Proper Pawn Set up for Motion Controller Use

I am having some issues with getting motion controller tracking working with 4.10.1.

The two resources I have used are the documentation here: https://docs.unrealengine.com/latest/INT/Platforms/VR/MotionController/index.html and the video here: Setting Up VR Motion Controllers | Live Training | Unreal Engine - YouTube

One difference I have noticed is in the video Sam Deiter adds the Steam VR Chaperone to his Pawn as a component. Something not mentioned in the documentation.

Regardless of addding it or not I see zero movement of simple static meshes I have added as children of the motion controller components. Tracking of moving around the space / looking around works just fine as does the SteamVR tutorial.

I am basing my Pawn on DefaultPawn. Here is the setup:

Any advice on setup, debugging / troubleshooting steps or a sample project to test with beyond the links above would be great!
