Question:
Why is the Horizontal Stabilizer Aerofoil, located on the tail section, on a Bell 407/412 (possibly others) oriented upside down (ie. produces lift downwards)?
Is this to balance the rotorcraft about the c.g. at higher airspeeds?
Cheers,

Fixed stabilizers may be found on a wide variety of light helos, not just the Bell 407/412. More sophisticated flying stabilizers are used on a variety of [mostly] military helicopters. In cruise, their function is the same as their fixed counterparts.
