"Ten year plan for radios and paint"??? The 430 was put into my plane in 1999; the paint was already several years old. Radio continues to work well after discounted early WAAS upgrade right after I bought her in 2007. I am continuing to get compliments on the paint job.
It is easy to get obscenely high hourly costs, just add up every penny you spend and divide by hours flown. Apparently Stinker and I think alike, where the hourly cost to fly is the expenses used to fly, which does not include the costs to own [hangar, annual, insurance, pitot static testing, GPS subscriptions, etc.]. To get the hourly costs many people here have, you've got to be including avionic upgrades [optional, nice to have], ANR headsets, Foreflight subscriptions, multiple ipads to run Foreflight, etc.--too much discretional spending not required to operate the airplane. Maybe there should be three categories: operational [what it costs to fly]; ownership [the fixed costs]; and the Goodies [things you get because you want them]. I bet the latter would be the largest number for many of my fellow MSers . . .
