I have a B gearbox now. It was mentioned above that I'd be happier with a C gearbox.
Could you elaborate?
Mike

It has to do with the inertial mass of the prop. 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.
