Forward and back tilting rotors multirotors

Good day Folks.

Has any one built a drone where the motor arms / motors tilt forwad backwards for corresponding flight directions?

There is no tilt rotor mutlirotor currently

What exaclty do you mean by

Doesn’t seem to make much sense without a wing, and then it’s just a tiltrotor quadplane.
And no, I don’t think copter supports that kind of tiltrotor. There is a bicopter frame though.

It doesn’t need a wing.
