I don't know if anyone has done this yet; I haven't seen any, so I'll assume no.
These are overall pretty sturdy battle/exploration builds: the armored version lasted 90-100 seconds in the Arena, and I usually use the unarmored one for the "Destroy Transmitter" planets. I have another similar but slimmer digging drone.
My "innovation" is the OR gates that control the thrusters: instead of having independent thrusters for turning left and right, I simply hook it up so that the upper-left and lower-right thrusters fire to turn counterclockwise, and the other two corners to turn clockwise. Forward is just the two bottom thrusters, and down is the two top thrusters.
This gives me pretty good maneuverability and thrust since I can install less thrusters for more speed. The gates double for armor; if they break I just use manual control. The drone is, in my opinion, fast enough for any purposes but not such that I crash into everything. I use the same system for all my other drones, and it works pretty well.
