  1. Here is an update on the modification of part M20. This 3D-printed part has been painted, and I have added two 4 mm diameter brass pulleys.
  2. Here are some pictures of the new control stick in position, though it hasn't been glued yet.
  3. I made a slight modification to the fuselage to accommodate the new control stick mechanism. Specifically, I removed material from the L1A wooden piece (as indicated by the dashed lines in the image below) and replaced it with a T-shaped part designed to hold the horizontal axis of the new control stick.
  4. And this is how it is installed and glued in the fuselage of the aircraft.
  5. Here is a comparison of the original photoetched and the new (painted) central lower part of the fuselage, which serves as a conduit for all the cables that control the rudder and elevator.
  6. Thanks! I hope all this effort pays off at the end and that the commands will be fully functional. Someone (Gary) in this content recently pointed out to me that once the aircraft is finished, the rudder pedals won’t be reachable with a finger!
  7. • The total length of this part is 35 mm. • I used eight pulleys, each with a diameter of 3 mm. The hole (axis) of the pulleys is approximately 1.6 mm. • For the axis, I used a 1.5 mm diameter piano wire.
  8. Here are the details of the next modification required to achieve a fully functional aircraft. This section of the aircraft, located in the central lower part of the fuselage, serves as a conduit for all the cables that control the rudder and elevator, guiding them toward the rear of the plane. The current photoetched part (parts B47 and B46) appears too sharp to accommodate moving threads safely. The objective is to rebuild this component with pulleys to facilitate smoother thread motion and prevent potential thread damage or cuts.
  9. I have 3D-printed and assembled the parts that make up the control stick. It includes three piano wires: - one with a 1.5 mm diameter for the long horizontal axis (ailerons control) - one with a 1.5 mm diameter for the stick itself - one with a 1.0 mm diameter for the smaller axis, which is perpendicular to the long axis (elevator control). The short video demonstrates how the two axes work together. IMG_9108_edited1.mp4
  10. While waiting for the pulleys I ordered, I’ve been focusing on the new control stick. I started by creating detailed technical sketches to ensure the mechanics are well thought out. Then, I modeled the parts in Fusion 360. Next, I’ll 3D print the components and incorporate piano wires for the rotating axes, using 1.5 mm and 1 mm diameters. modeled_control_stick.mp4
  11. This is the 3D-printed M20 part I designed in Fusion 360. For reference, I’m using a Uniformation GK2 resin printer with Siraya Tech Blu (Nylon Black) resin, which should be well-suited for mechanical parts. The part measures about 40 mm in length. I’m still waiting for the pulleys I ordered, which should fit into the two slots. The axes, 2 for the pulleys and 1 for the rudder pedals will be 1.5 mm piano wire.
  12. For those unfamiliar with how both old and modern planes are controlled, here are some sketches I’ve made to help explain or clarify.
  13. Thanks for the image. Indeed, it will be difficult to access the rudder pedals.
