Even during the busiest times of my life I have endeavored to maintain some
form of model building activity. This site has been created to help me chronicle
my journey through a lifelong involvement in model aviation, which
all began in Mayo, MD

Here is a unique concept called the "Gravity
Plane" that theoretically can take off, climb to altitude, cruise, descend, and
land using only stored helium and built-in air compressors. Conceived of by Robert
D. Hunt of Hunt Aviation†, it
purports to be entirely self-powered, but in reality we know that conservation of
energy requires that 100% efficiency be realized in order for that to be so. Still,
it is an interesting idea. There are currently automated, unmanned submarines that
employ a similar principle for bobbing up and down through the oceans to collect
While there are lots of technical hurdles to overcome, it is an approach to "clean"
flight that should be explored further, if for no other reason than to rule it out
as a possibility. Maybe this would make a good radio controlled modeling project
for someone. I'd do it, but just don't have the time. Come to think of it, there
might be some stimulus money out there for funding such a green concept.
