How do I know if my Hartzell Prop Gov is Compatible with a Hartell Aerobatic Prop?
I'm rebuilding my IO-540 C4B5 for my DR-109 (2 place aerobatic) . My engine came from a Piper Aztec,with Hartzell Prop Gov Model F-2-86. How can I figure out if my prop gov will work with a Hartzell aerobatic prop - like the one off an S-2B? thanks! check
Propeller Governor for IO-540 C4B5
Thanks to Bob and Wes for their replies - my dilemma of determining if my stock IO-540 governor from use on a Piper Aztec would work with an aerobatic prop. I went to TIFFINAIRE inc and had tech discussions with their rep Gary Bibler. The F2-86 gov I have can be converted to the -59Z governor used with compact counterweigthed aerobatic props. The governors all use similar and acceptable cores. What remains is whether my Aztec prop governor is airworthy - worth using as a core for the rebuild and mod work. I never realized how expensive prop governors are - cost ranks right up there with anRS5A fuel servo! thanks again for your help. marky
