Flying high while keeping the cost low---JSTOL


Introduction of the company

With a decade of continuous improvement, JSTOL keeps pushing the boundary of paramotor equipments’ cost performance ratio.

JSTOL, based in Beijing, China, developed its first UAV (unmanned aerial vehicle) engine in 2006, and since then has been making remarkable innovations and technology breakthroughs in the field of ultralight aircraft engine. The year of 2017 will be an important milestone for JSTOL, as it  is expanding from professional applications into mass applications, with the vision to bring professional quality products to the mass market at a lower cost.

Focusing on the customized research, design and production of ultralight aircraft engines, JSTOL has been making steady and rapid development in the general aviation products sector, including UAV products, paramotors, various light aircraft engines, etc. At the same time, based on its advanced technology in ultralight engine, JSTOL has also made great progress in other applications, such as ultralight portable pumps, power surfboards, agricultural light pumps, etc. With strong competitive advantage in technology (owning several independent intellectual property rights in R&D and applications), JSTOL is a high-growth high-tech company in general aviation.

In the meantime, JSTOL also reduces the cost of aircraft engine mass application to the lowest historical level through integrating the value chain across production and sales & marketing. JSTOL reduces the marketing and product support cost through social media marketing and big data analysis, and is dedicated to produce the most reliable products with perfect customer experience in technical support, purchasing process, services and product usage.

With the big momentum of China’s “One Belt, One Road” economic development plan, JSTOL will expand its oversea market in 2017, gradually entering the general aircraft engine business and mass application market of North America, South America, Middle East, Southeast Asia, Northern Europe, and Australia. JSTOL will start the globalization era of its products with the most competitive and cost-effective JSTOL-75 Paramotor.


J-75 paramotor suite’s curb weight: 18.5 kg:

The whole machine is exquisite and small in size. All the equipment parts after disassembly can be put in a simple air pull rod box. The weight is only 18.5 kg. It is highly cost effective, endowed with quick after-sales service, timely and rapid spare parts supply.

The ergonomic features:

There is thickening sponge filling behind the seat bag, which ensures the passengers to sit comfortably after taking off. The low hanging point configuration adequately address the “arm holding high” condition of the traditional high hanging point while controlling the handle, which makes the flying experience more comfortable. With the left and right side of rocker arm, the crescent man-machine engineering design is more suitable to the human skeleton and forms an integral whole with the aviator.


The technical features:

J-75 products use advanced CNC process framework to create finely crafted beauty, which is to be reckoned as a great leap. The perfection of the resulting visual effect can easily conquer the most critical eye from any constellation. (Even the Virgo will admire this masterpiece a lot.) JSTOL not only satisfies the recreational flight, but also at the same time, is more suitable for gliding assistance and extreme cross-country flight.

The mechanical properties:

The two main hanging belts of the J-75 product are respectively connected with the left and right rocker arm by hooks, which make all the weight scatter into two rocker arms. For example, the maximum load weight while taking-off is up to 100 kg (excluding umbrella head). Each rocker arm shares only 50 kg, with the front part bearing about 35 kg, the back part about 15 kg. The rocker's cross section area is greater than the main hook, which ensures the user to use enjoyably and safely.  

 The controllability:

There is another innovation in the design of the J-75. Besides through traditional handle to control direction, the low hanging point frame is more available to change the two rocker arms relative angles by making use of the unilateral leg stress to change the center of gravity. This can assist to swerve and achieve more advanced and refined control movement experience. Even if one takes pictures casually, the machine can be fully controlled and realized the flexible and precise rotation. 

The experience feeling:

J-75 is the paramotor suite product of fully independent intellectual property rights. It is no doubt the most cost effective set of machine, specially designed for light body weight pilots by JSTOL. On the world’s flying stage, JSTOL-75 will be a revolutionary product, making its users to achieve the ultimate enjoyment and spiritual experience.
