hi guys, i am new to this robot building lark and i have got a few problems, i bought 2 of these speed controllers a while back, unfortunatley i have lost the instructions as to which color wires go where, i have also noticed that on one of the leads that i think goes to the tx, there are 3 wires and only one of them is connected to the little plug, the other 2 wires are not, is this normal, my other problem is how to fire the ram, do i just wire the solenoids to the tx or is there another way of doing it, any help would be great thanks guys
