The "B" is limited to 3000 kg/cm^2, the "C" can take twice that much. It means you can run a Warp Drive prop, pretty much the heaviest on the market. You also have a better choice of gear ratios, IMHO. I have run a 2.62 and a 4.00 with a 582. The 2.62 was on an "X", the 4.00 on my "C". The "X" needed the standard rudder trim tab (see the Kolb drawing, attached), my "C" needs a trim tab less than half the size and with barely any deflection (less than 5 degrees) My neighbors also comment that the "X" was much louder and since the only difference was the gear ratio (I ran the same prop on both aircraft to test the difference between the gearbox ratios) and there was no difference in performance except that my "C" was almost 80 lb lighter with commensurate better climb.
