I did a search of StuntHangar and a web search to see if anyone sells the plans to Paul Walker's Impact.
What I'm really interested in is seeing how he does the take-apart tail. I have read Paul's trim chart articles in Stunt News and listened to his discussion of the trim chart on StuntHangar Video Hangout, and it seems that in addition to adjustable tip weight, adjustable leadouts, and such, we should probably also have adjustable stabilizer incidence as a trimming tool.
Perhaps there are magazine articles or a Stunt News issues that show how people have engineered take-apart tails that would lend themselves to adjustable stabilizer incidence.
Thanks,
Joe Ed Pederson
