Scratch Build RQ-7 Shadow Composite/Balsa

Hey there guys!

Alright, So I've been researching and planning a complete UAS system for over a year now and did not find an airframe within a resonable price range to fit my needs so I decided to Build My Own!

I have some general specs and will possibly turn this thread into a build log when I start this project.

Wingspan: 96"
Wing Chord: 12" Constant
Airfoil: NACA 4415
Fuselage: 42"x6"x6"
Empennage: Twin-boom Inverted V-Tail
Power System: 45-55cc Gas with Generator
Material: 7075-T6 Aluminum, Carbon Fiber, Fiberglass, Wood
AUW: ~10lbs (Material Dependent)

Ultimately it will resemble the RQ-7 Shadow. I'm looking at perfecting this design, building with composites and adding my own Electronics package and GCS.

Here's where you guys come in. I've built a few planes here and there but nothing this large so I need some structural advice and building tips for this large airframe. I'm fairly new but I'm also a very quick learner. I have a military background and experience with UAS platforms.

FYI: I'm looking for professional style structural building. I'm going to be adding ideas and could use some experienced input. I understand weight is a limitation but can adjust for heavier weight but stronger structural techniques.

I look forward to reading the posts and replies!

I like it! I'm trying to build one out of foam.

How do you plan on attaching the twin booms to the wings?
