I unplug mine from the charger, hold it with a 2 finger grip, throttle up to hover (full up on a fresh battery is *not hovering*, and just hit the trim button until it stops spinning. The trim changes with battery power, but that's it. Once mine are set, it's good for the entire flight.
I have (well.. had) 5. Got them on sale @ Target for $9.99/each.
The key is just tiny little corrections, and adding side stick if you increase or decrease power from the hover.
Also, always launch & recover by hand if possible. Takeoff & landing is where you do all the damage in my experience. So far I've only had 1 destroyed tail-rotor and 2 lost airframes (1 battery failure, 1 mid-air collision with an air hog hydro storm).
Neat toys. For forward momentum, instead of a toothpick, we've been using thumb tacks.
If you get really bored, take it outside with a few mile an hour wind. We got them to what we estimated to be about 80-100 feet before it lost signal. If you do this, bring it down gently, or just chop the throttle & floor it again (takes good timing or else shovel recovery). Then, pray your idiot friend doesn't fly directly through it with his hydro storm.
