>ionic wind is at least 3 orders of magnitude too small to explain the magnitude of the observed force
But did they assume you need collisions of ions and neutral atoms?
Did they take into account that the action-reaction forces of just the ions could provide thrust?
The biggest forces on the ion are around the (+) electrode, the force on the ion is much weaker on the (-) electrode. It just needs to gently graze the electrode and keep its momentum while hardly affecting the electrode. And once the ion takes an electron off the (-) electrode it stops being affected by the electric field and can keep going.

It's theoretically so easy, just a generic capacitor, why did no one test it at home? You don't even need a pulsing power source. You only need to test the behavior when charging, discharging. Don't even need a vacuum. Just hang it and test if it moves at all in air. A generic symmetrical capacitor will hardly cause ion winds.
