I received one last week. Flew it only three times so far. Very stable and responsive in intermediate mode. I'm having a hard time with elevation. Any movement and it drops in altitude and then I over compensate. I keep going up and down, up and down. Just need more time with it.
Unlike the previous model I have, the RC Eye One S, this one is larger, has LED lights on the front and sides to aid in orientation from a distance, has altitude hold, and a larger battery. Also three flight modes. The beginner mode is slow and sluggish, the intermediate mode is much more responsive, and the expert mode is ridiculous, at least for me...I'm a rookie. It will dart like a bullet from a gun...smoking fast... no help from the gyro.
