Oops Tailslide - VNE Dive, Wind Up Turns, and Aerobatics - last flight of JellybeanThorp program

The tailslide was unintentional. The goal for that maneuver had been to demonstrate the minimum entry speed for a loop and included a build-up to that maneuver (13:41 in the video). When the airplane stalled on the upline I knew I was in trouble, the plan had been to use a hammerhead to recover...it sort of worked. Important note: a T-18 has no uplock on the flaps, so if the airplane goes to negative G there is the risk that the flaps will deploy uncommanded and damage the airplane.

This the last flight of the JellyBeanThorp program included a dive to VNE (never exceed speed or redline), a wind-up turn to the published maximum G for this weight, and finally a minimum entry speed exploration for loops and rolls.

Likely the highest risk flight of the program it was also tons of fun. Super stoked to have been able to fly this famous Thorp, let alone take it to the corners. It's always a bit bittersweet when a program wraps up and you have to give the airplane back to the owner...and I can admit this one hurt more than most.

A big thank you to our sponsor Butler Parachute (https://www.butlerparachutes.com/). My HX-400, highspeed opening, emergency parachute gives me the confidence I need to do this kind of high-risk flight test. Butler is the best in the business and we appreciate their support.
