007
BEST ANSWER CREDIT AWARDED
 Anggara 5 points
Thanks. It does say ATMEL 8L but sounds like a different MCU package than yours.
 Carly 29 points
Interesting, are you telling me your chip is actually 4mm? Sorry to assume ALL of these boards came only with the 8mm chip I have :-) Sounds like you bought these a while ago, I purchased mine around January 2013, so maybe you had a different batch. Thanks for the credit and best of luck!
 Anggara 5 points
That's correct, I bought it in 2011 and never got it to work. Motor just stutters and it's not card programmable either, hence the reason I want to flash it.
 Carly 29 points
If you got it that long ago, I really suggest you don't flash it. In the order I received this year, 3/4 were different than the 4th. The 4th seemed like an older revision of the board, or a different board completely. I flashed it with SimonK and the board fried after a few take offs. The other three are running strong.

Hoy do i calibrate the throtle range? I have them in a quad but they need to be calibrated
 DREYER 10 points
Do not know if it's true, try to start all the speed with throttle in the same position, this fixed the starting point of the speed.
 Karl 261 points
Power on tx and put throttle at full. Then power on the ESC and wait for when it goes beep,beep quickly. Then close throttle fully. You should hear a long beep. That's what I do with this in my plane. Hope it helps. If my beeps are off sorry as I don't have the ESC right next to me
 Carly 29 points
Depends on the firmware of the board, I'm using Hobby King's KK v2.1, reflashed with XXcopter. I have to turn my YAW pot to 0%. Then put throttle to 100%, power on KK board, wait for three LED flashes and put throttle to 0%, after second 3 LED flashes, power off board and restore YAW

This just arrived and I'm not impressed. How the hell am i supposed to connect the battery????? If I knew it didn't come with a battery connector I would not have bought it. Try more photos and info HK.
 H-KING_SCOTT 5236 points
If it came with a connector......it would have shown which one in the photo......since virtually NO speed controllers come with battery connectors fitted as standard.......as there are just too many connectors out there to choose from......you should not really have been suprised.
 flyingdrummer 13 points
I bought an identical one about 2 years ago which came with JST connector.... Just an extra hassle I hadn't planned on. No idea how to connect them but I guess I'll have to learn now!

Can anyone tell me, this ESC has 3 wires coming out marked a,b & c. I have a geared motor that only has 2 wires, how does this get connected, thanks.
 Karl 261 points
Check your motor specs because it sounds like you have a brushed motor. In that case you cannot use this ESC because it is a brushless one. Check the ESC tab on the website because I think that hobby king sells a brushed ESC as well ( it might even be a little cheaper too). Good luck and happy flying. If you have any more questions just let me know as I would be happy to help.

Yeah, geared motor configuration use brushed inrunners most of the time. Brushed motors have more torque , have more power at the start up than brushless.
MOREON  2 points - 3/24/2013
 
Does it comes with the bullet points connectors pre-installed ??
 Karl 261 points
NO it does not come with any connectors (battery or for the motor) I am using these connectors. PolyMax 3.5mm Gold Connectors 10 PAIRS (20PC) They are great. The male or bullet shaped part goes on the motor and the female goes onto this speed controller. Good luck.

Thanks for the info :) although I still think it is safer to go a couple Amps more in each "step" like I prefer to always have the ESC be able to handle more than what my motor can handle, and my battery to be able to handle more than what the ESC can Cheers, Twan
twan  16 points - 3/22/2013
 
25C 0.5Ah i think you mean (or 500mAh) is gives 0,5x25=12,5A of constant current, and you always need more current from the battery then your ESC can handle, so no, you could use a 10A ESC for this battery For this ESC, you need at least a 25A of constant current from your battery, so either a battery twice as big, or twice the C rating cheers Twan
 mena142 746 points
Just to enlighten you a little. The amp rating on ESCs only mean how much current the ESC can handle going though it without overheating, it doesn't mean how much power is going to be "pushed" into your motor, or drawn from your battery. What actually matters is your motor prop combination, given your battery voltage. You could use a 120a ESC with a 1C 2S 120mAh battery, as long as your motor spinning your prop from the battery voltage (thats what kv is for) is less than 120mAh. People generally go for a higher ESC to prevent overheating, but they use the same batteries. Good luck.

