The Pedal Adjust Handle is used to place the rudder pedals at the desired position. When pulling the handle out, the rudder pedals are released, and due to spring force moved toward the pilot. Using the feet, the pilot can now adjust the wanted pedal position, which is locked down, when the handle is released.
The handle is located in the Centre Console on the bottom left side of the pedestal, near the pilot's left leg.
The models were created in Blender 2.79 for the Cycles engine, the textures and materials are PBR based. The models have been rigged with simple Empties for easy animation.
I tried to keep all the materials packed within the .blend but if for some reason it is not here, you can find them on the Texture folder in the .zip file that accompanies this panel. If for unforeseen reasons it is not found, please don't hesitate in contacting me.
NOTE: although the rig is quite simple, feel free to modify or change to whatever requirement that suits your project.
