Just replaced my MT P-860-4 with the HZ 320/360 from Vans (Hartzell p/n S-1-10). One difference I found is that the Hartzell governor will not make the Hartzell prop go to coarse pitch at idle power whereas the prop would go coarse with the MT even with the engine producing no power (windmilling, ignition off and mixture at idle cutoff).
I liked this feature of the MT as going coarse significantly increases the glide if the engine fails but is still windmilling.
I replaced the MT as it was due for it's 6 year overhaul (the Hartzell has no calendar TBO) as this would save money in the long run but I am now seriously considering getting the MT overhauled and reinstalling it.
Thoughts, comments??
