I guess you know this, but an APM multi-rotor is sopposed to achieve a stable hover at 50% throttle. If your quad hovers above (or below) 50% throttle you need to decrease (or increase) the 'throttle_mid' parameter. Don't change the throttle curve on your transmitter.

Try this, if you haven't already:

Using pitch and roll curves makes the quad less sensitive around the middle stick position. This helps while landing or trying to get a stable hover.

Thanks @swapnil. Yes...I had read about the stable hover at 50% throttle level. But before this I have mostly flown RTF quads which had good throttle response much below 50%(say around 30%) . In fact in some of those quads when the throttle reached 50-60% and still the quad was only hovering, it meant that battery had almost depleted. That's why, when in this quad I have to go to 50% for stable hover, I feel uneasy Anyway, I did not know that throttle_mid parameter could adjust this property. I Will try that out.
