Sorry to see Dave missed the finals. I really hate the idea of switching models. No matter what you do they always fly a bit different.
Practicing, Dave appeared to fly the contra better in the P and the standard drive better in the F. It was his strategy to do exactly as he did.
Nevetheless, scoring 90% to the winner's score is nowhere near where Dave normally flies F. Something may have gone wrong with the equipment
