 I had the same experienced with my CX2. If you are using the charger that came with the kit, I would suggest buying a proper charger system. I bought the Ripmax, sigma EQ. This gives a good charge and balances the cells.  I also agree, if the batteries are cold or are charged in the cold then they will take a long time to charge. you need to keep them at room temperature. I would also advise that you buy a 12v battery to charge at the field or on the day. The battery will drop its charge slighjtly from one day to the next.   technology its a wonderfull thing Gordon

Hi Gemma Yes, I have experienced the same problem. If you are using the charger that came with the CX2, I would suggest buying a proper charger system. I bought the Ripmax, sigma EQ. This gives a good charge and balances the cells.     Safe flying Gordon

  Hi ,  You have to remember that flying a heli is all about balance. You need to set up the correct trim via the swash plate to start with. I use both E flight and Flight power batteries. As the flight power battery is slightly longer than E flight, this can be used to change the C of G.   As they say 'it all hangs in the balance'   Kind regards Gordon

  I have a blade cx2, I have noticed that the status indicator on the 4 in 1 unit is changing from green to red when I am trying to increase power to the motors. I believe I know the problem but there is no info in the manual. I have new motors in the post. I hope that might solve the problem. Can any one help? Thanks to the Lads for their information on the Batteries.
