Elevons question ...

Michael · December 28, 2016, 02:18:57 PM

I'm building a Phantom jet which, for simplicity, uses elevons only.

Please confirm for me, they work like elevators and ailerons:

... the back of both elevons up = up elevator;

... the back of the right elevon up, and the back of the left elevon down = right roll.

Right

Correct.

Simon, Micheal wasn't asking a math question. Micheal was asking if it was "right".

Micheal, 'Right'!

And once you have that down pat, you're on your way to delta warwing combat.

When you say "Phantom" do you mean an F4?
If so I am not sure elevons would work as you are expecting them to. The stab would prevent any pitch change.

Yes, Phantom F4.

The stabilizers/elevons are "full flying".

Approx. 56 inches long, E-Flite 80mm fan and 80 amp ESC, E-Flite 46 electric retracts with steering servo, elevons (no rudder, no flaps, no ailerons).

It's very (relative to other model jets this size) light, and it will probably be able to fly slowly (for a model jet).

Yes, Phantom F4.

The stabilizers/elevons are "full flying".

Those are generally called "tailerons", they will work as described.

I didn't know that.

Thanks, Pat.

So, a stabilator or full flying stabilizer/elevator becomes a taileron and an elevator becomes an elevon when adding aileron function? Or...
