Just wondering if anyone else had same - I returned a fully working V1 ESC for replacement and got back a "refurbished" one in return that smells a bit charred.
If you ever have a refurbished or repaired controller come back and fails, please contact Tech Support. We will get a replacement controller (new) out to you immediately, it will be sent with a prepaid mailer. Our new repair process allows for a quicker turn around, but does use a few more refurbished units. The smell is probably from it sitting next to a smelly, charred controller. Burned PCB odor lingers and gets into everything. There's nothing like opening a package and finding a bag of stinky black ash that spills on your desk and lap. If you do have any problems, please let us know and we'll get you fixed up.
I do agree with Neil(if it's not broke) but with V1's the wires are all over the place and the fan runs all the time making you think your running hotter than you are. It gets old after running a nice V3.
