Here is an outside view, from an airshow at Powell River, July 2014

Pitts performance detail.  With thanks to Bret Davenport, he ran his numbers for his modified S-1, but should be a close correlation to anyone flying a modified Pitts.  He’s also got the stock S-1 numbers there.

OK, so I'm back in Advanced after 22 years in Unlimited.  My 180 hp S-1 was begging me..."no more, master"

Skunked out - weather, cancelled contests, work, family






Apple Cup - Ephrata WA

Ugly weather going down, found a new (to me) jigsaw route low level through the Cascades.  Riding a rosy forecast I returned on top at 9000'.

North American Team Championships
Ephrata Washington

No use crying about it, I should have read the new rule book and figured out that 3x4 means a point roll. That zero in the unknown cost me 1st.  The winner did nail an 88% Free though, which deserves a win.

2nd Place Advanced


Bad year, my mind wasn't on it.

Tried to get across the Cascades but the weather skunked me out


Spilled the milk on the Known program - zeroed a figure, bumbled a roller and took an interruption.  Dead last.  Then did the Greek thing and came from behind, 2nd in the Free and won the Unknown.  I'm in the hunt!
Even ate a 50 point penalty for an illegal wingwag in the Unknown - where has the love gone?

Apple Cup, Ephrata WA
2nd in the Known, won the Free handily, was almost slapping myself on the back until I realized I had finished the Unknown flying in the wrong direction.

Apple Cup, Ephrata WA
Found out after the Known that I'd been practising it wrong since November, plus I got confused and zeroed the second last figure.  Dang.  Composed myself and knocked the Free and Unknown out of the park.
