I had 90hrs total when I first flew my -3, most of that in 172 and 152's. However, I also had 15hrs in a 7AC Champ, and four hours in RV4's (thanks to my RV4 pals in Arlington WA
. The -3 is much easier to fly than the Champ, I never had trouble with either (the Champ heel brakes are annoying). The tailwheel springs MUST be rigged correctly on a -3 to get the docile ground handling - I use hw store extension springs that are slightly loose when just sitting there, tight when airborne.
850 RV3 hours
