I don't have a problem in handling the King Air on the ground....corners well with differential power, brakes-it isn't exactly a 'small' or light aircraft...I know when I flew the RW King Airs back in the early 80's it was 'interesting' to get used to the taxi characteristics.
Now for something different-search on-line for a magazine devoted to King Airs-once in thier website poke around and you'll find a number of back issues you can read various articles on RW operation of the various King Air models-not a bad read....but you do have to poke around a bit to find the back issues, it is 'obvious'. (not sure on AVSIM's policy on posting links etc-sorry this is a bit Cryptic)
Oh, best part is the back issues are free to look at...
