I'm not a huge fan of adding a lot of pedal while shutting down only because your putting stress on the tail boom and attachment bolts(yaw thrust being applied at the end of the boom but skids not allowing the turn) i just dont imagine that being too good for the mounting bolts
I always thought that this is exactly what the tailboom was designed for? What do you do if you want to climb - just let the machine yaw right, because left pedal would put too much stress on the tailboom?
I don't agree with you lelebell but I agree with Army av8r, too much left pedal overtime would put stress on tailboom attachments, think as flying with the aircraft out of trim... not just counter torquing the main rotor as you would climbing.
