Speed Passion Cirtix stock ESC, any opinions?

[kennedylanduk]

I've just bought a used buggy, and it came with a Speed Passion Cirtix stock ESC.

Any opinions on these? From what I gather online, they seem like a reasonable ESC as long as you have the program card to adjust the brakes (I don't have the card).

I have a speed passion program card Tony that I use for my reventon pro esc, might be the same as what u need?? If it is u are welcome to use it

I don't think they work on the model I have (I've been searching).

Will you have it tomorrow? If yes, I'll bring the ESC along to give it a go as there is a reventon card on ebay for £4 at the moment.
