Well i am new to the Cx2 . Im getting it to fly pretty well and able to get it to hover. Several blades, a flybar, and an inner shaft later, its getting there.. Just wondering if anyone out there can suggest some good upgrades for the cx2 that would be great... Im just looking for something a little more.... It also seems like it doesnt want to stay at the same altitude for to long.... Any suggestions would be great..... THANKS
