2MM Cobra? That is VERY little...
I probably have an inch up and down on Elev. and 3/4 on AIl.
The elevator chord is one inch, as is the aileron. I assume you mean total throw, as in 1/2 inch up and 1/2 inch down, i.e. 12.5mm on the elevator? That's 26-27 degrees deflection. Otherwise you'd be the first person I've heard of flying 3D with a Magnum! It still seems like a lot though. I like mine much better once I dialed down the throws all around, saving the large elevator throw until the end of the stick's travel for flare.
It would not surprise me at all that at speed 2mm is more than enough for a decent roll rate.
