I guess it is in my hobbyist nature. Haven't you EVER put modifications on a plane? Carbon, glass, change dihedral? Adjust incidence? Or even scratch built? Just to see what happens? If you take a risk in mods to improve performance, doesn't it feel GOOD when it works?
Some guys like the hobby to relax, some like to build, others just fly. I like to experiment. The Coyote is a cool plane, I have one now flying, and another in the box on the shelf for a later time.
The guy that designed it, probably flew and experimented on it plenty.
And I'm sure he wrote the directions. The directions state: "...if you have great lift regularly, clip off 6" from each tip and watch it become even more impressive."
So has anyone done this?
