So you want to learn to fly that helicopter you have just bought, well first it needs checking out, the radio needs to
be checked against the model to make sure all controls respond to the correct servo's.
It is also wise to check all nuts and bolts on the model that may have become loose, especially the servo screws.
Check the servos operate in the correct way and have not been accidentally reversed.
Members will help you with this but as said before it is a hands on approach for you.
