Reasoning
Across sources, the product is consistently described as Ready-To-Fly (RTF) with kit packaging. The PyroDrone listing heavily uses 'RTF Kit' and related terms, aligning with the product’s naming, while the manufacturer site also shows variants but the explicit RTF/RTF Kit labeling appears most representative for this SKU. Although some evidence on the manufacturer site references BNF, the explicit, widely-used packaging term for this product is RTF Kit, making it the most accurate single canonical value.
