Helicopters: Wheelvs vs Skis

When the H-34 Choctaw came out in Vietnam, it often sank into the ground. This happened when helicopters landed on malleable surfaces and all its weight was focused on three points (the landing wheels). To resolve this, later helicopters were designed with skis. That way the weight is more distributed on both sides.

So. my question is. Why do helicopters have wheels again? Is it because they are not as heavy as older helicopters? Or modern helipads made out of harder materials.

this is an army navy thing in this country. think about trying to move a helicopter with skids on the deck of a ship. the skids for the army choppers arnt so bad.

in some cases yes, but imagine trying to pull a helicopter with skids around the hanger of a ship, even with the optional wheel trucks you still have to lift it.

And a Chinook would look pants with skids. In fact skids are limited to the smaller end of the size bracket, and thinking about it there aren't that many military helicopters that still use them (thinking British Army Lynx/Bell 2xx, 4xx, Cobra series and other smallish helis...)
