This problem is addressed in Update 4, which came out today. Here is the relevant language:

The following changes have been made to The Robot Section 5, now at Rev D:
<R43> Additional Parts:
Change the reference to servo type (in Bullet 1) from HS-322S to HS-322HD. The only Hitec
HS-322 servo model currently available in stores is the HS-322HD (same item as supplied
in the Kit of Parts).
<R43> Specific items allowed include:
• Additional HITEC HS-322HD Servos.
