ooooo errr that's a lot to get my brain around. but I will eventually
The lynx engine (Gem42) is a pretty elderly lady so fadecs were not on the scene, phew one less thing to worry about, a simple fuel_controller should be ok. Tweaking the values you mentioned should help. I have replicated the full fuel system and all values seem quite stable so will leave that in for the moment. DC and AC systems coming along nicely, In reality the Hyd packs and AC gens are mounted to the front of the gearbox, driven by either engine through some free wheels etc, would this be possible with the heli system
I still need some form of output shaft to link it all to, ie a main gearbox/rotor system. I guess this controls the torque output as well which is why they max out on the gauge.
Thanks again, steve
