Last time, I built the test model for a tailsitter VTOL - a pretty rugged model. Yet, it does not bother me. I wish to connect all the electronics and see if this can exert some force and torque onto the body regardless of the ability of attitude or angular rate control.

Also, I noticed that the rotation point should not be at the bottom. Instead, it should be at the nose, as the center of gravity is much closer to it.
