Bell skids
Hi Tip,
with the low skids itīs easier to land, because you have more ground cushion and its cooler, to do low flying, only three feet of the ground ;-)
With the high skids, you have less danger while doing rotorrunning passengers changes - and more possibilities to do outside landings without endangering the belly.
Unfortunately the C/G is higher with high skids - so you have to be careful doing autorotations.
