The development of the semi and rigid rotor systems cultivated thoughts in the minds of some helo pilots that at last the machines could be aerobatted. Alas those that advocated this capability stop well short of considering other factors, as Mr Coyle points out - engine/transmission oil system limitations, airframe build limitations, the rapid bleed of energy etc. The galahs that support the the aerobatic capabilities of helos are the same ones who contiually ignore other limitations. Generally these pilots have not been trained in F/W aerobatics and have absolutely no idea of the flight regime they are entering.
Leave aerobatics to the pilots who have the skills in machines designed for the task.
Consider your future - you are certainly not cut out to be helicopter pilots!
