I think a lot of people that don't know machining or engineering wouldn't have any idea how much effort it takes to make something like this. Especially with how amazing it ran! They always say you can tell just how good a motor is by how it sounds and how smooth it runs... And usually engines on the smaller side (especially 4-stroke) can be a little finicky. When I was in my junior year of tech school i made a single cylinder pneumatic motor that had a small generator rigged up to it, I wired it to a small maglite light bulb and that was about it. It took a good bit of machining and I had to get the tolerances pretty tight but it was an awesome project! It's almost 30 years old into this day you can still start it right up and it purrs like a kitten! Even the original maglite bulb still works

[@MakerB]

I truly agree with your comment. It sometimes breaks my heart when people talk about this build as if it's not a big deal. Of course, I made it for people's fun, but on the other hand, I don't want people to take it too lightly. In particular, some people ignore gasoline engines as old technology, but I hope they think about the basis for today's new technology. I respect your past achievements and wish you all the best in the future.

i just came back from my 3rd semester at machine school, i made a 4 cylinder radial pneumatic engine, it turns pretty good unfortunately the vaulve system we used was not designed for that engine and it is quite primitive, so the first time i tried to run it, it made the crankshaft uneven, so now it dosent run as smooth as before, i shouldreaally just disassemble it and straighten everything out.

[@garymaclean6903]

I spent my youth and early adult years competing in racing control-line model airplanes that had 2.5 cc engines. (FAI Class F2C - Team Race) There were many aspects of the sport/hobby that were required in order to be successful, from a light but strong model, to a high performing quality motor. As nothing competitive was available off the shelf at hobby stores, everything was hand made, from the model, to in some cases the motors itself. We had a highly skilled machinist who for several years made the motors from scratch, while in other years we relied on motor specialists who had mini mass production runs, and made their motors available for sale to some competitors. Motor technology was continuously refined and performance improved and the motors became more capable. My brothers and I raced planes with diesel (compression ignition) two stroke motors that had to fly in 100-lap qualifying heats, and 200-lap finals. There were strict limitations on plane dimensions, including fuel tank size. Essentially our plane had to fly at about 125+ mph for at least 33-laps on 7-cc of fuel, then make a pit-stop to refuel. A really good 100-lap heat race time including two pit stops is in the low 3-minute range. A successful racing engine is all about metallurgy and precise tolerances. We bought some Russian-made motors which were consistently winning at the time, and our machinist couldn't figure out how they made the pistons, which are critical to success. It appeared to be some sort of sintered blend of aluminum that was high in silicon. As our racing motors were always run lean to get the most range, they ran very hot, so the science behind pistons was in how to control thermal expansion at high temperatures so the engines didn't seize while running hot, yet expanded at the same rate as the cooler cylinder to maintain compression, while being hard enough to show little wear after many races running with low percentages of lubricant in the fuel. Cylinders were typically chrome-coated and had a very slight taper so that when pistons were lapped to fit they were 'tight' at the top of compression, yet ran 'a little loose' through the rest of the bore to minimize friction. We had to learn a lot about everything from aerodynamics; construction and design techniques; materials science; combustion and fuel science; to competition strategy. We were lucky to receive 'free samples' of new high-strength materials, such as just developed Kevlar and Carbon fibre, from companies like Dupont, and fuel additives from Shell, who were willing to support our efforts. We we lucky enough to qualify on the Canadian team about 6 times to compete at the FAI Control-Line World Championships in Europe in the 1970's, 80's and 90's. It was a great learning experience and an opportunity to travel and represent our country in a highly competitive and technical event. A quick search on KZbin of - FAI Class F2C - Team Race - will show what the racing is about.
