Minn,
That made me sooo droll.
That video gave me the resolve to take a off work next week and build 8 hours a day for 7 days. Now I have to use a smoke system! Thinking back, my friend did have some large gaps on his control surfaces. After seeing your video, you are the best person to answer a few questions that I have:
1. How did you set up that smoke system? This is my first attempt, so spare no detail (i.e. tank size, running tank line, part numbers and pics would be great).
2. On the ailerons, point well taken. What is the best way to seal control surface gaps?
Equation for perfect showplane: (smoke system + skybolt video) * inverted flatspin = I'm calling in sick for a few days.
