i just got my x8g last weekend, and this is my first ever quad. then i tried it indoor, just flying 2 feet just to check if its working then i accidentally push the throttle up and it some how crashed to a wall, then 2 right rotor is facing the floor and somehow prevented them from rotating and one of the blade also got twisted, i replaced the blade with one of the reserved and calibrated the rotor as well but when i tried to fly it again it seems that the right side is not lifting anymore and sometimes one of the rotor in the right will suddenly stop so i interchange the rotor ( ccw rotor to ccw rotor and cw to cw rotor) thinking that i broke the rotor but im having the same result. I called the store where i got the quad and they told me that the board could be the reason. Any idea what happen to my quad. Thanks in advance.

 
I cant watch the video on my slow phone internet service but if when the quad crashed and you didnt maybe turn the throttle off ,its possible a mosfet could have been burned out.

You said you calibrated the "rotor"?..Im assuming you re-calibrated and not just re binded the radio..there is a difference there.

Either a burned up motor, burned out mosfet or not a proper re calibration...Also be sure you installed the proper prop when you replaced it.

EDIT: Being able to see in the video "pic" it appears all motors are turning..i would say you maybe installed the wrong prop for the right side of the quad ....find the spare prop that matches the left front prop and install that one.

Bad choice for a first quad and bad quad to fly inside. Crashing is a fact of life when starting out. A lightweight inexpesive quad can take a lot more abuse than what you bought.

Look at the LCD on your radio and make sure all the trims are centered, then calibrate again.

thanks for the reply , i already removed all the prop, now how will i know if its fot the right and left prop? and what is a mosfet, is it the main board inside the quad?

The mosfet is part of the control board..if that is in fact bad its best to just replace the board...The motor wouldnt spin at all if it was bad...I cant watch the video so, do all the motors spin?

You have to determine what direction the left front motor spins in...The props are designed for either clock wise or counter clock wise direction.

Using this pic, you can see how the pitch or curve of the blade should look on the left front...Also based on this pic the left front does in fact spin clock wise...The same blade that goes on the left front goes on the right rear..then the other 2 props can go on the other arms..doesn't matter if its front or back.

wow, i should have tried that first, i think as i've said one of the prop got a little twisted then i replaced it but instead replacing it with prop B1, i replaced it with a2, i just realize that when i check the all the prop left inside the box, could that be the only reason why is it acting like that? the thing is, the store where i bought suggested that i should just ship it back to them so they can check it and i wont get it back until next week.

Have you put the correct rotor blade on?
Check you haven't bent the mainshaft (I did) as this will prevent rotor spinning fast enought.
