Another view inside the control box of the pneumatic wings from The Rapture.  Two micro servos operate 4 switches that control the pneumatic system.  All operated by remote control.  You can see the Futaba 6 channel receiver hanging out on the right.    The pushrod connectors were added because the servo horns deflected off the switches.  In the back you can see two 9 volt batteries that powered the electronic valves, and the top corner of the RC battery pack.  These were mounted in pouches outside the case.
