Stixoz:

All advices above are very good.

Think positive and try to stay ahead of the reactions of the model.

It is very possible that you will loose control of the model, or simply, make a mistake that will damage the thing; just make a mental note of it and accept it as a simple fact related to the hobby, which is not the end of the World.

Now, much more important than a damaged model is safety!
Respect the propeller and the destructive capacity of your model when flying at high speed or with the engine spinning that knife.
Keep your hands away from the propeller at all times!
Learn to kill the engine using the throttle trim, as an automatic reaction at the point you feel you have totally lost the control.
That will reduce the damages of a crash or the hurting of other people or properties around.

Just be ready to feel uncomfortable, nervous and dangerous during the first flights.
After those first flights, you will be very happy of the step you are ready to take.

Congratulations and the best luck!
