The Cat-Proof Castle, Sbach Mod

I am building the second Sbach 70, and to keep the cats off of it (they like chewing them...), I built a castle around it. It worked!

One of the things I learned with the first one was that the metal used for the elevators (one has servo control, transfers the movement to the other with a U-wire). I took the wire and soldered a heavier steel rod to it as an anti-torque bar. Works great!
