Just an update!
The Thundervolt P met its demise Sunday at the Pewaukee contest. It was a bit windy and on the second flight in the Overhead Eight, the wind shifted nearly 90 degrees and came off the tree line that was close to the circle. This cause a lot of turbulence at the top of the circle and the next thing I knew, I'm looking at the top of the airplane with the nose pointing slightly down and zero line tension. It was over a second or 2 later.
I was using my $25 Zippy Compact 5S 2450 35C batteries and this one got damaged. Sure beats killing a $100 battery! The Cobra 2826/12 survived with a shaft and bearing change. I salvaged the stab, elevators, flaps, and landing gear to be used on the next one.
It was a very good flying airplane that presented very well.
