Raad,
First of all, welcome to RCU!
It may not have been what you wanted to hear, but you need a TRAINER in some shape or form. See the sticky at the top of the beginner forum [link=http://www.rcuniverse.com/forum/m_4537845/tm.htm]HERE[/link] and pick one out. There really is no getting around this. If you want to be successful, this is where you must start.
Yes, trainers may be expensive (some such as the Tower Trainer aren't), but its not because they are trying to take advantage of beginners like you

. Trainers are generally "built tough to last long" and some have special features to make it easier to fly. Cheap trainers ARE available if you look. Buying a kit will be MUCH cheaper, but it requires a lot more assembly on your part. IMHO, since you seem concerned with price, I would take a look at the [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCXF4**&P=ML]RTF Tower Trainer[/link]. Unless you buy a kit, and the cheapest components possible, this is probably as cheap as you're going to get.
One more thing, in your previous post, you state: "..i would not want that [crashing] to happen to me! and that is one reason i am worred about buying a plane over 150 dollars !! " The thing is, if you DON'T buy a trainer, you can almost be guaranteed that this WILL happen to you. Sorry, but its just one of the unfortunate realities of this hobby. Trust us on this one.
Good luck, and welcome to the addiction!
