This plastic 1/10 scale model is a recent reissue by Atlantis Models of a much older Revel kit. It is a model of an Allison 501-D13 turboprop aircraft engine. Real versions of this useful engine have been in continuous production since 1954 with thousands of them still in regular service both in commercial and military use. This rugged workhorse is very efficient for low speed transport and has a great safety and maintenance record. Current versions of this engine are produced by Rolls-Royce. The basic engine specifications are readily available online so I won’t repeat them here.
I chose this model with a specific goal in mind. I wanted the challenge of adding lights, sound and motion that would be controlled by software. I almost set the bar too high. The problem turned out to be finding a motor with enough torque that would fit the space I had to work with inside the model. It took many months of trial and error with way too many small motors now left over. I almost gave up but am glad I didn’t. I have included a video so you can see and hear the results of this model work. I also added an educational voice over to point out some of the engine’s features. I learned a lot about turboprop engines during this build but probably even more about small DC motors and types of electronic controls.
The first part of this video is an engine run up sequence. After that there is a short description of the turbojet sections. Be sure to have sound on.

Excellent build, Great ingenuity. You did a good job hiding cables etc. I’m building same kit sept 24 . Think I’ll be happy with manual human drive power. A Fun intricate kit.

Thanks for your comment Doug. I learn new things with every model project. This one was a real challenge to motorize and I probably spent way too much time and money doing it. But it does make me smile. Have fun with your build !!!
