RE: Pipe Thru the Canopy Phoenix
I like it. I want to do a Vertigo that way. The canopy is large enough to completely enclose the pipe.
My old Vertigo's had distinctly different knife-edge characteristics from one side to the other. I theorized that the airflow disturbance from the engine cut-out as well as the exposed engine disrupting the airflow along the fuselage side was responsible. (And I'm sticking to it) I would be willing to bet that an upright or inverted installation would help that out a bit.
