1.14 Helicopter (tail Servo)

In 1.14 Guide, for Helicopter, If you need to use autopilot in Helicopter with tail servo, you need to change CA_AIRFRAME parameter to ‘Helicopter (tail Servo)’. But there is no such parameter, only just ‘Helicopter’. So, my question is that, in 1.14 there is no way to use Helicopter with tail Servo?
