Strange problem....

Curious...

Have you tried connecting the esc to the castlelink, then plugging the castlelink into the pc? Sometimes you have to play around with the order in which its all connected to get the castlelink programme to recognise the esc/ castle link etc.

Is the castlelink device getting hot at all when its connected to the esc?

If the motor isnt chiming when its connected to the esc & batts are plugged in & you then turn it on at the switch, its possible the BEC has died a silent death..

HH will probably tell you to deal directly with Castle- much quicker turn around time when getting the esc serviced or replaced etc, no middle men to mess around with.