could use this esc 25c 0,5 mah lipo?
 Malcolm 83 points
You could, but will damage the battery as it is too small. Use either a larger battery such as 25c 1000mAh or smaller ESC like 10 Amp.
 mena142 746 points
It doesn't depend on your lipo capacity, it depend on how much amperage does your motor prop battery voltage combination. If your Lipo(2s or 3S) plus your motor and prop draw 18a or lower you can safely use this ESC. I've said this over and over, the ESC only supplies what the motor demands, same goes for the battery, they dont "PUSH" anything into the motor.

thank you mena142, 18a esc is the only about motor amp capacity, my brusless motor is using 9A i think it's means to i use this esc with my park300 and 25c 0,5 mah lipo, am i right?

 Bjarki 30 points
Try turning on your transmitter, put it on full throttel, turn on the plane and wait for the first beep sequence to be over. then close the throttel again. this should set the endpoints differently. i believe that could be the problem. good luck

I hope someone can help, I'm using a HK-SS20A controller with a 6634 motor on my Piaget with 800mAh 2cell battery, when I power up the ECS goes through its start up OK, but when I go past half way with the Throttle it cut out,waits a second then goes through the start beep sequence, half throttle is not enough to fly, if you do get up and accidently hit the throttle it cut out and usually crashes,any ideas

DIY fixer question: Could this be able to power a 12v 12amps 2.5HP treadmill dc motor ? If not, please tell me why. Thank-you.
 Audi_tt 83 7 points
its can't be used to power a DC motor because this esc like a lot of more modern ones are inverters so they give out a 3 phase AC signal
aaron  1 points - 1/27/2013
 
Does this esc have reverse ?
 Karl 261 points
No it does not. It is made for planes or mulitrotors mainly (thats what I use it for). If you are looking for a motor with reverse im guessing that you have either a car or boat. If so, hobbyking has some of those in the esc drawer. Good luck!
 Karl 261 points
I am sorry i meant if you are looking for an esc with reverse... not motor. Sorry
 Miravo 28 points
This ESC don't have any reverse function, without changing the wiring of the motor: If you just exchange 2 wires on the 3 ones to the motor, then it will reverse the rotation. But no way to reverse with the command.

Willa  12 points - 1/4/2013
 
Yes there is a linear BEC: The power output depends on the voltage you supply to the ESC. The higher the voltage, the lower is the power output of the BEC. With 3S (11.1V) you can most likely draw a continuous current of 1A.
Joshua  5 points - 1/4/2013
 
Is there a bec in this speed controller? If yes what is its power output

Yes, and it is explicit in the product description. The BEC output is 2A.

Anyone safely flashed these with simonk firmware for multirotor use??...safely i.e without causing them to burn out due to p-fet gate noise as stated on the simonk site....is the reset pin disabled???
 Spark29 12 points
i was wondering the same thing. Well, not for the multirotor purpose, but just for an overall better performance.

According to this site you can. I am going to order four ESC's and flash them. www.link

I have just done so today. I have the newer supposedly unflashable version and using a usbasp and the latest stable build of the lazyzero kk flash tool it went perfectly on all three and my tricopter is better than ever.

hi anyone knows if the esc was weak, what will happened? is the receiver also can not receipt the signal?
Nikolay  1 points - 11/26/2012
 
