This project is not fiction, is based on the same technology we use in larger rocket helicopters and Rocket Belts technology and this will be used to produce the "Libelula" a portable helicopter easier and safer to fly.
The best of this technology is that this type of helicopter don´t need a tail rotor because they have no torque, the impulse is directly to the tip of the blade rotor so this don't produce any counter rotational reaction and a small rudder is all you need to steer, being the simplest form of Helicopter and the safest because 86% of helicopter accidents are due to tail rotor failure in most cases fatal in addition to this, its flight is much more stable.
Using modern aerospace materials like carbon fiber, Kevlar, titanium and aluminum can reduce the weight and it can be lighter than the Magill Pinwheel helicopter that show very nice performance, stability and safety and this is a fact because the three prototypes from Magill still are intact at Swiss Copter showing that none was damaged in any accident.
There are two options for the rotor of this helicopter, a fixed rotor is very simple and can be flown kinesthetically or varying the rotating disk and another option is with a collective pitch rotor controlled by the left hand .
If you are a helicopter engineer or you know about helicopter rotor design, ideas are accepted for the rotor head of this helicopter.
History of the Backpack Helicopter
For decades many people tried to build the smallest helicopter of the "backpack" type.
The idea is not new, in the 40's an Austrian named Paul Baumgartl tried to do it but the lack of an engine very small, lightweight, powerful and reliable made this idea was abandoned. He was subsequently tried by several others without success because they used two-stroke engines because they are very powerful and light but nothing reliable.

Eugene M. Gluhareff
In the 60's came Eugene Gluhareff with an idea of jet engines mounted on the tip of the rotor blade and he built his first version of the MEG-1X which had a single blade and a counterweight on the other side, this design proved to be very stable.
Later he decided to use two blades and larger engines and the MEG-2X was built.
This version was able to fly but the problem was that this engines had to be very light in thickness to save weight and they operate at extreme temperature, in fact they glow orange when they work so it was too heavy and centrifugal force and high temperature caused them to deform and in one test the tail of one of the jets flew away.

I built a Gluhareff jet engine when he was 19 years old from plans and because of the affection that Mr. Gluhareff took me, he gave me the distribution in Mexico for the Gluhareff jet engines and test stands. Later on a trip to Gardena California I met Mr. Gluhareff personally and it was there where I had contact with these prototypes of helicopters. His idea was perfect, only that their engines were too heavy for this application.

This is the G8-2-40 valve less pulse jet engine made by Juan Manuel Lozano Gallegos at 19 years of age, this engine runs on liquid propane and produces 40 pounds of thrust.
I still have this engine.

The World's First Rocket Helicopter
In 1954 an American inventor named Gilbert W. Magill of Glendale California designed and built the HR-1, a "mini" portable helicopter, at the tip of the rotor blades a hydrogen peroxide rocket engine impulse the rotor, this helicopter was better known as the "Pinwheel".
Magill made his helicopter portable in a carrying box which was a success that flew incredibly well and had a fantastic performance for its size, with a maximum speed of 161 km / h (100 mph), a ceiling of 4570 meters (14.993 feet) and a range of 32 km (20 miles) with two tanks with a total of 20 liters of hydrogen peroxide 90% ea
This small helicopter still holds the world´s record speed of vertical climb rate.

Later Magill built the second version by contract with the U.S. Navy's with larger peroxide tanks and a tripod landing gear that could take off standing on legs, this is the model flown in this video.
