This picture shows the servos fixed in position with servo tape.

To begin with I used poor quality tape to allow ease of removal after mechanically centering servo arms on first fire up of the electronics. This cannot be done with this layout without removing two of the servos.

With the servos in place the swashplate can be hooked up

The head can then be trial fitted

The tail servo is an Ashtek digital, it is fitted to the right hand side frame as can be seen here.

This saves a small amount of weight and also makes for a very rigid mount for the servo.

The tail pitch lever is linked to this servo via a carbon link.
