The 150 and 100 share the same FSECU, the 200 has an improved version. The flex shafts, brakes and actuators on the 200 slat/flap system are a weak point on that aircraft as well. I don't fly them, I just fix them. YMMV:ok:

Hot rod?
 

I doubt the hotrod status of the G150. Same MMO, less ROC, more range because it carries 2000 pounds more fuel. G150 is, on average, a LOT more expensive to purchase.

Less of a hot rod than a G100 for sure. The Mmo is 0.875 on the G100 and 0.85 on the G150.

Are you Aerocardal?

The G150 has the best speed/range/cabin in its class. The G100 is definitely the best "bang for the buck" if the narrower cabin isn't a problem.

The Slats do not create an issue if an operator isn't abusing them. If one is planning speed properly, there's no need to extend them at their 250 limitation all of the time. My rule is less than 220. If I can't manage speed better than that, then I should be doing something else.
