Is KiteFlyPro completely free?

Yes! All 6 tools – Flight Calculator, Duration Estimator, Material Calculator, Festival Planner, Kite Designer, and community features – are 100% free with no login required.

How accurate is the kite flight calculator?

The flight calculator uses established aerodynamic formulas including lift coefficient, drag coefficient, and air density (1.225 kg/m³ at sea level). Results are validated against published aerospace engineering references and are accurate for recreational kite flying.

How do I submit a kite festival?

Navigate to the Festival Planner page on KiteFlyPro and click Submit a Festival. Fill in the festival name, location, dates, and organizer contact information. Submissions are reviewed within 48 hours before appearing publicly.

What wind speeds are safe for kite flying?

Generally, 10–25 km/h (Beaufort scale 2–4) is ideal for most recreational kites. Very light winds under 5 km/h or strong winds above 40 km/h can make flying difficult or dangerous. Use the KiteFlyPro Flight Calculator to check specific conditions.

Can I download my custom kite design?

Yes! In the Kite Designer tool, after completing your design, click the Download PNG button. Your kite design will be exported as a high-resolution PNG image you can save, print, or use as a building blueprint.

How do I calculate kite lift and drag?

Use the KiteFlyPro Flight Calculator. Enter your kite's sail area, weight, wind speed, and angle of attack. The calculator applies aerodynamic formulas to compute lift force, drag force, and line tension in Newtons, along with a Beaufort wind scale rating.
