RE: Eagle 50... breaking in or broke
You see a heli was always want to stay left and right. Helicopter itself is a very unstable flying machine and consently need correction to maintain stabality. So as a pilot you need to be quick and control the heli and not the heli controlling you. For example, If you have a basketball spinning on the tip of your finger, can the basketball stay still on the tip of your finger? Sooner or later the basketball will fall left or right. This same principle applies to heli as well. That's why I always don't recommend my customer jumping into a 6 ch heli as their first heli. It's like learning to run before you even know how to walk.
I suggest you put this heli aside because it's too much for you for now. You should start with 4 ch coxial heli first and gain some flight time and hovering time. Any 4ch coxial would be nice to start with.
