Mine arrived Tuesday. Sanding and prepping for prime and paint right now. 700 Euros, comes with two 1l clunk tanks and two Multiplex 212 oz-in servos pre-installed. Add pulsejet (EU 700) + fuel pump (6v turbine pump) + brushed ESC (for fuel pump) + radio + bungee launcher.

It's amazing that what we fly is so cool that people with jets are calling them wings to bask in our glory. If that's a wing every jet ever made that isn't an F-86 or MIG 15 is a flying wing! Not........

No delta jet in real life has ever been called a flying wing because their designers, pilots, crew, designers and owners don't consider them so. You'd think delta jets, especially pulse jets, would be so cool they didn't have to glom off of our category. Apparently not......

Would a chevron with a jet engine be a flying wing or can it only be prop or gravity powered?

Well, it's called a flying wing. Any mention of power plant in there? It isn't a flying arrow like a delta jet. It's a wing! Draw your own conclusions. Then consult with any military pilot of a delta jet and ask if they fly a flying wing. Case closed.

You know the Concorde was a delta jet. Find any article anywhere referring to it as a flying wing.

Yup, exactly. There are delta winged aircraft in that book. Real live delta winged aircraft in a book about flying wings.

Gee, who'da thunk it????

Rockin Robbins strikes again, with his negative viewpoint.

Obviously a MiG-21 is not a flying wing, it has a horizontal tail.

Pulse jets sound so freakin weird! Almost sounds like a piston engine. Neat aerioplane.

Chapter 9 is mostly deltas. If you build a series of tapered planks of different aspect ratios, but otherwise the same, when do they stop being flying wings and become deltas? It looks to me like deltas are simply tapered planks with an AR of less than 2

Winged Wonders is about the Northrup flying wings. It only mentions the delta winged planes in the last chapter as a non sequitur. Even its treatment of Jack Northrup completely leaves out the political killing of the wings, the people behind the murder and the blackmail to Northrup that resulted in the story not blowing up in the guilty party's face.

Not the best book by far and certainly not an authority. Find something with authority.

As to when an aircraft becomes something other than a flying wing, when a vertical stabilizer is used which works just like the vertical stabilizer of a normal layout aircraft, as it does on all deltas model and full sized. That is not a flying wing.

A vertical stabilizer on a true flying wing doesn't work like the feathers on an arrow to keep the yaw straight. The only thing a rudder will do is induce drag. It will not yaw the plane though a torque applied to the yaw axis in the normal sense.

The flight test boys with a real flying wing put fins, winglets, whatever you choose to call them, on the end of the wing and mounted rudders to them. They deflected the crap out of the rudder, made it larger, all it did was induce drag, and since there was one on the end of each wing it never yawed the plane in the slightest. They worked as air brakes. That is a defining characteristic of true flying wings. Their aerodynamics are different than a conventional planform.

The reason the winglets serve to self-cancel yaw on a true flying wing is differential drag. They are toed in, so the leading wing presents more frontal area than the trailing wing. That causes the leading wing to fall back until the drag is equal on both wings. Vertical surfaces on the ends of the wing facing straight into the line of flight do nothing to produce directional stability.

However, on deltas, the vertical stabilizer is always aligned perfectly with the direction of travel. It works like the feathers of an arrow, not as a differential drag inducer. A rudder on the vertical stabilizer of a delta yaws the plane. On a true flying wing a rudder does not yaw the plane.

The flight test boys even mounted a horizontal thrust vector system on their true flying wing, able to point plus and minus about 30 left and right. It did nothing. That is because they were flying a true flying wing where aerodynamic principles are different than conventional aircraft.

It is the aerodynamic principles that define what is a wing and what is something else. The OP's plane is a delta. It flies exactly like a conventional aircraft. It's a lawn dart.

Everyone knows what a flying wing is. Some people think their planes aren't cool enough and want to put the label "flying wing" on them, trying unsuccessfully to be as cool. The tragedy is that they are already plenty cool without stealing the name. Very few of us could fly the OP's plane. It's a tremendous accomplishment, both in the design and the skill to fly it. But there I go being negative again.

So is this a flying wing by your narrow definition?

Pretty sure most would say it is.

Depends on what happens when you deflect the rudder. If it yaws nope. Especially if it yaws and banks because of the dihedral, nope. That would make it a conventional plane.
