So haven't finished reading it yet...but found two things on page 19:
1) You have the pitot heat switch in there twice
2) They Hydraulic test switch is currently not modeled.
Page 43: The fuel lever need to be moved forward until rotors start spinning, then wait for turbine and rotors to sync, then slowly move fuel lever forward. In the next update if you pushed the fuel lever forward to quickly it's kill the engine...and you'll get even nastier looks from the Commander.
Page 57: Seems like you copied the Huey info, since you actually apply right rudder, not left during hover. If you used left, you'll find yourself spinning quite a bit more.
Page 63: The Gazelle has an auto-throttle system, so to induce auturotation your shutting fuel flow, not really reducing the throttle....more semantics.
Page 89-90 seem to have same info...different pictures.
Will post if I find anything else
