V1 Cuts with the Auto FX is a non event at any weight. V1 Cuts with flaps 17 and max weight, without the auto feather are a bit more interesting. The A/C does not fly untill you get the prop feathered. Sea level single engine climb rates are greater than 1000fpm. Mmo is .48 Vne is 248, Vso is 88. Only certified up to 25K, the pressurization is weak. Holds seal level to just over 12K. It is much more stable than the smaller King airs, and would be an easy transition for any king air pilot. If you've got any specific questions, please feel free to ask.
