Hi Rob,

As Syd said, a YASim aircraft doesn't use the YASim fixed-wing engine
declarations, but uses a different set of specifications for the rotor
and its drive train. I'm not a helicopter developer, so I can't help
with details of rotor stuff, but maybe Heiko other helicopter gurus
will drop in with comments.

What I can say is that you don't have to rely on the YASim FDM to do
all the simulation and in some cases you're better off not using
YASim's results. For my own projects (fixed-wings), I'm increasingly
taking engine parameters into my own hands, crafting my own code
(nasal scripts) to supplement, modify, or replace the engine
parameters YASim provides. If you want to simulate a helicopter engine
you could write your own routines to manage the engine itself;
temperatures, pressures, RPMs, start-up, shut-down, fuel, that sort of
thing. Some things might link to YASim's rotor outputs, like RPMs etc.
Others might be managed separately with no FDM dependencies.

Since you're fairly new to Flightgear it may take a little while to
get comfortable with all this. If you study the configuration files of
many planes and helicopters, you'll encounter a lot of clever ideas
and solutions. There really aren't many restrictions other than what
you are willing to do. That's kinda the cool thing about Flightgear.
