leopard speed controller
 

i recently purchased a revo brushless conversion from kershaw designs and its been less than amonth and the esc is acting foolish. its a leopard esc and motor for 8th scale. just in the last few days the esc acts like it is losing signal and running away. i have put 4 different receivers and radio combos and it does the same, thats why i say esc not rx/tx. i have an email in to kershaw but havent heard back yet but was wondering if anyone has any experience with this issue? any help is greatly appreciated.

Sounds the same as my kids....except they lose focus, not signal.
