This is video footage of the maiden flight of the electric Crossbow. This ship was built from a production mold using production plans and instructions. This ship is "stock" in every way and then some... The motor used is an inexpensive $18.95 Suppo BL-2217/7. The battery: An inexpensive ($15?) 1300mah 25C 3-S LiPo battery. Prop used is a folding 9X5. (Performance using these components speak for themselves. Plenty of room for larger motors and larger battery packs with the intent to carry a 1900mah-2200mah high output pack.)
All up weight is 29.6oz flying at a wing loading of 11.8 oz/sq ft.
