Should have been around when we flag tracked the main rotor and poked checked the tail rotor
Ah yes! Poke checked the old B212 tail rotor many a time. Procedure: tape a wax pencil on the end of a broomstick. Crank up the machine, 100% rpm.
Head to the back and first heat up the wax pencil by sticking it in the PT6 exhaust flow for just a sec or two.
Then, down to the tail rotor. Hold the broom stick ever so carefully against the fin's trailing edge, and guide it in until the wax pencil just hits the rotating T/R blades.
Shutdown, check markings, adjust, repeat. Beats working in the hell hole anyday.
