I finally got around to swapping out the LAs for pneumatics. I didn't put in an onboard compressor because I'm eventually going to mount this plane on a control mast like Sariel's famous SR-71 setup. It takes quite a bit of pressure to get all the gear to fully extend but they move fast, almost too fast. Here is a video I put together:

I modified the cargo plane by removing the motor-driven linear actuators that raise and lower the landing gear. I replaced the actuators with pneumatic cylinders. I also removed the opening nose function which I think is unnecessary on this model. I'm also in the process of adding PF M motors directly into the prop engines and I want to change the rear cargo from LA to pneumatic. This video shows the outcome of the landing gear modification and some photos along the way.

I'm wondering if anyone has thoughts on the use of linear actuators vs. pneumatic cylinders for the landing gear? You would almost need a compressor aboard the plane but I think the landing gear would be better if they raised and lowered much faster than they do now with the actuators.

Yes, it's called Lego Crazy Action Contraptions and you can find it on Amazon. Many of the "contraptions" are very basic but I've had fun just building MOCs with the parts.

Your landing gear systems are fantastic! Loved the YouTube videos.

I had been thinking about gears and how they work and was reminded of the LEGO Technic sets I had in my childhood. I bought a book that came with about 100 Technic pieces and used that to experiment with gears. I was immediately hooked again! When I was a kid, I loved building planes and other vehicles with LEGOs and I found the LEGO Technic Cargo Plane (42025) that came out just this year so I ordered it. My build is just getting underway as of today and I decided to join this forum as well.
