Personally I've had to dive on the front of a B206 skid to prevent it toppling off the back of the truck. Wheels don't have that prob.
Wheels are easier to forget to select down. A guy in OZ even managed to cancel the 200ft warning before removing the aerials on the underside. Twice.
Skids bend. Once someone lands on uneven terrain or with the aircraft weight in the middle of the skid there is a really good chance it will stay bent in the middle. This generates stress and stress makes cracks and cracks make....
It also appears that the result of uneven load distribution through a skid would stress the airframe.
Another thought.
Why has no-one designed a manually retractable skid gear for a light turbine? Something to fold away and clean up the drag.
Race ya to the patent shop...
