How long ago did you make purchase,I would suggest returning it for another,if possible.Here is Meijiaxin (MJX) Website ----Link: http://www.mjxtoys.com/
try taking the body off of the skeleton and cleaning the rotor cylinder, might be dirty or have some carpet/hair fibers keeping the blades from running at full speed even if the battery is fully charged
I just got one for Christmas too. Had it flying for 10 seconds, and lost control. I have to work on my piloting skills! After that initial crash, I prepared for another take off and realized my lower rotor was not spinning. It turns out that the tiny vertical gear that powers the lower rotor gear fell off its axle. The axle is connected to the sensor that receives the signal from the throttle. Luckily, I found that tiny gear sitting inside the head of my helicopter. After spending 2 hours trying to place it back on the axle, I got it running again. The rotor was spinning again, but it wouldn't take off. I did some troubleshooting, adjusting the trim multiple times. Then the gear fell off again. I found it and noticed that I had damaged the plastic teeth from using my tweezers to reinstall it. You can go to Team-RC.com to buy a complete gear system for $6.95. You won't need to replace all of the gears, just the one that fell off, and it's always a good idea to have spare parts just in case.
Hi,
We are a family that bought one of your helicopters. We immediately had a problem, the top rotor stopped spinning after a crash. We found out that when the helicopter crashed I wasn't paying attention(I am 10 years old)and I was still pushing the throttle while it was on the top rotor. Big mistake,when I tried again it Didn't lift off the ground. We then put crazy glue in between the top rotor and the shaft and tried it again. It worked! Both rotors spun! Good luck!

1) Ensure you're fully charging. Indicator light on charging unit should NOT get brighter at all when you unplug the helicopter. If it does, then plug helicopter back into charger until light stays the same when you unplug. Note: If you're charging with a usb charger and are using a laptop or the front side data port on your desktop, these may take several hours to fully charge as they are usb 2.0 and do not carry the full 5 volt dc charge. Use powered usb (3.0) on back of desktop, or get a usb/ac adapter. Normal charge time approximately 1 hour. Go by the light, though. 2) Don't run them dead. As soon as you can no longer maintain altitude, land and turn off helicopter. Fully discharging a Li/Po battery (particularly when it's new) will cripple it's ability to hold a charge, and can ruin them.
I found your question while searching the web for parts for my son's new, broken Air Hawk II. I also found that there are a few different mini helis marketed as "Air Hawk", so I'm not sure that my answer will apply to your machine. Mine came in a box as shown here: http://www.toygalaxy.net/2chmirche.html
OUR problem, which might be your problem too, is that the cylindrical metal weights flew off the ends of the stabilizer bar at the top of the heli. First, one came off, which threw the heli out of balance, which caused a violent shaking that probably helped the other weight to fly off. Without the weights, the stabilizer can't do its job, and the heli sways. Our temporary fix was to cut two strips of duct tape, 3/4" x 1.5" each, and wrap one strip around the outer 3/4" of each end of the stabilizer bar. This made our heli fly almost as well as it did when brand new.
The heli pictured here is almost identical to ours, and has the same weights on the stabilizer bar - these photos show what our SB looked like before the weights flew off... http://www.dhgate.com/2ch-rc-helicopter-air-wolf-co-axle-rtf-palm/k-ff808081278edf340127988dde3b153d-0.html#todescription
Hope this helps... happy flying (we can wish, right?)
