This is one of the speed controllers that I bought

 and  was never actually used. It is in like new condition

 except I did solder on the EC5 connector & 3 bullet

 connectors for the motor (which I removed) and that is

 why I am selling it as used.. I paid $218.48 from AMain

 Hobbies. My loss is your gain.
