X-Plane 10 Models:
We have decided to stop creating models in V9.7 and to concentrate all of our efforts on V10. There will be one more V9.7 / V10 model, the Sherpa K650T, which will be released in the very near future. All future models will be designed in and for V10. However, we will continue to support our earlier models and fix all identified bugs for their lifetimes. Note that we recently culled a couple of older models from our active inventory and may make further cuts as we get deeper into V10.

Further, we have successfully developed and released 64 bit versions of all of our plugins and add-ons. See our Plugins Update Bin for details on all plugins.

Batch Airfoil Update:
We strongly recommend that you open V9.7 Airfoil Maker and do a batch airfoil update on all of your custom models before copying them in to X-Plane V10. If any of our airfoils fail this test please notify us immediately..

Sherpa K650T Turboprop V10

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:

  • Takeoff (Half Fuel, Std Day, 2000’ MSL)
    • No Flap lift Off and 60 MPH in 320 Feet
    • 20 Flap (Optimum) Lift Off at 43 MPH in 200 Feet

  • Distance to Clear 50’ Obstacle (Half Fuel, Std Day, 2000’ MSL)
    • No Flap 60 MPH Climb Requires 800 Feet (30 Degrees Nose High)
    • 20 Flap (Optimum) 50 MPH Climb Requires 510 Feet (30 Degrees Nose High)

  • Landing (At Touch Down - Full Reverse Thrust No Brakes)
    • No Flap – 70 MPH Approach at 3 Degrees – 450 Feet
    • 10 Flap – 65 MPH Approach at 3 Degrees – 300 Feet
    • 20 Flap – 60 MPH Approach at 3 Degrees – 280 Feet
    • 30 Flap – 55 MPH Approach at 3 Degrees – 170 Feet
    • 40 Flap – 50 MPH Approach at 3 Degrees – 150 Feet.

  • Landing Over a 50 Foot Obstacle
    • 40 Flap, 10 Degree Approach Angle at 60 MPH – 640 Feet.

  • Besides being a great plane for the bush, the Sherpa also has docile and predictable instrument flight characteristics:
    • Vectors – 120 MPH – 29 PPH
    • 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 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.

Tracker XP
I bought TrackerXP yesterday -- and it's working great! After only 5 minutes of use I can't imagine to go back. It's SOOO good to be able to simply turn / move the head for looking out of the windows instead of pressing keys. Much more immersion! Thank you for this great addon!

Pilatus PC-12
I'm really digging this PC-12 version.

I'm an aerospace engineer, specializing in aircraft performance. I just wrapped up a PC-12 project which required digitizing some of the POH performance. I just spent an hour or so comparing the simulated performance climb, cruise, and descent performance against POH values and must say, I'm impressed with how close things track the POH values. I have not yet looked at field performance, but will try to get to that tomorrow.

Overall, very nice job in every respect! Well, well worth the cost in my opinion. And so much fun to fly because of the realism modeled!.
Aviat Husky
Thanks for the great conversion of the Aviat Husky, it is the best aircraft release that i know for X-Plane! The model and the cockpit are very well made and it flies fantastic.

Greetings from Germany
Aviat Husky
I just got around to checking out your Husky and it's simply a beautiful model. X-Plane designers have come a long way since I first starting toying around back in V6. This model is worth every last cent! Thank you for your work, and providing several different models to boot!

Jason Baker
Thank You!
Thanks for all of the timely updates and for taking your time out to make a modification like this to help those out who were unhappy with the reflections. I love them myself but you RARELY see anyone give you the best of both worlds.

Keep up the good work and with these speedy recent updates you have a customer for life in me! :)

Glass Objects
Hi Peter and Jim, just wanted to let you know that the new glass object works PERFECTLY! I no longer have the tearing like before and everything is great.

Thank you so much for making the extra effort to fix it. This is one of my favorite planes and it's great to have it working properly.

And Peter, keep up the great work on those liveries! They're really beautiful and add a lot to the plane.

Cheers and thanks again,
Everything is working well. I have just programmed some keyboard commands as you suggested and boy is this easy and fun to do. Sure makes parking a lot easier. ( wanders off into dream-- wonder if I can do something similar to help park the car in the driveway ..... )

John Pugh
Super Cub
I can't say enough good things about this plane. I have a private pilot license and a flew a 1946, 90 hp, Piper Cub, 30 years ago and this model seems to be so true to my memories of that flying experience. Well done! I love the 3-D cockpit and the way that I can switch viewing angles so quickly and easily, almost like the real deal. I also logged quite a few hours in a Cessna 182, so after the Cub, I also bought the Skylane model. I know is slightly older model, but still another great plane.

Keep up the good work.

Best Regards
Thomas Buckman
