First, make sure the center of gravity, CG, is correct; it should be shown on the data that came with it. You may have to shift the battery or tape a coin to one end for this.

Second, a common cause of this is to pull an aircraft up, instead of letting it take off by itself, and putting it into too steep a climb for it's speed, causing a stall.

Have you flown before? If not this is NOT the plane you can expect to succeed with. You stalled. A stalled plane is not controllable. You can't correct the problem. You can only prevent it from happening. Usually one wing stalls before the other, the plane rolls toward the stalled wing and does its buffalo turd imitation minus the smell.

Guys, this looks like little more than a cheap two-channel toy of the breed found in shopping malls and back-alley Internet shops. It lacks any form of control surfaces. I'd be surprised if it even included an instruction manual, much less any useful documentation.

Regardless of how well it's set up and regardless of pilot skill, the plane is probably no more airworthy than the package that it came in. Murad, your best course of action would most honestly be to get a better plane.

All those pilots that cry "interference/brown out" as they spiral into the ground and no amount of opposite aileron or up elevator will pull it out.

*3D planes are called that because they are specifically designed with obscenely large control surfaces, which in conjunction with prop wash from high thrust, low pitch propellers, allows the insane pilot to maintain control in a fully stalled condition.

These are specialized airframes in the hands of very skilled (but insane) pilots. Cheap toy grade wannabe jets need not apply. Your results may vary. Not good with any other offer. Cash value 1/1000. May be hazardous to children, pets or livestock.

I've read some of your posts from last year, and I'm sorry but there is no introduction to RC other than a real hobby grade plane like a Parkzone Super Cub or a proven heli like the DH9116 (Many have learned to hover with it), or similar coax.
It doesn't further your skills much if you keep buying the cheapest stuff with the brightest stickers giving a promise of easy flight.. It also sounds like you could use an instructor. Is there a chance you could get some help from an experienced pilot?

Yeah, my first plane was a Megatech Skyliner. I watched someone seemingly fly it quite well so I bought it. I couldn't fly it. I even found a VERY experienced pilot > he couldn't fly it. It was junk. Frankly the one you pictured looks even less capable.

Best bet, get a decent plane and start over unless you like the challenge (or headache).

After looking back through Murad's posting history, I get the impression that he's beyond help

Theres sometimes a huge gap with beginners between how they think a plane or heli should fly and how it actually does. For example, you see someone flying some advanced 3d plane or heli at a park, think 'I could do that' so go off and buy some random, cheap model, and then expect it to fly exactly like the one you saw at the park. Also, immediately expect you'll be able to fly your new model instantly, just because you saw the guy at the park and it looked easy, right?

Both expectations are completely unreasonable. The best thing you can do is find someone who already flies to give you some advice on what to buy, and preferably lessons.

Then again, there's the type that never listens to any advice, doesn't understand what's involved and blunders along trying to work it out for themselves, crashes a lot, gets frustrated, and then often, unfortunately, quits the hobby.

This type is solidly represented in practically every hobby known to man
