does anyone know how would you create a compact gimbaling propeller, like how a rocket engine gimbals. Similar to that! Thank you for the help!!!
There are some commercial units (single axis or two axis) or there are a variety of designs you can 3D print.
These designs are mainly based around a large ball joint behind the motor, but there are some designs that use two sets of pivots like a traditional gimbal.
If you're DIYing it, a simple way to do it is two motors that pivot in one direction only, using differential thrust for the other direction.
I've also seen models where the motor mounts are attached directly to the elevons, sharing a hinge and servo.
