Plus, if you just go from nothing to full, the model will leap into the air and disappear upwards at a great rate of knots - out of sight in three seconds! (and splattered in four!)
If the throttle 'curve' works like most heli's - the first half of the throttle movement just gives rotor rpm's, but the bird doesn't lift. The second half of the movement is where the lift comes in - but the rev's don't increase much - so go really easy as you increase.
If it all goes wrong, DO NOT panic and shut the throttle! (Fixed-wing flyer reflex!) Heli's glide like dropped bricks!
if you are calm and collected when all about you are going berserk - you've missed something important!

For a couple of days, a full lipo won't hurt, but if it is going to be weeks - - - then run it down to storage charge.
The easiest way of doing that is in the heli - hold the fuz and run the rotor motor as fast as you can - wary of chopping your face off with the blades!
-
Flying indoors is tricky. In an empty hall is ok, but in a typical house room, with furnishings etc, not so, because the obstacles all affect the downdraft vortices from the heli, pushing it around in unexpected directions!
Then, as you will find, if you get too high, it seems to stick to the ceiling, until you have throttled down to the point where it falls, and then it might hit the floor before you can rev up again!

p.s. Near flat calm here, but raining steadily!

It is the extreme sensitivity that is the driving force behind the need to get it to hover 'hands off'. It even has a fixed height auto hover facility Then it is just a case of the tiniest touch to make it move in any direction secure in the knowledge you can let go and if it has the space it will return to a safe hover all by itself.
To 'fly' in the conventional sense you have to master the control of yaw as well as pitch and roll. The effect these functions differ considerably as the speed builds up. To make matters worse its auto stability functions will override your inputs if they are too extreme.
In fact it could be said that it is a classic case of the worst type of model to learn to fly helicopters on!
Have fun!
ps
If you had fully charged the LiPo but only ran it a for minute or so I would certainly run it 'in hand' for a further minute before putting it away. Small LiPo tend to be more robust than big ones so as long as it is 'a bit' discharged it will be safe enough to leave. If you can organise suitable leads then a 'proper' LiPo charger could take in down to a true storage level.

I've just about got the hang of turning about it's axis using the tail roter and gently moving it forwards and backwards, just got to wait for a calm day and get it outside.

I think you will find even the calmest day has more than the warm air currents in the house.
About the only advantage is there will be more space to drift about in!

Bought a spare battery for it yesterday £7.99 from my local model shop, 2 quid cheaper than anywhere else and I got staff discount on top..happy days!

If you put either - turbulence - or - air movement - after has more, the sentence makes more sense!
