Domestic NDAA-compliant 10-inch folding tri-blade — drop-in for the Gemfan 1051F-3. Made in Nevada, USA.
Folding propellers are multi-part assemblies — individually molded blades on a hub with pivot hardware — so blades are the replaceable consumable, and blade sets are weight-matched. No performance numbers are published until backed by test data.
Dimensions and fitment data are the referenced propeller's own published specification, not Anvil measurements.
If your bill of materials calls out Gemfan 1051F-3 — or an equivalent Gemfan folding-class 10-inch tri-blade — the Anvil Propulsion 10×5.1×3 is the domestic, NDAA-compliant replacement. Send us the foreign part number on your BOM and we'll confirm fitment.
| Anvil Part Number | Size | Drop-In For | Class |

Why replace it at all? Foreign-made propellers face tightening NDAA covered-country flow-downs and FCC restrictions. See our plain-language compliance guide and why the sourcing gap exists now.
