Minn, I just saw a smoke valve & tubing by Dubro with a little arm on the valve that just requires an extra servo to activate it. This thing says it works off the pressure nipple on the backplate of the crankcase, with no pump needed. The price for this thing was $9.99 at the LHS.

I'm a firm believer that you pretty much get what you pay for! Is this thing gonna be $10 worth of headache & junk? Or do you think it might actually work?[&:]
