WING LOADING CALCULATOR
WING LOADING & STALL SPEED ESTIMATE
All-Up Weight (g)
Wing Area (dm²)
Wing area in dm² (1 dm² = 100 cm² = 10cm × 10cm). Measure the actual flying surface including ailerons. Exclude fuselage area between wing roots.

WING LOADING REFERENCE
| WING LOADING (g/dm²) | FLIGHT STYLE | CHARACTERISTICS |
|---|---|---|
| < 20 | Slow flyer / foamie | Very slow, floaty. Indoor or calm conditions only. Sensitive to wind. |
| 20–30 | Trainer | Gentle, self-righting tendency. Ideal for learning. Survives light wind. |
| 30–50 | Sport flyer | Responsive, handles moderate wind. Good all-rounder. |
| 50–75 | Aerobatic / warbird | Fast, needs good throttle management. Precision control required. |
| 75–100 | High performance | Fast landing speed. Experienced pilots only. |
| > 100 | Pylon / jet | Very high speed. Minimal margin for error. Expert level. |
THRUST-TO-WEIGHT GUIDE
| T:W RATIO | FLIGHT TYPE | NOTES |
|---|---|---|
| 0.5:1 – 0.7:1 | Glider / efficient cruiser | Cannot hover. Long glide. Motor for gaining altitude only. |
| 0.7:1 – 1.0:1 | Trainer / sport | Adequate for level flight and moderate climbs. Cannot hover. |
| 1.0:1 – 1.3:1 | Sport / scale | Good vertical performance. Comfortable margins for most flying. |
| 1.3:1 – 1.8:1 | Aerobatic | Vertical climbs, loops, rolls with ease. Preferred for 3D-capable planes. |
| > 2.0:1 | 3D / extreme aerobatic | Can hover, waterfall, harrier. High power demand. Expert only. |
