Will this esc work with a 1/8 scale buggy with tekin 1900kv motor and 4s
 jeffrey 662 points
Yes it will work with that motor,but you see in in my review right below this question that the one I received last week does not work with the sensor hooked up,so word of caution if you are going to use it sensored it might or might work.Good luck you might get a good one,its probably a 50/50 chance you will get a good one,but what can you expect for $40 bucks.Get 2 if you can yourchances will be better.JK.
jeffrey  662 points - 5/9/2013
 
Hey guys,just letting you know that the one I received yesterday, works but not with the sensor hooked up.Has no acceleration and coggs very bad with the sensor hooked up.Works just fine with the sensor Unhooked.Just a Caution for you guys.JK.
 dandy 5 points
make sure your A-B-C wire connection are all correct.
 jeffrey 662 points
I have been in the hobby for over 30 years,its hooked up correctly.I have 4 of these that I have bought over the years.Was just letting everybody know that the new batch is not as good as older ones.JK.
 dbest325 59 points
I HAVE ONE FROM LAST YEAR THAT I AM RUNNING ON A TEKIN SENSORED MOTOR AND IT RUNS GREAT WITH TONS OF PUNCH ON THE BOTTOM, MAYBE YOU JUST GOT A DUD
 jeffrey 662 points
I am sure I did,going to order a few more and see what happens.JK.
Charles  1 points - 5/6/2013
 
Do u need the pro card to calibrate the throttle and if not how do u do it? I didn't order the card when I got the esc and i have been waiting a month to for the program card and can't use my cars cause they don't act right. Sometimes it goes forward when I pull the trigger and sometimes it doesn't or will randomly go in reverse!
 jeffrey 662 points
No you do not need the card to program the throttle.Turn your transmitter on,hook a battery up to the esc,While holding down the little red button on the on/off switch turn it on and hold it until the esc light comes on(about 4 seconds)pull the throttle to full throttle until the Orange LED is on solid,then release the red button,pull the throttle to full position until red LED blinks and will be on solid,the motor beeps.Then push the throttle to full brake position until the orange LED blinks and will be on solid,the motor beeps.Then return to neutral position,both the red LED and orande LED wink,the throttle range calibration is confirmed.You might have to change your throttle channel to reverse depending on your transmitter.Hope this helps.JK.

it seems to you might be recieving radio interference ? are you using a 2.4 ghz radio or an old crystal radio? hobbyking sells sone really nice 2.4ghz radios on here -brushless tends to create interferne itself-hope that helps
 Charles 1 points
i have the fsgt3b it is a 2.4 but i just needed to prog. the throttel. it is good now
Charles  1 points - 5/4/2013
 
does anyone know wha the little red button by the on off switch is for
 jeffrey 662 points
Yes,it is used to calibrate the throttle.Its in the directions.JK.
 dbest325 59 points
that is the "set" key it is used for a number of things. refer to your owners manual it will explain it all

Will this esc work with the track star 4x4 4.5t motor (550)
 THEnewBIE 6 points
Yes it will! This will provide plenty of power for your motor
 Justin 8 points
This ESC is slow from the start. Maybe its the programing maybe its the sensor all I know for sure is I put the castle back on.
 dbest325 59 points
that is too low of a kv motor for this esc hence the slow start it tells you not to use lower than 7.5 turn motors because of the rpm needed this is more of a 4 cell controller than a 3 cell it likes the low kv motors but you can gear them to the moon and back with low kv and there is no issue i have one running 42/63 in a 1700kv package and it screams
kerry  1 points - 4/22/2013
 
can this be but in losi 2.0 with tekin 1700kv motor
 kerry 1 points
Its the losi 8ight truggy 2.0
 dbest325 59 points
you need to run the numbers on the tekin motor but it should be fine
 bradley 2 points
the tekin 1700kv is a perfect match
Zach  1 points - 4/19/2013
 
