Guyz its my first plane plz help.
and i dnt understand what would have gone wrong, things were working perfectly.
i gave full throttle and throwed the plane forward and pulled the elevator stick down.
But it dint fly instead it got banged on the ground.
Motor not working properly giving strokes.
plz help     

Why would you do that ? push the stick down ?

1, Please fly a lot of simulators and read

2. Read this thread

Also check your elevator orientation it should be opposite to stick movement, moving the elevator stick down on the radio causes elevator control surface on the plane to move up and vice versa

is CG required for skysurfer v3 ? if yes then hpw to do tht some1 plz give me step by step procedure .. 

CG is usually not a major concern in these planes as long as you fly with regular 3S 2200mah LiPo.

Giving full elevator seems to be the real issue behind it. You need to give very less elevator in order for the plane to clear able to climb.
Full Elevator = the plane will get into nose up attitude and then will dip down straight for the ground.

If the plane is straightaway dipping down then either you have the elevator channel reversed or you are giving elevator input in the wrong direction.
Check if the elevator control surface is moving as per Shahil's suggestion.

Irrespective of whether you're able to sort out the issue or not, You would still need Simulator practice before anything else.
Stop further damaging your plane, Invest in a Sim

Please do read the RC India Gems! You have joined last month, and made 11 posts, but obviously have not seen/noticed/read or given due cognizance to the basic tenets of the Forum

Sims are all very well, but a correct build is paramount. Why try alone? Join up with like-minded people and have fun together; also learn the ropes

May be moter's one of the wire become loose or would have broken.

My friends had crashed and same problem had come. you just solder them again and it will work perfectly.

We fly near GB road on Sat.. you can join us..

To help you better post a short video, moving all the controls and throttle.

 Guyzz i have seen videos of skysurfer , when model is kept on surface  & throttle is given the model moves in forward direction slowly..
but mine goes in circular motion.
what would be the problem ?
plz check the pics of ma prop i think it is little bend.
 it is stock .. no damage on prop occured yet .
i asked Rcbazaar for this thing they told it is correct as it is right thrust.
is it correct ?   

shaft is bent?

or the whole motor is in sideways?

I think the motor is off the mount.

Is the motor shaking or is it tight?

ok so whats the solution ? should i change the mount setting >?
i think the motor is in sideways lilttle bit  

Motor is tight

Was the motor moved after the crash?

Nope it was the same as before when i saw in the store at Rcbazaar ..
i asked them about this bend motor they told it is correct it is "Right Thrust" some logic is behind that thing. 

that may need some "Right Thrust" but not sure needed this much.

Buddy

Only advice i would give you is to get in touch with an aeromodeller in you locality, to get this skysurfer in air. However i would advice you that you immediately do the following

1. It is easiest to spend couple of thousands and buy a model, but difficult to put it up in the air, it is not like some car that you buy and start running. therefore you need the skill set to fly and knowledge to put a model together

2. Do fly simulators a lot,

3. Hang around in this forum, use search function and read, dont look for quickie solutions, there is none

Well, the problem your model runs in circles is because your whole motor is tilted side ways, I don't think the motor shaft is bent, check your motor mounts.
Now your motor is providing a Little yaw motion to your model because of it's tilted position, once you correct it, everything should be fine.
