Yeah,, he put those on just before the Nats. His fine tuning of his planes is pretty cool. Hes really in tune with what the planes doing and what modification they need. On one of the planes he was working with earlier this year, he thought it needed a little more thrust angle on the C50 that was in it. He looked around on the ground and saw a little piece of matchbook paper, Shoved that in the rear rubber mount to add a teeny bit more right thrust. Took the plane off and pulled a couple of lines, Said "there, thats just about it." !!!
