Helifolk,
One more query about turbines for helis:
Do non-DEC turbines (like RR350 or early Arriels) require any trimming on the collective correlator, or is N1/Nr auto controlled? Is any trimming required for fast yaws? I seem to remember that a free power turbine has a very "stubborn" torque vs RPM gradient to resist RPM changes.
