Help needed from those who have played with the beasts !
MR ips in hover under .1 ips , tr .05ips as ac accelerates to 60 kts tr .2 ips, 80 kts .4 ips 120 kts 1.2 ips
the problem area appears to be something between 235 to 245 rpm causing an intermix between main rotor and tail rotor, any ideas before we set fire to it ???
