MIP First Officer’s upper panel

MIP FO's Upper Panel - A Boeing 737-800 Homecockpit #78

The first officers upper MIP panel is nearly the same like the captains panel. But there is this brake preassure gauge. And this was a big challange for me this time. It was the first time I used a stepper motor in the cockpit. It worked great but there are some things that you have to keep in mind when you are using those endless turning steppers. There is a switch needed that tells the motor when it reaches its zero position. In my case I used an optical sensor that wasn't supported by MobiFlight out of the box and I had to become a little bit creative during my configuration process.

But at the end the result is looking fantastic. Especially this three colored gauge plate comes out really nice. Another beautiful part has found a place in my cockpit.
