The Harmon link works for me ?? Both “rockets” are RV 4/8 with a larger engine. The F-1 also has a modified (tapered) wing, which makes it better looking, not sure about better performance. They are light airplanes with large engines, just like the -4/8, only slightly heavier and much more power. I don’t see what should be off with the Vs. The original stall speed of the -4 is 48, while the -8 is 51.
The links work here too.
This is what I get…
@RobertL18C I decline any responsibility