You change the voltage cutoff with the programming card. It auto detects how many cells when you turn it on, and it beeps to indicate how many it detected. I found the default voltage cutoff was too low, and it was over-discharging my batteries. I believe it was 2.8V/cell. I changed it to 3.0V/cell and it seems to have solved the problem, though I would even consider ***ping it up to 3.2. If you're running NiMH or NiCd batteries, you can disable the voltage cutoff entirely.
 acb218 2 points
mine came stock at 3.0v/cell. thats also what it said in the instruction manual. I do agree that that is a little low though.
 adam 1 points
The answer is yes you can disable the cutoff entirely only on NiMH or NiCd. Run those cells down for a good charge next time.
Mike  1 points - 4/14/2013
 
I have a question about batteries. In the manual I can't find where it specifically says how to change battery types.... All I can find is low voltage cut-off. I know low voltage cut off is for lipos..... But I keep seeing peeps say to check settings to see if you have it set for lipos. Just Wanna make sure... Don't Wanna kill this beast of a awesome esc. I'm running a couple of 2s and 3s. What should cut off voltage should I set it at. THX for being patient.
 acb218 2 points
the esc will auto-detect the type of battery so you dont need to worry about lip vs. nimh. if you are running nimh though, make sure you turn off the lipo cut-off because it will prohibit your maximum runtime. you wont kill it with 2-3 cells though. that is a perfect sweet spot. I even run 4s 5000mAh 40C batteries and it barely gets hot.
Zach  1 points - 4/11/2013
 
This is effectively a SENSORLESS ESC. With the sensor cable connected, acceleration is smooth, but prohibitively slow for anything but crawling. Changing settings using the programming card does not solve the acceleration problem. That said, it is still a GOOD sensorless ESC, it just should not be considered as an alternative to other sensored ESCs.
 acb218 2 points
my acceleration is too much. i had to turn mine down to save my differentials. yours is probably defective. send it back in...
 dbest325 59 points
agreed with acb218 must be defective i had to turn the punch down to save my truck as well and im running a sensored motor
david  1 points - 4/4/2013
 
i have this esc on a 1/8 buggy doesnt seem to brake going into corners do i need the program card for this to happen
 mdkwarhawk 80 points
yes the program card will help you with many setting. the card is a must
 acb218 2 points
the brake on mine is very strong. are you saying you cant brake when you turn? that doesn't make sense. the programming card will help you out though. good luck!
 negus11 7 points
Do you mean drag brake?
Zach  1 points - 4/4/2013
 
Can this ESC be programmed without the programming card? Other similar ESCs allow you to change settings by following a series of beeps or flashes while holding down the "set" button.
 mdkwarhawk 80 points
no this esc cannot be programmed without the esc as i have been told i own three and also have not found a way
 acb218 2 points
you can only set the throttle calibration with the set button. you must have the HKSS 150a programming card in order to change any other settings.
rdg1035  1 points - 3/29/2013
 
Hello. I'm experiencing slow acceleration with this esc. Went through all the throttle calibration steps and everything checked out. When I use the esc and motor with the sensor cable attached acceleration is slow. When I remove the sensor cable, acceleration is good (aside from a little bit of cogging at low throttle). I've played with the settings using the programming card and none of them seem to help. Here's my current set-up: 1/10 2WD SCT 24t pinion 81t spur Turnigy nano-tech 5000mah 2S 35~70C Lipo Pack Hobby King 120A Sensored/Sensorless Car ESC Turnigy TrackStar 17.5T Sensored Brushless Motor 2270KV Any ideas? Thanks.
 mdkwarhawk 80 points
in my opinion the problem is with your battery i run this esc and ran it on a 2s 10000 mah battery it wants more power than a 2s you should really run 3s or 4s on this esc your starving it on anything less
Jimmie  1 points - 3/27/2013
 
Hi all, What card is compatible with this ESC? I have a hobby King hkss programming card, however it says "for the HK 150A Car ESC only". Heres a pic of the card Thanks, Jwalk33
 mdkwarhawk 80 points
that is the right card and the one im using
rdg1035  1 points - 3/26/2013
 
Kinda new. What does everyone use for their throttle limit setting?
 mdkwarhawk 80 points
nope i run savox in my 1/8 buggy with this esc just fine
 mdkwarhawk 80 points
i hope this answers your question *******youtu.be/f1O0QAELBRo
Brian  1 points - 3/22/2013
 
