V3 Hand-Launch Glider – Refined Aerodynamics & Stable Flight

This is my V3 hand-launch glider, developed through multiple design iterations with a focus on real-world flight performance, stability, and ease of printing.

Compared to earlier versions, V3 introduces meaningful aerodynamic and structural improvements rather than cosmetic changes. The wingspan was increased to generate more lift and produce a slower, longer glide, while the wing chord was expanded to improve low-speed stability and reduce stall risk during hand launches. The straight wing planform was intentionally retained to keep airflow predictable and performance consistent.

The fuselage was lengthened to increase the moment arm, making the glider more pitch-stable and less sensitive to center-of-gravity shifts. V3 is designed to be slightly nose-heavy, which greatly improves launch recovery and overall flight consistency. The spacing and sizing of the horizontal and vertical stabilizers were refined to better match the increased wing area, improving longitudinal and directional stability.

This version is optimized specifically for smooth hand throws, predictable glide paths, and iterative testing. It works well both as a fun outdoor glider and as an educational model for learning about balance, lift, and aircraft proportions.

🔧 Printing Notes

• No supports required

• Prints cleanly on most FDM printers

• PLA recommended

• Low infill works well to keep weight down and glide time up

✈ Flight Notes

• Designed for stable, forgiving hand launches

• Best thrown smoothly and level

• Easy to tune by adjusting weight or scaling

V2 was a proof-of-concept—V3 is a purpose-built glider.
