Hobbyking SS Series 35-40A ESC

Yes.. This ESC will work fine with that motor.. I would suggest you use a prop that keeps your numbers below the maximum values though. Start with the recommended prop sizes (7x4 on 2S, or 5x5 on 3S) and see what they do on a watt meter.

Thanks for credit.

Hi Oreste, it is always safe to turn-off your model first, then the tx last. The motor running when your tx was turned-off might be a fail-safe setting. What tx/rx are you using?

 Heush23 3 points

Hi Oreste, Just think you must not, never, never turn-off your model before your radio. It's dangerous for you and the others. You must turn-on your radio before your model. And it will all good.

-but I love this controller! I really like the 3A BEC, and I'm driving my motor at 60% max! Very happy with this purchase!

 Roger 2722 points

The note says Do not use with motors of 3S or greater with a Kv of more than 2000rpm/v. Doing so will overload the ESC. It is not recommended to go against that.

 Roger 2722 points

its -100 to stop. 0 would be midway (center).

 Roger 2722 points

If you know the motor/prop combo will exceed the limit, why risk it? Choose an ESC that is at least 10-20% higher rated than motor's max current handling.

 (Mike) 564 points

the esc support less than 2000rpm/v, amps will be less than 27 tough

Verifique se todas as conexõ*es estã*o certas, em caso positivo inverta os cabos do esc no motor, ligue primeiro o radio depois conecte o cabo da bateria. Se ainda assim nã*o conseguir observe os botõ*es na parte inferior direita do rá*dio (HK t4a)para inverter os comandos e tente novamente.

I'm sorry, but I don't understand a word you wrote.

 neilton 2 points

tive a mesma dificuldade e quando inverti os comandos solucionei meu problema.

 JeffJC 3 points

Thank you for trying, but can somebody type in English. Thanks

 (Mike) 564 points

try plugging into a different port on rx, usually the port labeled on the rx but this is the most common reason of the beeps, if you hook up a servo it should still work to verify whether the bec(not esc) is faulty or small mistake.

 Roger 2722 points

Seems like a defective connection from esc to motor. That happens when one of the wire is not connected properly.

 Bruce 2 points

Thank you Roger, that was the problem. After checking my soldered connections with no success, I finally uncovered the connections on the ESC and re-soldered them - problem solved.

this esc can only work with motor of max 2000kv.It is not high KV ESC

 Dražen 7 points

max kv for this esc is 2000kv

 Snare_TS 66 points

Depending on what KV the motor you choose, the answer would be yes. If you selected the 1200Kv of the 2836, you can run 3s battery and be well under the max A if you prop it between a 9x5 and 10x6

 Snare_TS 66 points

Sounds like there is something stuck in the magnets of the motor. I would remove the casing and check for metallic shards. If there is something impeding the motor it could cause an over amperage situation leading to your ESC to burn up. What battery voltage were you using? What motor? Did this happen after you started to run it or just by plugging it in?

 Snare_TS 66 points

One wire (middle coming out of ESC) is power to motor. You cannot switch this wire to change rotation direction. You must switch outer wires to change motor directions. Also, you can change direction electronically via the ESC beep menu by following the instruction guide located in the attachments on this page.

 Roger 2722 points

Can be used with the DT1000 just fine.

 Roger 2722 points

More than enough for the DT750.

I already uploaded in file tab. this hex file is the one I flashed. I using kk flashing tools and choose atmega 8 based boot loader. may be u have you own.

 Hans 2 points

After receiving the "Atmel Atmega Socket Firmware Flashing Tool" (great tool!) I flashed this ESC with the rb50a.hex file (as advised by Nyana) , but afterward the ESC did …* nothing! No beeps, no moves from the engine, nothing! Then I flashed again using the rct50a.hex: nothing! Next, I sacrificed one more ESC, thinking the first one went broke during the process, this time in opposite order, but still nothing on both hex-files! Desperately googling for a solution I stumbled across a hex-file named HK-SS40.hex (in the rcgroups forum). I flashed, I prayed (not really...) and …* it worked! Since this hex-file was created (by a user named yovio) and based on an older SimonK-source, I would still be interested to find out which current version of SimonK's firmware supports this ESC. Any suggestions?

 Nyana 88 points

For my ESC , I am very sure it's working fine with rb50a.hex , also I uploaded on the file tab. So? I am not sure how you flashed? or loosing contact point I do not know. sometime it cannot flashed due to loose contact, but after I tried few more time it can flashed. I using KK flashing tools.

 Nyana 88 points

it can work well with rb50a.hex , I am very sure about this. I flash with IC presser tools. very simple , usiing with KK flashing tools, choose atmega 8base bootloader and flash it.

 Hans 2 points

Thanks Nyana, But did you flash exactly this very version (the one I took a picture of) and flew it? I did read the discussion below, regarding whether to use rb50a.hex or rct50a.hex, and I'm actually a bit confused since the RapidESC-Database entry also says rct50a.hex, although linked to a picture of what is obviously another version of this ESC.

 Nyana 88 points

No! that guy say rct50a but it doesn't work and not even spin. I flashed rb50a and fly hexa with ys-x6 before, then I change DJI and fly also. now I using on quad. no problem. very very nice.

