Heli-Max 230Si Ready-to-Fly Quadcopter w/2.4GHz Radio, LiPo Battery & Charger Performance for Every Quad Pilot This is a Heli-Max 230Si Ready-to-Fly Quadcopter. Pilots looking for something bigger than "palm-sized", but at a lower cost than 350-size machines, now have the perfect option. Like larger models, the ready-to-fly 230Si quad offers more stability, easier visibility, and better ability to handle outdoor flying conditions. With sophisticated intelligent technology also built-in, the 230Si gives first-time flyers outstanding odds for success. It's a satisfying choice for seasoned pilots, too. Altitude Control Management: Offers three modes - auto-hover, maximum 10 feet altitude or manual control. In auto-hover, press a button and the 230Si holds your selected altitude. Actual Direction Control: Turn it on and the 230Si goes in the same direction that you move the sticks, whether it's flying toward you or away from you. Return To Pilot: Brings the 230Si back to its pilot automatically. Simply push a transmitter button. Built-in sensors call the model "home." TAGs-FX Sensor Fusion Technology: TAGS-FX continuously keeps you in complete control. Sensor Fusion Technology integrates data received from dual sources - a 3-axis gyro and 3-axis accelerometer - and compensates immediately for any actions except those you command. TAGS-FX corrects unwanted movement in yaw, pitch and roll while also preventing drift in any direction. You're more in control than ever before! Beginner and Expert Flight Modes: Select Beginner or Expert flight modes from the transmitter. In Beginner mode, releasing the sticks lets the 230Si stabilize itself in flight - perfect when you're unsure of how to react. Expert mode turns off the TAGS-FX accelerometers, allowing greater maneuverability. Choose the mode that's right for you. New pilots enjoy unprecedented confiden
