>From what I know (which is almost nothing) the simple answer is: Carefully.
I had a neighbour who built model aircraft for a hobby, and would produce a top notch aeroplane each winter. Having built a 12ft wingspan monster (with radio controlled parachutist), he built a helicopter, which took 18 months rather than the usual 4-6 months. On the first test flight he got it 6 inches off the ground and knew he would crash it very soon, so sold it without ever flying it again. A quote I once heard: "A helicopter is not an aircraft, it is ten thousand spare parts flying in close formation."
