Controls

Done practicing. A little bit of sheet metal to manufacture the combo bracket, that holds the main control unit and the HEI and will attach to the forward bottom edge of the airframe.

If that sounds too much like some fancy h-e-licopter lingo, here's the translation:
1) main control unit = laptop
2) HEI = human-e-copter-interface /controls = joystick
3) airframe = office chair
