This plane is my "overall" favorite because of its really tight looping and ability to fly and land at really low airspeed. It also happens to look the most graceful of the three I've built.
In this video I discuss the tips that will help you achieve the same result.
It's interesting how the same principles come into play no matter what design you choose. Whether you're doing a flying wing, canard, conventional tractor, or twin boom pusher, you still have to address the same old issues: roll stability, tip stalling, yaw stability, proper CG, reasonable wing loading, etc.