Can someone tell me please, how to use this ESC. I'm trying to control it with a PWM signal from an Arduino. What is the algorithm of usage? I know, how to send a PWM, but what value is needed to arm it?
 mena142 746 points
Can't tell you extacly how to setup the PWM signal as I don't know a thing about Arduino, but you should first programm the "throttle range". Throttle is Ch 3, just Go Full Throttle, power the ESC, it will beep, then go 0% Throttle, it should beep again. The ESC will arm when it's correctly plugged into a motor and receives a positive signal (and throttle is on 0%). This ESC will perceive a high refresh rate on the PWM as an error and shut down. 180Hz is too much. Hope this information helps!
 sashaNar 68 points
I have two of them, they just recalibrate the signal they get at power up as 0%. Normally you would use 1.5ms as zero throttle (min signal).

It really doesn't mean anything,it just allows you to know which wire is which in case you wish to change the rotation by switching any two wires.

Oh ok, so ummm, which is ground or the negative? Just wondering
 benybee 34 points
all A B C wire act the same.. it's just hi voltage signal, as the mater of brushless motor, the signal between them is switching each other to make the motor run.. if you wanna change the direction of the motor just swap between two cable.. that's it

*benybee, If I wanted to use on servo motors, will it work?
 mena142 746 points
The ESC alternates between two cables turning them positive and negative by turns, to create an alternating magnetic field that turn the motors. Servo motors are brushed motors, this is a brushless ESC so it won't work. If you really mean to, you can use a brushed ESC
 benybee 34 points

Very good controller, specially for this money.
With 16A it becomes a little bit warm, no problem.

One disadvantage: there is no manual included. (5 Stars with manual!)
So I have searched in web an i found that the controller is programmable.
Possible options:
- LIPO-mode (auto selection 2/3 cells)
- NIMH-mode
- Break on / off

To program this controller you have to move transmitter throttle to full position.
Now connect battery to controller.
Wait some seconds, than you hear:
*peep* - *short pause* - *peep*
*pause*
*peep*peep* - *short pause* -*peep*peep*
*pause*
*peep*peep*peep* - *short pause* -*peep*peep*peep*
*pause*
this sequence will repeat...

When you want to use NIHM cells, you have to move throttle to off position when you hear the first *beep*beep*. Than you have to wait for a longer *beeep* and a short *beep*. That's all. You can disconnect battery now.

When you want to select LIPO mode, start from the beginning (throttle full, connect battery, listen to the beeps)
At the time when you hear the first single *beep* move throttle to off and wait for
*beeep* and *beep*.

When you want to switch Brake On or Off, start from the beginning, then wait for the first *peep*peep*peep* within one sequence and put throttle to off. Wait for *beeep* and *beep*.

Note: When you connect battery and throttle is in off position you will hear a long *beeeep* when LIPO-mode ist selected or a short *beep* when NIMH-mode is active.

What can I say, this ESC is really simple and super easy to use.

I have attached to a test stand and can pull 17amps continuous (11.6V), the ESC cuts off at ~3.10V per cell. Does not heat up at 17amp draw. Near 20amp, the ESC gets warm, but nothing I would consider a problem.

Would highly recommend for those who want an ESC that is truly plug and play.

I would like to retract the statement that this unit does not work with 2.4 GHZ. I found that it actually does work but when you first plug in the controller to the receiver and add power you get a constant signal and the motor starts beeping. It is saying that the throttle is reversed. Set the throttle to reverse setting in radio...let it start in wrong position...then reverse it again to normal...unplug the receiver plug it back in..plug in the ESC to the battery and turn on the radio...The throttle will now start in the normal position and work like its supposed to.

Actually it works really well for this unit......its Great!!!

Purchased 2 of these both arrived within 6 days and work ok. 4 stars because ESC output not color codedand there are no instructions.
To arm :-Turn on receiver set throttle and trim to full power connect battery to ESC after first BEEP close throttle and trim ESC is armed.
Color code:-Lay the ESC down with the red (plusve)input wire at the closest to you the the outputs are Yellow closest to you then the red(plusve) and then the Black (_ve)wire.
