Hey guys, wiring up some new gear in my 12th scale, and im finally (Attempting) to put a switch on my booster. My Question is, were do i put the switch, to the booster? I am using the small Hobbycity? booster. I tried directly to the speedy (Tekin RS-PRO). That didnt work. Can someone tell me were i have to solder it up to on the booster? Very confused haha

Thanks Antoni
