hi all I have just got a battery for my dragonfly I have changed it to li-po from the old ni-mh. First time I have been able to fly it so I got it just off the ground by a foot and it went mad like someone holding it and shacking it to death. Before I could shut it down blade strike both blades now have deep chunks out of them. I have a spare set ready to go on but just wondering if anyone had an idea what it could be to cause the mess. just seamed like it went un-ballanced.

I am not familiar with that specific model, but unbalance is usually associated with something loose or missing. Ensure all parts are there, to include flybar (which is a key component of balance in a coaxial heli) and double check to make sure all screws and bolts are tightened so no wobble from bad connections causes shaking.

ok so I have taken blades and rotor off and have found the horizontal bar for blades is bent looks like I have bought a crashed one. It is the walkera dragonfly 40 but cant find new bars anywhere. are they the same for the 36 or any other walkera.
