Plywood sides for lift fan cutout

I've added some plywood sides for the lift fan cutout. Reinforcing the strength of the hull for the extra stressed sections, and protecting the foam some more.

Round 1:

Round 2:

Due to a lack of clamps I had to do this in two shots. And each piece only got 3 clamps. I had to go back and do a little rework to reglue a few corners where the plywood warped or the underlying surface was slightly recessed and I needed more localized pressure.  Another improvement would have been to use 6" backing boards for applying the pressure to avoid the warping. However I didn't have any on hand so I just went ahead with the direct clamping.

Here's a photo of the touch up I did, after flipping it back over.
Gluing down a few extra corners.
