I've been playing with my US 60/Saito 100 combo. Torque rolls are tough but possible. BUT, what I cant get it to do it flat spin. With the CG at 4.25 back (manual reccommends 4 1/8th) I try the usual: Straight up at full throttle, fulll right aileron, full right rudder. Once its spinning pretty good then reverse the ailerons and feed in down elevator for and upright spin. Thats supposed to be the drill, but the best I can get is and ugly downward spiral. No flat spin!

Anyone been able to coax a flat spin out of their US?

Thanks
Jim
