At last the missing parts have arrived. I was able to finish up the prototype of the electronic control unit and the uplock. It was an epic moment when I was able to run the gear through it’s entire up and down cycle for the first time.

The attentive viewer might observe that the uplock is a complete redesign. The mecanical release got replaced by a electric solenoid, controlled through relais and two proximity switches. It took me a practical experience to figure out that the latter react particularly sensitive to wrong polarity. Luckily I had ordered several of these switches in anticipation of my abilities in the field of electronics. When it comes to building the final version of the electronic controls and wiring in aviation style I definitely will revert to experts.

Slo-Mo of the uplock function
