Modeled after the popular ultra-micro Blade® mSR heli, the Blade® mSR S is a great way to step up from coaxial helis and multirotor drones to a single-rotor machine. Fixed-pitch, flybarless rotor simplicity lets you enjoy extra speed and agility with a durable and efficient design. The included 1S 150mAh battery has a higher 45C discharge rate, so you get more responsive power while keeping the battery weight the same. Exclusive SAFE® and AS3X® technology helps keep you in control by delivering the stability you need to develop confidence quickly. The variable high and low rate modes allow each flight to match your flying style and environment. Even experienced single-rotor pilots will find the mSR S great to have around whenever the time, place or weather keeps you from flying a bigger heli.
