Had one of those myself! Fortunately, the model had plenty of altitude by the time I was ready for the first turn and discovered the problem. I was able to land it in one piece.

If you can, try swapping the suspect motor with one that works. You want to rule out a bad connection or ESC.

3/4" pipe for the 30" bow, 1" for the 44". I used 1/4 steel rods for the legs with a groove at the ends for the wire. The pipe is bowed so it provides tension and takes up the slack. I should...

I use plastic water pipe (PVC) for my bows. Its light, cheap, and readily available. It doesn't conduct electricity and has the right amount of flex to maintain tension.

I use dollar tree foam for skins and I remove the paper from it, glue it to the wing ribs and then cover that with Kraft paper and WBPU.

Definitely parallel the batteries. As to inner/outer vs. all 4 on one pack, I'd go with whatever is simpler or less weight to wire up. There is some merit to what you say about having separate...

It may/will make a small difference in trim and how the airplane flies. I've tried it both ways on several twins; easy enough to do. Mostly I've prefered tips rotating inwards.

But I wonder how easy it will be to keep it level in the roll access. It looks like it will have a wicked roll rate and without dihedral, will have no way to "self correct". Maybe...
