No matter how you do it plywood sucks. It is going to be slow. Rigging a tail sometimes helps it fly a little straighter. Just go slow.
Poles: depends if you have to set them or not. rig a cross bar at the top and attach from either side. I have flow tem with just one chocker or horizontal with 2 chokers.
Cabin, com shells, etc. Four points , make sure the rigging is strapped together so the structure cant tipp to one side.
