Instead of simply relying on what others say, you've done tests and found the effects of <cruise....> on the FDM helicopters. In my case, I'm sorry, but I have a lot of trouble understanding Yasim for airplanes, helicopters, so for I may take a long time to achieve something for helicopter :(
One thing is for sure. Yasim is an excellent engine FDM, but it lacks developers to correct and improve all that. Regards.
