No skin off my nose one way or another. I just sold my avid in four days on barnstormers and realistically I think you could probably sell a 1500lb rated kitfox easily as well. my experience with selling my plane leads me to believe there are alot of guys in the SP range looking for light and inexpensive planes. I have never been ramp checked (yet) but would assume that FAA will not be dragging around scales to see if you are sitting at 1320 or 1420. Maybe checking your papers etc (which by the way if you are a sport pilot and flying a plane rated at 1500lb would get you in trouble). Do what you want and if you are already a PP than it is no big deal anyway until you get so old that you cannot retain your medical.

There in lies the crux. I will be registering at 1320#. I have tens of thousands of dollars invested not to mention the time involved in building it. I have decades left to fly this thing. I do not wish to be the guy in 15-20 years who has to give up his flying because he wanted to fly their plane with an extra 200#. Maybe working in the healthcare industry has got me a bit jaded. It may not be that prevalent that people come down with ailments that ground them but I would rather keep the odds to a minimum for my own sanity. I have dreamed of doing this since I was 20 so it is damn important to me to be able to fly into my golden years.
