Why........?
Has anyone installed better brakes on an RV-12? I know several guys who have upgraded brakes on RV-6 & 7's.
Have you checked with VANS? I know they are beefing up the iS version of the -12, to better accommodate flight schools. I wouldn't be surprised that beefier brakes are in the mix.
Also, how did the tower make you do a tailwind landing? I had that happen once in my Diamond and vowed to never accepted it again. Good Luck on the brake upgrade.
