Every time we take a plane up we're taking a risk in my opinion. There's tons of things that can go wrong while in flight, too many to mention. If you're new to R/C flying and your plane is brand spanking new as well, I would get some help. Talk to some people who you know fly. I see you're in Egypt, not sure about hobby shops there, but surely get some help. An experienced pilot could look your plane over with a fine toothed comb and take it up for its first test flight, then maybe he/she could give you some lessons.

Good luck and be safe out there.
