Is your "elevator" stick trim set at mid point? If so, just move the trim in to you a couple clicks. This should stabilize it. Mine likes to sweep left upon liftoff. It will hover in ONE spot by it's self without input but not very long. If you have a good zero on the elevator stick, it will randomly want to move forward and backward, you just have to correct with the stick (while in hover). I've found that keeping the heli in as small an area possible (2ft x 2ft) and not going higher than 2ft up is difficult (I'm new at this), but not impossible. Note: move anything that you might run into (obstructions) before you can set it down, out of the flying area. It will get away from you and just land it as quickly and gently as you can (broke a couple tail booms by landing too hard). All your trims should be centered if you are set up right. I had a hang of a time adjusting the servo link adjustments to achieve zero on all trims.
