Brushless ESC's

[cheesyd]

I have a Losi Xcelorin S ESC that i think has just died. It powers up however the power is no longer delivered smooth. I have reset to Profile #2 Modified and reset up to my transmitter but still have the problem. Does anyone have any ideas?

If it is kaput then I need to buy a new or used replacement. Can anyone suggest any quality ESC's? Im a serious racer and want to keep up with the best and was thinking about Tekin RS Pro however nearly £200 is a bit above my budget. I know thats probably a contradiction but we all have a budget unless sponsored and I need other things. I dont mind paying £120 for second hand but what if it breaks??? repair costs?

Please give me your thoughts and experiences as in dilemma which is stopping me race :-(

Get a speed passion revention pro 109 shipped with a motor or a hobbywing V2.1 80 from the UK there are lots of cheapish escs out there now that are really good

Might sound daft,but have you checked your sensor wire to motor for breaks/loose connections etc?
