I'm about to start a new project: a JHH A-7 edf to turbine conversion. There are two engines I'm considering, the Kingtech K-45 and the kolibri T-45. The T-45 is much smaller and lighter, which could allow me to place it further rearward than the K-45. But, before I consider spending the extra many hundreds of dollars on the Kolibri I was hoping I could try it out, so to speak, for fit and balance.

That's where 3D printing comes in: I figure I could print out a couple dummy engines and load them up with weight to stimulate the engines I'm looking to use.

Now my question: does anyone have STL files for either, or both, of these engines? I suppose I could make my own based on the specs and drawings, but I figured I would ask first.

Also, would anyone else be interested in relatively inexpensive dummies of popular engines before investing in the real thing?

Thanks

Frank
