I haven't checked the thrust loss, though I could do so once I get the engine running.

The intention is for this to go into my venerable Bobcat ... I needed another turbine for my Hunter, and I've long wanted a BMT to see if it's as good as several reports suggest, but I didn't want two unknowns togeher - so I elected to pull one of my trusty P120's out of my Bobcat, then "split the odds" by putting the known engine in the unknown airframe and vice-versa.
