Th3re There is a small 4ch helli you can get from amazon that is super easy to fly out of the box and it can take a beating. Look for the wl toys mini 4 ch; its lime $40 and it comes with a 2.4gig radio which is very nice as well. Parts are cheaper than dirt too. Have fun.

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/

Hi,

Does it power up and the main rotors spin? If you have no power it could be a faulty battery.

Kind regards, Julian

Under the mower,the blade is held by a single nut.Unplug the spark plug.Lift the mower.You will need to hold the blade.I use a large screw driver to keep the blade from turning as you remove the nut.Do NOT but a blade before you get the old one off.Some blades use a star shaped hole others use a round one.You need to know which you need,as one will not fit on the other.Once the nut is off the blade will come off too.Then just put the new blade on and the nut.

ok this is what you got to do you have to take apart the helicopter and in it try to turn the bottom blade you will hear a clicking sound from there you should see whats wrong i had the same problem hope this helps

Hi. This is called "talk" its when the helicopter starts spinning instead of the blades, remote control helicopters and real ones.To stop this from happening you need to make sure the tail Rotor is going correctly OR probely the best thing to do would be take it back to the shop and get a hole new one.

Syma DragonFly 9093 or 9083 rc heli... has the same exact size tail blade... just put one on myself... works fine..
