I like some of the concept , but I would build the middle section with the doubler sticking out just an inch or so at each end , thus you can slide it into the rear , gives more glue surface / over lap be stronger , then add rest of doubler to front .. also a couple of weak spring clamps would help hold it while glue cools
I can't help much on the different sticks. I use either standard temp glue squirted into a puddle and allowed to cool a bit or RooClear Melamine cement. The RooClear is really good for gluing big broken pieces.
Partly to get the desired shape and partly because the tail is best as a box, while the center needs to be flat and straight with stong sides. The front tapers to a nose and needs to allow battery access and mounting while also being strong. It was easiest to do in three sections for these planes, but you may wish to eliminate or add parts to suit your own needs... I'll continue the videos soon and some of my thinking may make more sense. I apologize greatly for the delay.
