The Piper PA-28 Cherokee is a family of light aircraft designed for flight training, air taxi and personal use, built by Piper Aircraft. In 1978, Piper upgraded the Warrior to 160 horsepower (119 kW) PA-28-161, changing its name to Cherokee Warrior II. This same aircraft, now available with a glass cockpit, is available as the Warrior III, and is marketed as a training aircraft.

Development status/Issues/Todo

Outside:

  • propeller is not visible (transparent) when rotating
    • (dpm) IRL, I find the propeller effectively transparent to the human eye at cruise RPMs (>= 2100 rpm); a camera will catch it, though
  • flaps are moving in steps, they are not fluxional animated
    • (dpm) the animation would have to be very fast -- they're not electrical flaps like in the 172, but operated by a manual bar, so a change in flap position would be < 0.25 seconds (as fast as your arm can pull)
    • (dpm) the flaps should make a metallic "clunk" noise rather than an electrical "whirr" noise when being changed
  • wings and wheels are not textured

3D Cockpit:

  • cockpit instruments look flat, they don't have a 3d look
  • cockpit is not textured
  • no pilot or co pilot present
