Sherpa K650T Turboprop


Purchase the X-Plane Sherpa K650T Here

The Sherpa is an experimental design undergoing FAA certification. The aircraft was designed by Glen Gordon and Byron Root and has been on display at Oshkosh since 2008. Our version pushes the certification limits and adds bush wheel, float, and ski versions. Want all the fun without the $750k price tag of the kit? You need not look any further.

The turbine Sherpa (K650T) is our newest addition to the bush plane lineup. This amazing aircraft was designed and built by Byron Root and Glen Gordon and is now undergoing the arduous phases of certification. We tapped the Sherpa information sources and developed a set of models that closely follow the turbine Sherpa’s performance. It is impressive! With a proprietary airfoil and flap design, 3500 pound empty weight, 840 horsepower turning 110 inches of three-blade prop you know it has to be good.

Check out these stats:

      • No Flap Final – 100 MPH – 28 PPH
      • Flap 20 Final – 80 MPH – 29 PPH
      • Flap 20 Final – 65 MPH – 29 PPH
      • Missed Approach – 80 MPH, 5 Degree Climb Gradient, 32 PPH

The experimental K650T has not been seen with skis or floats but we provide you with versions for any condition all test flown in the toughest conditions to ensure you have a plane that will get you in and out of the trickiest places. Our cockpit is a replica of the experimental turbine Sherpa. In the future, as the actual birds get glass cockpits and more refined displays we’ll follow with updates. Our payload bays will come with options for hunting/fishing camp resupply or passengers and our proprietary pilot.

The Sherpa’s high visibility cockpit combined with STMA’s Tracker XP 3D plugin is sure to give you hours of realistic flight experience. This aircraft will hook you!

The Sherpa K650T now incorporates AutoUpdate (AU).  When enabled it automatically checks for updates every time you load an AU-enabled model or plugin in X-Plane.  No more worries about whether or not your model is current.   No more complex download procedures or endless inquiries to support staff.   Don’t want to update your model or not connected to the internet?  If it's a model, simply click on the AutoUpdate Dock to disable it.

How will you know if your model or plugin has AutoUpdate?   When you load the model into X-Plane you’ll see the AutoUpdate Dock above the STMA Dock in the left margin of the X-Plane window.  A momentary file update notice will appear for each installed AU-equipped plugin in the lower left corner of the screen.  If updates are available, a progress bar consisting of small pluses (+) and the file name(s) of the updated files will persist until all files are updated.  AutoUpdate also appears as a plugin in the Plugins menu.  When you select it AU's current state is indicated.

The real version kit price is $750k. You’ll get ours for the usual fair price!

Modeling and flight dynamics follow specifications and test pilot reported observations and is pure pleasure to fly. We have tested the Sherpa in all the toughest places for bush planes – high mountain strips, small lakes, and even Lukla airport in the Himalayas. The Sherpa takes off shorter than a Husky, approaches the landing field at 55 knots, cruises at 180 knots, and is limited in service ceiling only by its unpressurized cabin. It’s like a turbine Maule only bigger -- like a turbine Porter only prettier!

As the Sherpa certification progresses we will update the model for current owners so you can stay up with the actual working planes. This model is built and tested by a mountain pilot instructor for bush pilot enthusiasts, so pack your gear and let’s go! Watch for a February release.

As with all STMA models you'll get a fully functional 3D cockpit, control dock, and some extras we'll add as a surprise.
