Welcome to Wattflyer.
Well, where to begin? First thing with those Airhogs, They are infra-red controlled, so if you're using them in a very bright area, that can cause problems for the control signals. So keep it somewhere without bright sunlight or other bright light sources.
As far as the spinning, all I can say is what I think is already in the instructions troubleshooting guides. Make sure the tail rotor spins free. It can have some fuzz or hair in it, picked up from the a carpet or whatever.
As far as not taking off at all, there could be numerous reasons. Could be the bad signal like I mentioned before. Could be a binding issue like the tail rotor thing I mentioned also. And it could be the helicopter battery is bad. I think it charges from the transmitter batteries? Maybe the xmttr batts are weak? Also, I think those things use lipo batteries, so if you over-discharge them once, they're toast. If you've kept trying to fly it when it already ran out of power, it's likely you ruined the battery. And I don't think you can replace the batteries in those like a hobby quality micro heli.
Good luck with it. If you're looking to get more serious into the RC hobby, poke around here, and you'll plenty of advice for a more easy to fly and repair heli.
