You mean that guy left the club here and is now in Minnesota?

We have a couple that will coach you on everything from engine tuning to aerodynamics to flying. On the rare occasion they actually fly though you notice that their engines are lucky start then they cough and sputter the entire flight and the guy is darting the plane all over the place before it even leaves the ground, they bounce every landing like a basketball (if they manage to find the runway) & break a prop almost every flight. They're "experienced" though and can show you a thing or two, just ask them. I feel like hiding under a table when they fly. These are ususally the same guys who rant and rave about a a really good aerobatic pilot somehow being "unsafe". I just tune them out and fly.

As for the coordinated turns, some planes obviously require it but I don't understand why some people seem to be so hung up it though.
