Hobbywing v2.1 problem
 

I'm having a problem with my HW 2.1 120amp, which appeared out of nowhere. Car was working fine one day, I pack up ... a couple of days later I go to the track and now it's doing this.

On the bench it doesn't have the power to make the slipper slip, unless I turn up the DRRS boost setting to 3. I had the DRRS on 1 before and never had a problem making it slip. On the track it runs well but it doesn't have the top speed it had before. It's like the turbo timing isn't kicking in.

So far I have:

replaced power cap and wires
tried different sensor wire
different motor
different receiver (with transponder and servo disconnected)
reflashed the firmware twice

Soooo .... I have no idea :confused:

Any thoughts?

Try resetting the throttle end points

What car are you running - if you have changed all of the above I'd look at your slipper and gears inside the transmission in case they are worn damaged (or if a dex210 the layshaft spacer worn as that's exactly what happened to me!)

Phew it's fixed. So apparently it was the sensor cable. Weird because I swapped the cable already. But somebody at the track unplugged the cable and plugged it back in. Presto. :thumbsup:
