Just curious.
My second hobby is Radio-controlled aircraft. Of course, the fast ones...:devil:
I would have a hell of a healthier bank account.

The jet engines for the models are self-starting and the smallest ones make about 12 lbs. of thrust and go for about $2K. The bad boys make 30-40 lbs. thrust and go for about $3,500. Not uncommon to have a 2 engine jet have $10K up in the air. Not a cheap hobby. But they easily exceed 200 mph true airspeed, and they sound fantastic at speed!Radio controlled airplanes/helicopters.
Several months ago, I pulled into a residential street here and was confronted by a F16 taxiing in the middle of the road heading towards me! Actually it was a model RC airplane. The fuselage was something like 3 or 4 feet. It stopped and it made a U turn. I followed it until I came to a man holding the RC transmitter. I had rolled my window down, when following the airplane, but the expected chain saw engine like sound from a 2 cycle gas engine was absent. When the owner stopped the airplane near him I could hear a rrrrrrrr sound. I pulled up and stopped. I yelled and asked it it was an electric fan (ducted fan) engine. No he shouted back and said it was a turbo jet!! and about the same time I smelled the kerosene fumes. Impressive.
It was only later, I realized that was a sophisticated model airplane...it had made a U turn! It had nosewheel steering.
I used to build model planes as a teenager up until I went to college.
I got interested in cars in college, and as a proud Triumph TR3 owner I started learning how to repair cars. The TR3 had a major breakdown of some sorts every 6 months, minor problems between, and I had almost no money.
Learning how to repair cars lead to modding cars. If I get my 70 finished, I could well find myself buying a model airplane.
When I want good super-glues, some specialty paints, etc, I go to a "profession" model RC airplane/helicopoter/car store near where I live. By professional, I mean, these things aren't toys for children. They are expensive for adults.

Thanks for that video posting. Just amazing, particularly to stationary hovering towards the end a few feet above the run-way. You'd think an airplane could not hover like that without thrust vectoring since there would be no airflow of significance across the flight control surfaces. That hovering at single digit foot altitudes was dangerous..one mistake and a lot of money would go down the drain.
I replayed the video and noticed he didn't do any truly stationary hovering at the beginning, the plane was probably too fuel heavy at that point.
That is affirmative. The larger jets carry in excess of 1 gallon of kerosene, and the extra weight (sometimes the tank location) hinder the power to weight ratio/center of gravity. There are several models that use true thrust vectoring, but a lot of work to pull it off. I'll post up some prop planes doing high-alpha and hovering maneuvers. Truly amazing skills required. I am only just starting to accomplish this.Radio controlled airplanes/helicopters.

This one is electric....I'll let Gene guess the amps/watts the C-50 motors consume. The rolling circles are Very hard to do, this guy makes it look easy. Just think about the visual coordination required with elevator and rudder controls reversing every 180* of rotation.
