Hi David, I can answer some of your questions Yasu San will have to adress the rest.

The wing box is included. The white plastic or urithane pieces and the carbon fiber top plates you see pictuerd were included with my kit.
I don't know if the carbon weave cloth that is under the white pivots are stock of Yasu added them ... I haven't cut into mine yet.

The strut, that looks like wood, connecting the two plastic pivot blocks is not included in my kit and I suspect that it's not nessicary.
There are two carbon fiber tube supports / spars in mine. They are laminated into the shell with the fuselage bulkheads.
These CF spars look adequate to support the swing wing pivots but then again I haven't cut the large acess holes into mine yet.

Yasu San - Are you there ? What retracts are you useing ? And would you please post pictures of the bottom with the gear out and tretacted ?

Thanks,
Kevin
