I got to think on that a bit John. Airworthiness aside, then why am I not seeing some bad effects? I have no trouble trimming for level flight at full throttle. I guess perhaps a stronger spring on my trim control would do the same thing then as adding a trim tab? It appears that someone is writing an aeronautical law saying that 75hp does not require a trim tab, but 85hp does.
