| Manufacturer's stated age | not found on retailer listings checked; check box/manual |
| FirstRC criteria-based suggestion | 10+ with adult supervision claimed stock speed ~35 mph; manufacturer-claimed speed-limit/training mode (-2 yrs, floor 10 for fast non-crawlers); LiPo battery: adult should handle charging/storage [FirstRC criteria, not manufacturer guidance]. This is our rule of thumb from published specs, not a safety rating. The manufacturer's age on the box always wins. How we calculate it. |
