I need a manual for this please? I have a red blinking light on the ESC after little use. Batteries charged, had no problem before. Now the motor runs then cuts down to reduced revs with flashing light. Only running for about 5 seconds before cut back so not even hot. Using a 6 cell - 3000mv 20C LiPo with a Turningy 50-60.

Perhaps because the esc is only for maximal 4s lipos

On Sunday everything was ok. Today (tuesday) i check it with new tires and the motor work not fluetny, shakes a lot, has no power. I connect another motor and it works the same. Any ideas? ESC was surely not overloaded (worked with turnigy inrunner 3150kV on 2s, on slash 2wd).

Be aware - despite the manual that comes with this. and what ever else HK says you cannot program this esc in anyway. You can't program it by transmitter. You can't program it with a HK program card You can't program it with a HK usb link.

I change my last prognosis . I didn't wire the regulator right . The internal bec is weak. I have 3 fans running taxing the system . The regulator cured the 50% power thing l.

I added a voltage regulator and I can report the same problems

1 thumbs up!
this seems as good as the 150a esc that we all love .. it has 35v caps on so it could possibly do 6s if you keep the motor under 120a its exactly the same as the 150a in size even cables and quality ...i programmed it with my 150a card and that works just fine ,seems less juddery than 150a at low throttle ,excellent!!!...have added a video of me programming it with the card on youtube under teamblackcountry rc :)

All works well apart from it not having a very smooth start, it really does a "bang" everytime you start from a stop or low speed. Will have to wait till the programme card is available to see if the starting can be made better. Why werent the program cards available when these first came on the site?

Este variador é excelente pela relação preço qualidade, comprei-o e foi montado no Traxxas E-maxx a 4s, não tem qualquer sinal de aquecimento, e responde muito bem. Para mim não quero outro. Aconselho a todos.

Looked fairly solid out of the box, huge in size, but blew as soon as I connected a battery, top and bottom boards are connected by pins and one of the fets on the top board shorted out due to solder debris inside the case contacting the bottom circuit board and up she went!
