For vertical take-off and landing (VTOL) SkyProwler 2 transforms by folding out its arms. When transitioning to fixed wing flight it folds these arms in to reduce air drag. SkyProwler’s 4K camera is 3D stabilized. Use the drop door for deliveries. Remove the wings, and you have a high performance quadcopter with thruster. You get two UAVs for the price of one.
