Recommended for beginners: tools worth starting with before you dive deeper into CG, wing loading and typical setup mistakes.
Center of Gravity Visualizer
Enter components, masses and positions to get the CG in mm and as % MAC, with a clear visual.
→Wing Loading Calculator
Compute wing loading in g/dm² (and oz/ft²) with a plain-language interpretation.
→Model Behaviour Diagnostic
Pick symptoms (dives, stalls, spirals…) and get a list of likely causes and a checklist.
→Setup & balance
Tools for setting the center of gravity, balance and basic model geometry.
