I bought my first heli (Dragonfly Micro) and I am having trouble with the set-up. I have balanced the blades and trimmed the controls(to my newby abilities). The main rotor still causes it to shake until about 1/3 throttle making it hard to lift off. It also leans to the side and drifts around out of control once I leave the ground making a hover impossible. I believe this is due to the unstability of the air close to the ground. What tips do you have that might help me get off the ground.
