I am sure that you have seen the videos with a turboprop, so it is being done. I would think calling one of the turboprop manufactures would help get the specifics for the project, since no one has answered here for a couple days. Also, I see this is in IMAC, maybe move this to Jets Forums for more of the turbine experienced guys. This one is actually under Giant Scale

Good Luck!
