i recently purchased a 6-channel dragonfly#35 and wasnt aware of the ammount of skill it took to operate one of these. my excitement quickly turned int frustration when i couldnt get my helicopter off the ground and after ruining 2 sets of rotors im afraid to damage it any further. im not familar with helicopter lingo so u have to bear with me, there is a strange grinding sound comming from one part under the gyro and when my throttle is maxed out my helicopter just tips over, plus my battery only lasts for 2min. max, i have no idea how the settings on the gyro or the transmitter should be set and my servo bellcrank doesnt move anymore. any help would be greatly appreciated. thanks.
