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!
