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.
My trasnsmitter has a "throttle" range of -100 to 100. Does the transmitter need to be set at "0" for the ESC to stop, or "-100"? I've not received the ESC yet, and I dunno. (yeah, I'm a noob) I just don't want to hook it up and have my new motor and ESC running at full REVERSE when I first turn it on. My transmitter has all this programmable, but I've never used R/C before.
I have 4 of these, hooked them all up and all they do is beep continuously. They're giving no power to my receiver. I can't program because there's no connection. What am I doing wrong or are they just ****. Thanks
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.
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.
I have installed two of these ESCs with two NTM Series 35-30 1100kv / 380W motors . I have only one BEC to the receiver - the other is isolated. My problem is that only one motor will run up to full revs. The other motor kicks as if to start bu then just oscillates back and forth. What is wrong? I appreciate an help, thanks.
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?
I am not getting the dirction of rotation right. In one set of connection the direction is reversed. When I swap any of the two wires between ESC & motor there is no motion and the motor as well as ESC gets etremely heated up.........please help asap
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.
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.
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.
Did anyone of you flashed this ESC with SIMONK Firmware? Flashing should be possible, but the ESC that I just received from HK differs a littlebit from the HK-SS40A on the RapidESC database. To show you, I removed the heatshrink from one of them and posted two pictures under the Files tab. (HK-SS40A-Front and HK-SS40A-Back)
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.
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.
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
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.
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
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
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
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??
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
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.
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).
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.
I guess I am an idiot to misunderstand the manual and have barely figured out that I can switch between option 1 OR 2. But I can*t seem to get the brake to turn on and off. I drop the TX when 3 beeps , but the brake stays off always. Help?
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
5 thumbs up!
Lo he puesto en el HK 450 y no vale corta el variador.

Bought 3 of these. Installed in EZGlider Electric with KD 1050 kV motor on 3S 2250 Rhino LiPo. Very erratic throttle response and even no throttle response. Repalced with a second - seems to be running OK now. Have not checked temps.

Be careful. Mine locks up under 20Aplus current. Do a good ground test before put it to the air.

muy buen precio... buen rendimiento... para un motor de 25A lo estoy usando.
