Hi! I recently bought a DJI Phantom from an overseas online store and received it earlier this week. I was able to assemble the DJI Phantom and everything checked out ok except that the Phantom unit is unable to take of the ground despite putting it at full throttle. I have done the following: 1) Charged my Phantom battery 2) Ensured that the Propellers are correctly installed with correct clockwise and anti-clockwise rotation as per manual. When I read the manual and the DJI online FAQ (http://www.dji.com/faq/phantom-faq/), I came across this... I then proceeded to install the DJI Assistance Software and was able to do the IMU calibration as described above. However, this still does not solve the problem. Below is a video I made tonight to show you guys what I meant. https://www.youtube.com/watch?v=a6JumrNy2GI Please advise as I have failed to find similar experience from others and the solution to the problem. Thanks.
