I'm still trying to decide what kind of engineer Al is; you can't tell from his posts. He demonstrates not just knowledge but expertise in mechanisms, drive systems, controls, programming, electric power, electronics, telemetry, fabrication and machining, physics, psychology, where do I stop? I frequent the technical forums to see if I can contribute, but usually Al has beat me to it and his answer is far more detailed and concise than I could ever produce.
Wildstangers, I hope you realize what a treasure you have as a mentor. It was my pleasure to officially meet him at nat's last year. Congratulations Al - you've raised the bar again.
