About the landing gear, if you hav the training gear on, move the balls so they are only about 2" away from the skids. Then clip the remainder off.. I notice that my HB gets some nasty vibrations if I have the long stems on there. Once I cliped them, it runs very stable. You will encounter some GE until about 1ft off the ground as mentioned in the previouse posting. Just make sure everything is ballanced and having your blades tightend correctly makes a HUGE difference!!
