Also a major reason why you see that is because most micro RTF heli's are fixed pitched. And like I also have Blade CP, it does have collective pitch in the main rotor blades but the torque from the little tail motor can cause instability due to slow reaction from the gyro to the response of the motor timing. There is a delay from the time you idle up to the time it takes for the tail motor to increase or decrease in speed. The motor just isn't fast enough to keep up with the duration of the ccpm main rotor blades because of it's fixed tail rotor. During rapid pitches it's impossible to stay completely stable. The Blade is however a neat little heli. You can't beat the price for what it is, but I just don't think that the 4 in 1 electronic box was a good idea.
