Looks nice but does not seem like anything out of the ordinary???? Seems like most of those mods are STC'd anyway.
"A stock PA-12 topped out at 115
mph, cruised at 105, and climbed at a
sedate 650 fpm. According to its GPS,
397JH cruises at 135 to 140 mph, and
lightly loaded (pilot and half fuel)
has an initial rate of climb around
2,000 fpm. It gets off short, Tom says,
and lands slowly, which has always
been two of the Super Cruiser’s most
admired traits."
135mph? HUH??
