Props
Nothing special about the props and overhaul or repair. One thing to note is that on the P model the front prop was increased to 78 inch diameter from the original 76 inch. The rear prop stayed 76 inch. The reasoning behind this change was to achieve the same single engine rate of climb for both engines. The rear was a little better on single than the front so Cessna's cure was increase the diameter of the prop 2 inches on the front to equal the rear in single engine rate of climb. Unfortunately it really put the prop close to the ground and picking up FOD from the front to send it back to the rear prop increased. There are techniques to avoid this problem.
