how are the properties of canards affected when they are angled compared to normal canards?
When you have horizontal stabilizing surfaces with dihedral/anhedral, there is an effect on yaw stability from the effective vertical profile created by the angled surface. That vertical profile is as ...

Would aft stabilisers, that can move up and down, have any benefits?
While clearly a disadvantage during take-off and landing, an anhedral tail would be rather helpful at supersonic speed.
Vertical tails pointing up produce a rolling moment which runs counter to the ...

Would aft stabilisers, that can move up and down, have any benefits?
Yes they have a benefit, as demonstrated by the F-16 all-flying-tail (the stabilators) for almost half a century.

Vertically moving wings
No there would not be much benefit to change the incidence angle of the main wings in flight. Dihedral plays mainly a role in passive lateral stability, and there are quite a few fighter planes around ...

Vertically moving wings
If you ever wonder what different types of wing motions are good for, look at birds. They use all of them.
In this case it reduces lift while keeping drag the same. Birds use this when landing. It ...

Would aft stabilisers, that can move up and down, have any benefits?
An advantage of aircraft without vertical stabilizer is their lower radar signature.
A disadvantage is the poor stability on the yaw axis, which can be compensated by vector thrust or split elevons, ...

Vertically moving wings
The XB-70 had wingtips that folded down in flight so it could use the shock wave to create additional lift. However this particular approach (compression lift) only applies to supersonic airplanes.

Would aft stabilisers, that can move up and down, have any benefits?
Yes, absolutely. They are called elevons and can be found on many delta designs.
Elevons can function oppositely as ailerons, or together as an elevator.
The benefit is that, at very high speeds, ...
