RE: Beryll Flight Reports?
Rudder all you can get with 70% expo
Elevator - 12 degrees low rate w/ 29% expo/ 17 degrees high rate w/35% expo.
Knife Edge Mix - 6% for up elevator each way.
Ailerons High rate - 15 degrees up/ 13 degrees down ,50% expo
Ailerons Low rate - 12 degrees up/10 degrees down, 45% expo
I am using a JR system. I flip to high rate, all rates on one switch for snaps and spins. I have no throttle to elevator mix for down lines. You may want to start with 2% down elevator mix at low throttle for starters. I use 5 degrees up ailerons deflection for landing. I use no braking function on my Hacker C50 13XL. Prop of choice is the APC 20.5X14.
This is where I am at the moment after 120 plus flights.
