I fly regularly with helicopters (just 4 days ago with an AB212), but
unfortunately I don't usually pay much attention to this. Mostly
they do pick me up with running engines and rotors. I remember,
though, that an AB204 pilot started the engine first, and *then*
clutched the rotor -- not at 100% engine power, of course. Also,
one of the best helicopter sims (SAR II demo; not v1 or v3, both
of which are crap) did it that way. Anyway, as I'm no helicopter
pilot, I'll better ask a RL Bo105 pilot and adapt the Nasal-fake
startup procedure accordingly.

Because I do think that the engines should be started first.
And because the YASim rotor code doesn't allow to control
the rotor RPM. The acceleration from 0 to the hard-coded
RPM is done by the FDM. I'm still waiting for someone who
is able and willing to finish the half-done helcopter
FDM. I'm just willing, but unable. :-]
