Here is the first drone turret. For a demonstration on how to use it, use the demo snapshot. Make sure it is anchored, and add a cab to the rig (because I forgot to do that), then remove the Venture Bracket connecting the drone turret to the rig. Next, move the EXP Medium Socket so that it intersects with the ball, then place it. After that, you will need to select the rig, and press X. Unfortunately, it seems to always cause the turret's ball to phase through the socket, so you may need to use build beam and place the socket again. The drone turret is very stable while mounted to a tech, but when driving it on the ground (while not mounted), it tends to fall over at some turns.
