Hi all,
I figured that this forum would be the best place to ask this:

How would I go about being able to control a brushless motor with only its 100% on/off function without using a wireless reciever? Is there a way to connect the ESC directly to a switch that would turn it on and off? Would there be a special type of ESC for this?

I saw in a video of a guy controlling a brushless motor with only a dial, but I can't seem to find that video again. Perhaps one of you knows what device I am talking about?

Thank you so much!
