Well Brett, I don't know what to tell ya. When I got this plane, the rudder was set to move a LOT. And for up control, the rudder went past 0 deg, and actually was set about 2 deg past 0 deg to push the airplane IN.
I had started by working with tip weight, removing itsty bits 1/16th ounce at a time over the last year, until the wing stopped dipping at hard turns up at 45 deg, and that's when I decided to start backing off the Rabe rudder. I removed ALL tip weight eventually ( a full 1/2 ounce) and the weight box is now totally empty.
The way it's set now, it's got about 3 deg offset at neutral, 7deg offset at max down control and about 5deg max offset at full up. It never goes past 0 deg anymore to push the plane in, it kicks out, neutral, then back out the way I have it set now, and it is SOOOO much better it isn't funny. Very little if any yaw in the corners anymore. It used to wag it's tail like a dog. It's so much cleaner now that the corners even appear sharper.
OH...BTW, I installed the motor at 0 offset right from the beginning, and most people look at it and think it has inset because Baron sanded the ply nose ring for offset, and with the motor at 0 deg it looks like inset until you measure the prop tips. I obviously have it setup very different from the last person who owned it.
This was a very early version of the Humbug that Baron was never happy with, and didn't retro fit the ST60 till much much later, and gave up on it yet again. Not sure what the level of understanding of trim was back then, but this thing was pretty out of whack )for me anyways) when I got it. Now, in all fairness to Baron, this thing passed through other hands before I got it, and someone else very likely messed with it, and made it worse.
For what it's worth, on the "run" of an FSR vs/ST60.... Well... you may be thinking of the typical west coast Tom Lay ST60 runs you probably see locally, and if that is what your comparing to the FSR run, yes, they are probably about the same or close for procession.
But, compared to the BigJim ST60 run, the ST60 runs you will find are two very different animals. The one ST60 run is with the stock high compression head, flatter pitch run, as even Pat Johnson recently reccomended the new APC13x4w as a good choice for ST60's, and that's probably why. The second type BigJim ST60 run is low compression hemi head, low RPM run. My ST56 is running a 13x6 in the mid 8K. Nothing at all like an FSR turning an 11x4 at 10500 or even a TL ST60 turning a 13x4 at 9800.
Mayhaps that is what you were thinking when comparing the FSR???
