Is there a kit you can purchase and install to be controlled by a channel and smoke at any given intervals?

Yep, quite a few. Do a search for smoke. They do require a fairly large motor to work effectively. There are also smoke systems that use "smoke bombs", but it's a one shot deal. You will run across these as well in your search results.

TME Smoke are very good, but you do need a large engine to make it work well. They also make mufflers with preheaters to make the oil burn more effectivley.
