The Engine is the key. Flying cars are ready. A flying car may not look like you think. It is a small light weight wing platform with light weight powerful engines that lift the craft. The wing pad or platform provides safe landing with engine out. These have been mission capable since 2008. I am just warming up the M31128 explosive resonator motors on my Scooty Pup Jr. The Scooty pup Jr. is available in 49% kit form for $1999.00. No oil to change. No tires to go flat. No traffic you cant go around. Runs on propane until someone comes up with something better. The two piece body has a foam core for flotation and is light weight. Can be used on land, snow and water. Without fuel and battery one man can carry or easily pull it into lift off position. These have no wheels as they were not intended to be driven on the road. With a 4 foot diameter folded/on models with folding wings/ and weight of 60 pounds empty the Scooty Pup can take off on the patch of road in front of your house.You can take off and land in a parking lot and pilot yourself into a parking space just like you do in a car. The Explosive Resonator motor that I discovered, developed and fabricated is fuel efficient, light weight, has no moving parts, will not wear out, and is inexpensive. The Explosive Resonator is superior to the pulse jet it resembles. The Explosive Resonator was invented by me because there were no small jets available that were suitable for use in personal flying machines. I tried many motors and propellers counter rotating and not and the pulse jets that I built from whatever plans and information I could find. I tested pulse jets, many designs and sizes. One thing they all had in common was that they all got white hot, used a lot of fuel and didn't give off much thrust. They were completely unsuitable for flying machines for my purpose. One thing they had in common was that when you start a pulse jet the first pulse is an explosion and rocks the motor. After that the it starts running. the running part is lame. What I wanted was to find a design that repeated that initial explosion at a fast rate. I knew that it would at least be more powerful. The Explosive Resonator was discovered by repeating experiments over and over, changing sizes and shapes. Trying anything to get results that pointed the way to a better operating cycle. So while retesting the pulse jet design from the beginning to see if I had missed something I cut off the tailpipe of a small pulse jet and tested it before I was to weld on a different tail pipe. The pulse jet that was left was only about a foot long but for the first time a motor exhibited the string of explosions that I had wanted. The thrust was greater than any previous motor type tested, it did not get hot, and it did this without much fuel.
