plugged in pack and motor spinned up, not turned on
This will happen if the pack is plugged in backwords, +->- and -->+. You are in a sense overloading then bypassing the speedo and giving power to the motor. I have seen this happen a few times with nimh batteries. There is no smoke and the motor spins up. In a novak esc, it can stand the condition for about 1-2 seconds, then the speedo is toast. It is very easy to hook the wires up backwords in a 3200 lipo pack, so please be very careful and always double check.