 Nyana 88 points

Thanks for give me my first credit that I ever had, first I didn't believe we got credit. Now not bad, I will help you as know as I can. You want to see some video clips, you may see on youtube serch this one 20gmVkw8s2k. that one I using these esc flashed with rb50a.

 Hans 2 points

You're welcome Nyana, I just want to be sure it's EXACTLY this very version (the one I took a picture of) that you flashed.

 laz2336 1 points

i had issues running a NTM propdrive 2826 with this esc (stalled at about half throttle)so tried flashing it with simonk firmware. mine was identical to the pics Hans uploaded. using rct50a.hex and rb50a.hex it was completely dead. after tracking down a copy of hk-ss40a.hex and flashing that got it working nicely

 Hans 2 points

Hello laz2336. I was wondering where you found that copy of the hk-ss40a.hex file. The file that I found on rcgroups (as descibed a few postings above here) doesn't have the "a" in the name. I would be interested finding a file, based on a more recent version of SimonK's firmware.

 laz2336 1 points

If it lets me get away with posting it then this i sthe file i flashed with target=_blank>HK-SS40A.zip I had to google for it as a zip file to find it and it turned up here www.link

 Nyana 88 points

Oh really? I will try it out and get back soon. Because I've crash my hexacopter before. After that crash, I never try to fly again, may be due to I flashed rb50a, but it working fine for so many flight. Now I will flash this HK-SS40A

 laz2336 1 points

hk-ss40a was what it took to get any life out of my esc, the other 2 firmwares left it totally unresponsive. i think there must be a few revisions of this speed controller, if yours was flying with one of the other firmwares then i suspect it will be unresponsive with this one. but if you do try i'll be very interested to hear if it does work

 Poscis 53 points

probably a little warm but it shouldn't get too hot :)

 firedawg 59 points

No problem for that motor, alittle over kill but definately safe. Thats the way I do it, I never run close to the limit of the esc and have yet to have a failure. That motors only pulls 22a, so you may see 24a with throttle bursts. Try not to prop it at 22a or it won't last long, or be really careful with extended full throttle. Cheers

 firedawg 59 points

No problem with that battery, that esc is set to handle 3s, it will depend on your motor and prop from here. That battery will safely put out 36a (1.8 x20c), what motor are you using??

 MAURICIO 1 points

Friend FIREDAWG, can use this motor with ESC Turnigy D2836 / 8 1100KV Outrunner Brushless Motor www.link BATTERY Turnigy 2200mAh 3S 30C Lipo Pack! Thanks..

 firedawg 59 points

Mauricio. This esc would be fine. That motor only pulls 18a, so you would be very safe if you used a 3s battery and propped is correctly. 18a and 335watts on 4s. What type of plane are you planning on building with that motor??

 MAURICIO 1 points

I made a TRAINER CESAR EPO, 1.10 ASA ...

 max93 6 points

Can you further explain where you got that file and if flashing eventually permits to use >200kV motors? Thanks!

 Nyana 88 points

Go to www.link , and you have to buy "Atmel Atmega Socket Firmware Flashing Tool www.link and www.link

Wrong. Correct flash file is rct50a.hex (not rb50a.hex - there's no revisions of this ESC with all-N-FET's).

 Nyana 88 points

Ohh really? thanks, but now I flying with this firmware, no problem. Not objection, just I don't really understand about these flash files. Anyway, thanks I will flash this rct50a.hex and try it.

 ABLomas 38 points

You can't be flying with this firmware, as this requires completely different hardware layout (check 40A ESC's), so you mixed them or aren't flying. Photos of this ESC "naked" *RCG: showpost.php?p=23596499&postcount=6701

 Nyana 88 points

Thanks , I will re-flesh again for my hexacopter.

 Nyana 88 points

Dear ABLomas, are you very sure? rct50a.hex is correct firmware? have to tested? have you fly it before? It's totally cannot work with this file. Last time I flashed with rb50a.hex and I fly so many flight no problem. now rct50a even cannot spin motor. sound "dat-dat-dat-dat" at motor. I am not theory guy , I am practice man.

 Nyana 88 points

First I do not want to argue a lot, because I am not expert for this flashing ESC. When I post the first comment, I already flew my hexacopter with this ESC(flashed with rb50a.hex) .That's why I posted it(Take note that it can be flash with rb50a.hex and nice to use for Multicopter platform, nice throttle response.Great! I love it. Cheap Cheap).

 ABLomas 38 points

Yes, i'm sure about firmware. But there may be different firmware revisions - google github sim- identifying and read article about identifying PINs - maybe you got different revision and should apply another version.

You need choose motor with less than 2000kv.

 firedawg 59 points

if its the first 3 beeps you hear, then all the esc was telling you is that it recognizes a 3 cell battery was detected, and it probally set your throttle range when you dropped the stick.

 firedawg 59 points

I am quite sure you will be fine, I run a 30 amp turnigy on my bixler only cause I run turnigy on all my planes, stick with what doesn't fail ya, lol. Running 3s 4000 mah with a 6x4 and 6x5 apc, no heat issues
