On another note. There's a reason the measure twice cut once ruled come out. Just soldered up three speed controls in a hurry and managed to Solder the battery wires backwards on one of the Tekin RS. No smoke but boy did she get hot. Did not pop the cap either. So I am wondering if the is cap is bad. Anyway resoldered it correctly and it seems to work fine? Seems kind of strange to me but not complaining.
