Check out the Slimline Products website. I don't have the web address, but it should be a snap for
your search engine to find. Additionally, they are an RCU advertiser so they should be quite easy for
you to find.

They offer a simple smoke system that is said to work quite well for 2C engines. I haven't actually used one,
but I think they have a video on the site that shows the system in action.

Check it out!
