Hi guys i have a Blade Cx2 the red wire has been pulled from the esc I know i could try to resolder the wire but the temps could fry the board. Ugh they made the other connections pins, this is why detroit killed the electric car to sell parts!

Since it's useless anyway you might as well try to resolder it. If it's new enough you could try to get warranty service.

Solder it with a fine point low wattage iron.
