I'm Jim McElvain, the owner of N711DQ, a 1974 KCAB. I've got a tailwheel wearing unevenly and little paint that has cracked. I'll get in the forums and questions and see what I can find.
I'll post a pic soon. The only acro I'm doing is loops, spins and wing overs. It's a wood wing and spades are not approved. My poor, old shoulders just cannot input the pressure required for a roll.
