Robinson Symmetrical Stabilizer Acquires New Approvals

Regulators in Argentina, the European Union, India, and Japan have approved the improved empennage on all models of the Robinson Helicopter family, including the R22, R44, and R66. The new empennage is standard on new Robinson models (R44 and R66 in Argentina; R44 Raven I and R66 in India; and R22 and R44 in Japan) and includes the symmetrical horizontal stabilizer and tailcone. 

According to Robinson Helicopter, the symmetrical horizontal stabilizer improves roll stability, “particularly during high-speed flights, [and] it contributes to a smoother and safer flight experience. Additionally, the symmetrical stabilizer helps reduce the right-rolling tendency when the aircraft is operated outside of the approved flight envelope.”
