| FirstRC criteria-based suggestion | 10+ with adult supervision claimed stock speed ~20 mph; 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. |
