FAA DAR Gyropilot
It's been a while since I've danced with my first true love, the mighty MAC engine. I have David Praters old "Iron Rooster" in my shop for an electric starter installation and general return-to-flight restoration. For the life of me I can not find the prop bolt torque (wood prop) or the hub retaining bolt (into the crankshaft) torque numbers. Any help or directions are appreciated.
