RE: ESC? Where's that GO?
I have done a lot of electrics including brushless like yours. Although mine are bigger than yours the set up is the same. (I fly .40- .60 sized electric planes.) Motor wires plugged into or soldered to ESC then esc plugged into (NOT SOLDERED) the battery pack. Manf. always want you to install switches and fuses but most electric flyers do not use them. (Especially fuses.) On brushed motors we usually solder esc to motor but on brushless like yours we use plugs on the esc to motor connection but heavy duty ones.(Gold Plated)
