FMS F3A Olympus 1400mm (55") Wingspan - PNP

[Habanero]

So my FMS F3A Olympus does a death spiral each time I add rudder input. I have my throws setup according to the book. The throws do look pretty extreme. Do I still have too much rudder? Any input beyond the slightest rudder turns the plane over, and I need to compensate with opposite aileron to keep the plane controllable. Other than that, it is a joy to fly. Maybe do one mode with very minimal rudder, then another one to pull off slow maneuvers like hammerheads?

Just a follow up on my own question. I took the FMS Olympus out yesterday and adjusted my dual rates from 75 down to 30 on the rudder. I put it in the air, and the rudder stability was much improved. At max throw, the plane barely showed the slightest tendency to dip a wing. Landed it and turned it down to 27 and that appears to be spot on. The aircraft now responds well to rudder put, and I can still get it to hammerhead at this setting. It no longer death spirals in coordinated turns. This is now my mid rates setting. I still have a higher high rate setting, but that seems to be entirely unnecessary. On my mid rates it responds like a very aerobatic airplane. On my low rates settings, it responds much more like a pattern plane. I put 2 more batteries through it just because of how much fun it is to fly now that I have my dual rates and expo adjusted better for this model. What a fun plane!
