The Ready-to-fly Dromida® Sync™ 251 UAV makes it easy to fly your own quadcopter, inside or outdoors. By taking advantage of simple-to-use but advanced stabilizing features, the Sync 251 helps keep your flight under control automatically!
Optical Flow technology gives the Sync 251 UAV unrivaled stability in an entry-level quad. Optical Flow gathers data from patterns on the ground or floor below. It uses that information to assist the quad in holding its lateral, or side-to-side, position. Another feature, Altitude Hold, automatically adjusts the throttle to maintain your desired flying height. It all adds up to easy takeoffs, confident landings, and rock-solid flight even in light winds.
Can piloting the Sync 251 UAV be any simpler? Yes, when you select its optional Headless Mode. With Headless Mode active, it doesn’t matter which end of the quad is the “front” — it will always move in the same direction that you move the control sticks. You don’t even have to think about orientation!
The 250mm Sync 251 UAV has a high-contrast, black and white trim scheme that makes the quadcopter easy to follow in the sky. LED indicators below the prop arms add visual flair and an additional point of reference for orientation.
