The Hobbs on my RV-4 just hit 200 hours today. It has been relatively trouble free since the first flight on March 12, 2007. The only squawks so far have been the right brake getting soft a couple of times requiring it to be bled (no leaks obvious). It still continues to do this even though I replaced all the O-rings in the master cylinder and the wheel cylinder. The only other problem has been a rough idle since the last condition inspection. I am not sure what I did to the spark plugs on cylinders 3 and 4 but they were not firing properly at idle speeds. Run up and mag check was great but anything less than 900 RPM had a miss-fire. On base leg and final the EGT low temperature alarm would illuminate for #3 and #4 at engine idle speed. Add a little power and the alarms would clear. Anyway, I changed out the plugs on those cylinders and life is good again.
Have I said how great this airplane is? I am still amazed at the handling and responsiveness of this airplane. Everytime I put her up, just before closing the hanger door, I have to turn back for one more look. I now know what an addiction is.
