Say Randy, what engine were you using with your Warp Drive when you went
cruising along the ravine and what was the density altitude? At sea level
with my prop set to a fine pitch (say 12 degrees at the tip) I can easily
achieve 1100fpm climb at 75 knots (best rate). Different matter at high
DAlt. of course.
Sorry Don, I cannot answer your question about the impact on aerodynamics of
a 5" raised thrust line. All I know is the basics about the couple between
the four forces resulting in a pitch down at the stall. I guess you would
want to preserve that characteristic and so I suspect you might need to
lower the mount. Great Plains should be able to provide advice as I'm sure
they've dealt with a lot of KRs over the years since they developed the VW
derivative.
