Well he's right, though. Doing stupid things is one thing - advertising them is another.

When I saw the thread title, I started a big batch of popcorn before I even opened the thread.

Aircraft capability and safety notwithstanding, I note that my insurance does not cover any flight that exceeds the Operating Limitations on my Airworthiness Certificate. Which excludes aerobatics on my RV-9A.

This is incorrect. The 9 wing is thicker and the spar is taller then the -7. The -9 fuselage has a different center section than the -7 to accommodate the different wing spar.

I am now "confused, unsettled and very, very scared." Thanks for the laugh Josh!

Skylit
I thought they where the same thickness. I used blocks from a 7to space my centre section during the build and I did not notice any height difference. If the 9 is higher it only reinforces the extra torque math

today was broken clouds in Cincy around 3PM and only 500 ft thick. cruising underneath at 2900 ft and 140 kts I saw a hole and pulled up. I glanced at my rate of climb, 3500 ft/min, and about that time I was above the clouds and climbing rapidly at a nice angle. visions from Top Gun flooded my brain. not aerobatic, but Wow! I ascended to a different world of beauty.

I collected some engine temp data for OAT = 1C with 1 inch wide cowl inlet air dams installed. CHTS were within 10F of each other and my oil temp was 174F. CHT average = 320F at 4.5K ft. EGT as always, 1300F, at this low altitude.
