I'm working on this one right now . . . .

A challenging project to be sure. You'll have to closely examine the plans and think things through before glue is applied. Some things shown on the plans have to be slightly modified as you'll find out as you begin assembling the parts. Example: the wing joiner tube holes in the ribs cannot be cut as shown on the parts template. See the front view of the wing to find the actual placement of the holes.

I'm going with a light set of pneumatic retracts, as I didn't want the hassle of routing the mechanical linkages.

As for flying . . . . only time will tell. I think it will come out heavier than Palmer predicts, but not overly so. I think (hope) it will work.
