I am having a hard time keeping a good esc on my Slash. I am just wondering if I am doing anything wrong? I have been through four of them with three different motor combos. First the original vxl3 started smoking, then a mamba max pro started having major cogging issues, then a duratrax (castle) stopped giving power to the motor, then a brand new mamba max pro doesn't even turn on after its first run today. The switch is okay and it is getting power. I mount my esc's straight to my aluminum chassis via servo tape. Do you guys think the vibrations are shocking the esc. I have a mamba max pro on my losi with no issues, but it is mounted on plastic.
