Excellent idea. I just wonder how you would turn the smoke one and off as this would supply pressure as soon as the engine is cranked? Do you put a servo actuated valve in the line like you do in using an electric smoke pump? If you do, what effect would that have on the Perry Pump with it pumping against a closed exhaust port?

I too would like to have some feedback on this as I would love to put smoke in my new Yak 54, and in the Goldberg Ultimate I will be picking up soon using the gift card Christmas present from my sons and their families.
