The 2s35 is a custom 3D-printed FPV drone frame designed around the longevity and accessibility of Li-ion 18650 batteries. Perfect for long-range cruising, cinematic flights, or park flying, this frame features a clever, integrated commercial battery tray that makes swapping packs as fast and easy as a traditional LiPo—no more tedious battery straps or loose cells.
