So online I keep finding these cheap speed controllers but I just want to find one either attached to a motor or can plug into a simple motor that isn't to expensive I just wanna make a little rc car type thing for fun to learn more on motors and Arduino using wireless

note: I might not look at this post often do to bit busy but i will try to remember to check for responses

Search "electronoob esc" for lengthy, D.I.Y. ESCs.
