I would highly suggest RADDS school of rotary flight.... and a SIMULATOR. You can do all the exercises in the simulator and be safe. Learn to fly helicopters that are properly set up in the simulator and you will know when your real helicopter is not setup correctly. Most of all you need to learn the four orientations and have it down cold before flying in the real world.
There is a lot of information on the net about this subject... google is your friend.
Gees, I just looked at your helicopter... that is not a big bird nor is it collective pitch. It is very gentle and easy to fly as a counter rotating blades are.
