Park Pilot: 3D Printing

Don Slusarczyk discusses his experience with 3D-printed tires made from foaming TPU, which offers improved softness and flexibility compared to traditional TPU. He details the printing process, settings, and challenges, including reducing extruder spring tension to prevent jams. The final product resembles foam tires and costs around $1.25. He emphasizes the importance of sealing TPU filament to prevent moisture absorption and highlights the lengthy print times required at slower speeds.

Indoor Free Flight

In "Indoor No-Cal Trimming Techniques," Don Slusarczyk discusses optimal trimming for Indoor No-Cal models, advocating for right-hand circles contrary to the common left-hand flight. He recommends a 4° decalage between the wing and stabilizer, with specific adjustments for thrust, downthrust, and rudder offset. Slusarczyk details wing washin and washout strategies, emphasizing the importance of balancing these elements to achieve consistent right turns. He suggests testing under low power and adjusting ballast as needed for optimal performance. The article provides a comprehensive guide for achieving effective trim in Indoor No-Cal models.
