Thanks for the tips.

I checked the main rotor baldes and they were unbalanced, i added a little wight in one of the blades to get them balanced. I tried to fly it again, but this time i took it higer and it is easier to fly that below one feet from the ground....

I´m still getting used to the controls for the heli, i´m not able to maintain a statis hover but i know that with practice i will be able to do it... The heli flyes a little bit better now....

Thanks...
