dave the gyro has no effect on the cyclic axis' which is what is being used to keep the heli level when inverted.
That said with the advent of modern heading loc gyro's, the tail will stay where you put it & is unaffected by torque reaction.
Incidently the model actually hovers better upside as there is no body to upset the airflow...... thats if you can get your head around left being
right, up being down etc.
This is by far the hardest part of learning to fly a model heli. At least in the real thing, the controls are always the same!!

I thought the function of the gyro was to stabilize the fuselage Paul,if the gyro has no effect on the cyclic axis (for,aft,left,right if i'm
correct understanding) why is the gyro in there than?

 If you fly upside down in a real heli and you pull the collective you will get closer to earth instead of getting away of it....i think

The gyro dampens torque effect of the rotors by altering the pitch of the rear rotor to suit.
I cant even get my copter to hover

Cita, the gyro only has an effect on the yaw axis.

avoid

I was an engineer - not a pilot, but we did tend to 'have a go' from time to time.....
first time i tried hovering was at about 25feet over a minefiled in Bosnia; concentrates the mind somewhat (BTW I was crap and the pilot had to snatch
control back )

I loved the way they could just hover about 1M off the ground and then taxi out to the runway at same height, was a joy to watch, Was trumped once
though, was working on a B&Q roof down in Yeovil, when a 'bird' appeared over the next roof, when straight over me at about 100ft then
went silent as it went away, later found out it was a cobra, Lovely

I understand Paul,i thought the gyro had some sort of limited function on the cyclic controle with an overrunning function to help a stable hover.
Have the RC helicopters a governor as well? (engine RPM-pitch)

Yes governers are used by some, but its only quite recently that they have become fit for the job. (speed ...digital servo's etc.)
