Here are some pics of the Trimotor that that I'm working on. Not sure how long it will be until I can release it.
I've added the high speed prop disks to the model myself; the rest of the model is unchanged so far. You can see there are still some shading issues, but I'll fix those soon. Right now the the model has roughly 8,500 faces total and there will be less by the time I'm finished.
