My own plane landed very smoothly, and I even ran into fellow coworkers in the terminal. It's after that it's complicated. I had ordered electronic cards from two different manufacturers.

So normally, we should avoid big surprises. There are 3 PCBs (printed circuit board) in our Pioupiou: The very small one, at the front. It contains one of the battery connectors, as well as the rotation counter for the propeller. No ILS − too fragile, no sensor…
