Sorry, do you mean you are physically stuck in Auto Hover or you want to land without it? If the latter then:
 
A bleed flare is the best way to reduce speed and not gain too much altitude. Dslyexci has a good video on it, check out his art of flight series, specifically the one about stages of landing.
 
Basically though, try to incorporate holding down collective with a little bit of nose up pitch (use them together), this will slow the helicopter down and the opposite effects of down collective and pitching up will keep your helicopter nice and level (if balanced correctly). 
If you need to descend and slow at the same time, just lower the amount you pitch up (bear in mind it won't slow you down as quickly though).
A lot of the pilots on the public servers fly right to the LZ and pitch up/engage Auto Hover to slow down leaving themselves vulnerable to being shot down high over an AO. This obviously makes people angry (rightly so IMO).
You should perform the bleed flare far enough out so that you can slow yourself down and set yourself up for a nice, smooth landing without gaining too much altitude. After some practice you can even use the rudder to kill off excess speed on the final stage of landing and touch down at an angle like a badass!
 
Try to keep away from Auto Hover as much as possible for landing (especially when coming in at speed).
 
I would add that TrackIR is a fantastic peripheral for any would be pilot in ArmA.

For me, i will just get the, 'No Message Received for 'x' seconds'. As said, a dc and re-connect fixes the issue. It doesn't really bother me, i was just letting lexota know that he isn't the only one!
