So, how does one fly a Gyro?
Very similar to 3-axis. Stick and rudder control - without the flaps part. :D
Is it difficult?
No, flying is very easy, coming back is the difficult part.

Once in the air, and trimmed, it almost flies itself. Not succeptable to turbulance and wind. Can handle almost anything weather can throw at it. I've seen a gyro flying, and landing in 35 knot wind. Handles like a motorbike in the air, turns very tight, can come quickly to a standstill, put it in a nose dive, recovers quickly ........ :D ....

........ :D ...

:D

. Great fun
Do you consider it more dangerous than a trike?
Do not have any trike experience, but from what I've seen, read, and experienced in a gyro, my 2c. On the ground, take-off and landing, if you stick to the rules -
no. In the air, much safer than a trike because of the bad weather handling characteristics. 99 % of accidents and incidents in a gyro is during take-off and landing.
How small an area can you land in?
Experienced pilots will land it in your back yard, zero ground roll. Unfortunately it must have an approach, cannot land with a vertical approach, unless with a stiff headwind. Student pilots land it with about 5 - 10 meter roll.
How small an area for take off?
As trikes and planes, take-off depends totally on weight, weather, wind and height ASL. We fly at 5300 ft ASL, 2 up and take-off roll is 150-200m.
At sea level I understand take-off to be 50m.
Can you hover?
Yes,
but you lose height. It can hover, and retains it height in a stiff headwind - 30 knts or so - seen a video of it even flying backwards.
Looks fantastic!
For normal salary earning mortals the most fun you can have in the air -
my opinion.
