Very clean K&B stallion 35 Chrome with black cylinder gas powered engine, clean, but when I turn the shaft, it is tight, so I imagine it will need freeing up before use. Otherwise, this very clean stallion 35 K&B gas engine, for stunt plane flying, we'll make a great addition to you vintage K & B or Stallion 35 gas powered engine or control line or stunt plane radio control airplane engine or propulsion related memorabilia collection.
