The patch for the FITU (Fixed Wing Instructor Training Unit), T-34C's at Whiting, has a T-34 in a spin with the OCF procedures around it. It is certainly an appropriate patch. As an IP or IP under training, we do spin after spin. With students in their FAM/contact stage, we do spin after spin. I've never done so many and I agree, a great way to build confidence for the student and for the IP. I've probably got close to 100 (studet spins included) in the last 8 months or so. I do more FAM and aerobatics than anything so spins, loops, barrel rolls, etc are on the menu daily.
