WLM/HDNZ,
The engineer I flew with the other day said that they often had to track/balance the R44 according to the task they normally flew; ie an R44 can be sorted for a typical flight of 100kts at MAUW, but would be terrible at (say) 80kts low weight. Or could be tracked perfectly at 80kts and dreadful at 110kts.
Beats me. I've never come across such weirdness in S76/S61 - wonder what's different about the 44 (apart from being a Robinson). Most helicopters are the same I thought, push one lever and pull the other and they all seem to work in a similar way....
Cheers,
WW
