Hello, I am new to this sort of stuff and I am really interested in competing in Featherweight competitions in Robot Battling. The only issue with that is I don't know where to get the parts (I know that you can find the motor and battery in an 18v Drill) and how to put them together. I know that this is not where I should post this thread, but I do not know where. Please respond to where I can get the items.
