Mode 1: Easy one-key ascent. Landing is also done with the same one-key operation. Very stable with a 6-axis gyro. The body is under 100 grams, so you can fly it anywhere, within regulations. It's for indoor use, but you can fly it outside in light wind. It's a very beautiful aircraft; you'll be mesmerized just looking at it. Please enjoy! • Scale body that reproduces exhaust ducts and molds in detail. • Flight time of about 10 minutes or more with 2 rotor blades. • Easy hovering with automatic altitude hold function using a pressure sensor. • Easy takeoff and landing with one-key operation. • One-touch detachable modular battery. ◎ We have adjusted and confirmed the operation before listing. Please make fine adjustments in a spacious room at first. ◎ Please remove the battery slowly. ◎ The horizontal stabilizer is not attached; please use adhesive. ※ We also have other micro-helicopters for sale; please take a look.
