The first iteration of the TPK series of turboprops, the Allison TPK 90 is a new experimental 6 bladed high power turboprop that I built for the purpose of replacing my bulky and inefficient turbofans, and for the 1 year anniversary of this account. It works using a fuel cell, jet engine and a propeller, which means it also produces a little extra power for the craft. It performs well with good thrust and fuel burn, along with it's compact size and light weight of 600 kilos. Juno gets finicky with using wings as blades, so it needs a freakish amount of torque to spin, so adjust it if you're using different blades. It also has some internal plumbing that you can look at, that's pretty cool in my opinion.
Specs:
Thrust: ~ 30 kn (Higer at speed)
RPM: 800 (Higher at speed)
Blade Diameter: 3.8m
Blade angle: shallow
Fuel type: Jet fuel
Fuel burn: 0.7t/h
Suggestions will be appreciated.

Maybe make the fan blade angles adjustable tho (to make reverse possible)

@PZLAgencies I did want to do exactly that, but then it started doing strange things above 300 rpm and messed up the thrust, so I scrapped it.
