On the first flight I had the accelerometer sensitivity too high, but the roll sensitivity was fine.
In all hte following plots roll is red, and vertical acceleration is blue. Flown with a CTI L800 blue
So I changed the acceleration scale and removed the fins, leaving everything else unchanged...
(Slightly differnt motor CTI L820 Skidmark)
Then I re flew with the fins attached and the mechanical throw increased about 50%.
Again with a CTI L820 Skidmark.)
This flight almost looks like it worked, ad the roll was controlled during the early boost phase of the flight.
Either I have weird aerodynamics or I need a lot more control authority.
Its possible this last flight worked as designed until it got close to Mach 1 and saw shock wave issues.
The altimeter reported a maximum velocity of 1150 ft/sec or right near Mach 1.
Got to think about this one a bit more...
