i have left my revo with the MMM sitting idle for 1 week. i recently rotated the mounting of the motor which required me to disconnect the wires from the esc. today i decided to charge up my Yeah racing 2s lipo for a quick spin. when i connected the battery to the esc i noticed a small spark from the connectors. hoping i hadn't inadvertently fried it i powered it on. it powered up with the first set of 4 tones but not the final set of tones, also the fan kept spinning faster and faster. the red and orange lights flashing on the esc were on but no response to radio input only the reverse mini servo initializing and thats it. i then decided to hook up the castle link to check the settings on the esc. the link hooked up well and then just did an update to ensure all settings were saved. i didnt make any changes but wanted to make sure they were saved anyway.after that, the esc was fine. i thought mine had bought the farm for sure but i hope its not a sign of things to come.
