RIP Stefan Gasparin

I was just informed by his family that Stefan Gasparin passed away. Stefan inspired many people with his amazing line of CO2 motors he produced. His was a friend, a master modeler and a great man. He will be missed!

He played a role in this hobby that many/most don't know about. Stefan is one of the reasons why we have what we have now. He never stopped innovating. I did not know him personally, but have worked with him on a few projects. It's sad to see the great Gasparin go.

Another pioneer leaving us, some details on his life:
I was born in the year 1937. I come from Slovakia. In 1961 I graduated from University of Technology in Bratislava, branch of communication technology.

Until 1991 I worked in the Research Institute of Mechanization and Automation as Head of the Laboratory for Research and Development of Ultrasonic Generators and Oscillating systems for Industrial Use.

I was an active model builder and I organized model builders' events. I was working on miniaturization of radio control systems for small models. This has led me to CO2 motors.

In 1972 I constructed my first CO2 motor, and CO2 motors started to fascinate me. Until 1990 I was constructing CO2 motors on an individual basis or in a small number.

In 1990 I started to cooperate with Mikrotechna Holešovice, which was operating as a manufacturer of aircraft onboard instrumentation. This cooperation continues through my affiliated company GMOT which manufactures my CO2 motors.

Since 1991 I have been dealing with CO2 motors on a professional basis, I was implementing their series production on a step-by-step basis. I have designed and put in production about 60 types of CO2 motors in a wide range of configurations.

Since the year 1992 I have lived and worked in the Czech Republic, in Ricany some 11 km from Prague center. I manufacture my CO2 motors in the workshop which is a part of our house. My family and professional skills of my external coworkers help me with this work.

In recent years I have been working especially in the area of electrical drives of small models.

I am very glad that my work on perfection and promotion of CO2 motors was awarded Oleg Antonov Diploma which is awarded to one person in a single year by the International Aircraft Federation (FAI).

Meeting with Wm. L. Brown, Father of today's CO2 motors
on the occasion of his 80th birthday in the year 1991.

What a shock to read this first thing in the morning. I have attended many OpenScale events over the years in the Czech Republic. One of the reasons I went was because Stefan would be there. The highlight of the weekend for me was the sitting in the hotel restaurant the night before the competition waiting to see what Stefan would produce for "show and tell. " I was never disappointed.

He was always very approachable and glad to help anytime I had a question or needed something. Everything he produced was of the highest quality. He will be missed.

WHAT??? Another of the greats of the modeling world passes away!! I am so sorry to hear it. As I myself grow older and see these great people who played a exploratory role in the model aviation role come to then end of their life,I only wish that there's a younger person out there who will fill these emptying spaces of these fantastic people.
Thank Joe for informing us of this one great person.

Stefan Gasparin was a leading light in the Czech tradition of precision and excellence in all things, including aeromodelling. I remember years ago reading an article in the old Aeromodeller where disbelief was expressed about reports of the long flight times of rubber-powered scale models in Czechoslovakia. Ah, more propaganda from behind the iron curtain! We know better now, and the Gasparin CO2 motors the epitomised the engineering skills of the Czechs. His little motors, silent, clean, ultra-reliable and micro were forerunners of the electric revolution that was to come. Smooth flying Stefan.

This is sad news. I remember working with Stefan on coreless motor gearboxes and going to Toys R Us to buy a bunch of 7mm Super Slicks motors to mail to him, which he then installed in gearboxes he made to accept them. Later when I was molding CF props I sent him a couple. He liked them and asked for a few more for his friends at Micro Invent, which I made. I suggested that his friends at Micro Invent should make CF props. They did, and I stopped making my own as theirs were so much nicer. Then Stefan began developing micro BL motors and came up with winds that were just right. And, the motors themselves were beautifully machined as was everything he did. I still have a few of his motors and always save them for projects that deserve them.

Stefan will be missed.

I was really sad to hear about Stefan today.

Through his ideas and innovations our models came to life.

I always think about the micro equipment creators while building a plane including Stefan. How they have helped us make our little creations be as good as they could possibly be. I will think of Stefan when I pull out one of his tiniest creations that I have been saving for a special plane. Hopefully to make an excellent flying machine that is worthy of one of his great innovations.

It was a pleasure to sell and use his motors.

Sorry to see a micro innovator pass

Stefan's spirit will live on in our models. I have a number of the motors and gearboxes he designed. What a pleasure it is work with a piece that was designed with focus on quality materials and workmanship. Designed to be serviceable rather than cheap.

I had the good fortune to build and fly a free flight model with a Gasparin CO2 motor over twenty years ago. I remember it well. The motor provided endless fascination. Sad to see him go.