I plan on using this esc in a 1/8 buggy with the turnigy 1900kv just for bashing. You guys think ill have glitching trouble if I use a savox 1268 servo?
 mdkwarhawk 80 points
nope i run a savox with this esc in my duratrax buggy 1/8 just fine
chad  2 points - 3/19/2013
 
thanks adam but that didnt change anything i hope i didnt waste my money on this but i have went completly thru all steps and it only programs in reverse what to do ???????
 rdg1035 1 points
I had the same problem. When you're calibrating and the instructions say to hold the throttle at 100%, try holding it there for a little longer like 10-15 secs? Then go reverse.
adam  1 points - 3/18/2013
 
Try switching your motor wires around
chad  2 points - 3/16/2013
 
so i bought this to put in my tmaxx conversion and i cant get it to setup to go forward it wants to program for reverse any help using a turnigy trackstar 2650 motor and 5300 lipo battery help i want to go reaally fast whats the deal
jeff  3 points - 2/28/2013
 
I would say yes because i have run the castle 1/10 7700kv with noproblems.Ive run these on 1/8 - 1/10 and worked great on 2pole - 6pole. This is a great esc and is sensor/sensorless
Sean  1 points - 2/18/2013
 
Can I use this esc with a 3.5t 1/10th Trackstar motor for speed runs? If not what should I be looking for?
Cochabamba  1 points - 2/18/2013
 
How do you connect batteries set-up for an emaxx with this esc? Do you do a Series set-up or a parrallel set-up? Please advise.
guillermo  1 points - 2/18/2013
 
how can I program this esc with out the programing card ,I need help! does any body have on idea.
 ashanti j 24 points
it is programmable via set button but being you dont have a manual or any way of knowing what item u r in you should just get the card or refer to a manual of another esc that is similar with set button you can program with.
silvano  2 points - 2/17/2013
 
Where can I find the program card for the 120A esc
 ashanti j 24 points
you can use the hk150a program card or purchase a 120-150 amp esc seeking program card this way you can use it with most of your esc's
Sulaku  1 points - 2/15/2013
 
Yes it does, its also programmable if you want to change it.
montemadness  5 points - 2/13/2013
 
Does this esc have reverse. It doesn't say
 acb218 2 points
yes, this esc comes with reverse out of the box. it only works from a complete stop though.
hank74  68 points - 2/11/2013
 
how is it with a 10 turn motor like the Velineon 3500
 hybrid32494 34 points
its fine, i tried it myself. You can easily run 4s power with this esc and never overheat.

Can this run the castle 1410 3800kv 4-pole motor fine? Please reply! Cheers :)
 Dallas 1 points
Yes, I run a 3400kv tenshock 4pole that is much more powerful, just gear it right and youll be fine!
 hybrid32494 34 points
yes, i have ran more powerfull 8th scale motors and it was great.
 Aquito 28 points
Yes you can. I run this ESC on my Losi SCTE with a 1410 Castle 3800kv motor and it works excellent. I run it on my local track without a problem and it never over heats. I can seriously say its the best ESC I have had.

When will this likely be in stock here or in the international warehouse? Does anyone know approximately when it ran out of stock?
 John 2 points
I don't know. I ordered 2 from the international warehouse on 10/30/12, they just arrived today 11/17/2012. The 80 amp ones are still in stock, are you sure you need a 120 amp? If you run the 80 amp unit on 3S power (11.1v) you can run up to ~800 watts!
 Jason50153 8 points
Thanks for the info. I'm debating on just going with the 80 amp version. I would really prefer the 120 one though. So I'm just wondering if I should wait.
 John 2 points
If you can run 3S power, then you are fine with the 80amp, if you don't wish to wait on the 120amp version.
 hybrid32494 34 points
ive run both the 80A and the 120A on 4s and 6s lipos. they both perform very well, if not exactly the same. Keep in mind i ran 25C batteries, not the high powered 40C and over.

I put this in a regular rustler with a 6000kv motor. I know it is over kill, but this thing screams! with the built in fan. it never gets hot at all. I set this up with out the program card, but i may still get one to change the different settings. It has 12 ga wire and it also has a port for another fan for the motor or battery. This thing barley fit in the rustler, but it works great.
