I Love Delta Wings (and so should YOU!)

The title says it all. 

I'm going to classify blended wing body type planes under this category, too. If you get the dimensions right and the CG nose-heavy enough, they are some of the best flying planes out there. In fact, I've come up with all of the dimensions for my delta wings and BWB's and they fly better than store-bought planes!

I wanted to make a thread to show off my new Delta FPV Plane (actually it's just aerial video but still first-person-view), but then I realized I should show all of my delta wings and BWB's. 

I believe that simplicity is best. 
A delta wing is extremely simple to make: just a triangle, 2 servos, a rudder, and a couple strips of foam for a fuselage underneath. I have stumbled upon what I call the "perfect dimensions" for a delta wing.
These are the dimensions for my Delta FPV:

It is the largest delta wing I've made, and you also saw the smaller one in the picture above. So anywhere from (24in WS 21in long) to (40in WS 30in long) should work. The important dimensions are below, and if you don't want to make it this size, scale up/down each dimension by the same factor. The rudder dimensions can be more custom, but the larger the better.

What makes these planes fly so well? 
The wing is very efficient; almost all of the body is contributing to lift. The KF airfoil gives it good roll stability and makes the general characteristics very predictable and locked-in at slow and high speeds. The large rudder makes the plane track very straight.

Performance:
The design is so stable that I would recommend it for beginners.
It can handle low and high speeds very well.
If the motor is mounted in the middle, you get constant airflow over the elevons. This results in GREAT high alpha performance.
Flick the switch for high rates and you have a plane that does excellent loops and rolls.

BWB's:
These are a mix between flying wings and delta wings, so I figured I should talk about them, too. Getting the CG correct is the most important thing when designing one. Nose heavy is key, tail heavy is disaster. The yellow stick in the picture below shows the CG position on the plane, note how far forward it is on the main wing:

I couldn't get it to fly as just the pink wing since I couldn't get the CG forward enough. That's why I modified it into a BWB of sorts, the canards act as more stabilizers. It flies really well, and it slows down so well that I catch it out of the air every time I land.

Thanks for reading, hope it inspires you to make a simple delta wing!
