I can appreciate where you're coming from because I understand that you're limited in pursuing something that you have a passion for. Were in your situation, I'm quite certain that I'd want more out of my P3S as well, and would likely search for ways to accomplish that, although probably not to the lengths that you have. Fortunately, I've been blessed in that I have access to some rural farmlands for flying. I'm also blessed in that I have a P3S that gets some amazing range without the need for any mods. For the record, my Standard can routinely get 6000 - 7000' before RTH kicks in. My personal best range was a bit over 9200' last summer, all without any mods, windsurfers, or boosters. This was all done over rural or isolated lands with little if any population, although with wooded or forested areas. I do have a P4 that performs very nicely but, my P3S will always be very special to me. All of that aside, I do understand your drive to do more with what you have and I wish you well in your quest.
