The AE0.1 video continues to be popular. I made a couple new videos about this engine. First a look inside the engines to see just how small the parts are. I also made a Solidworks model where it’s easier to see some of the design features.
I had an OS FS-120SII I was going to run with ignition and gasoline. I found a suitable Walbro carb, but it needed a few parts to mount to the engine. Details can be found here OS FS-120SII Gas Glow Conversion. There is also a video of machining one of the parts required on a […]
Browsing some sites with photos from the Nuremberg Toy Fair this past weekend a few new engines popped up. Browsing some sites with photos form the Nuremberg Toy Fair this past weekend a few new engines popped up. Weston UK was displaying a few new or prototype offerings from RCV Engines. There was a CD-260 […]
I’m working on several new pages to add to the projects page. I have not been idle, but progress has been slower than expected. There’s a high speed milling spindle, cnc lathe, a sad end to the cox project, and some other engine info. I hope to get the site refreshed in the next week […]
This past weekend I made a stop over at the Chicago Model Engineers Association’s annual show. This is a small group and that makes it fun to visit because it’s not crowded and you can talk without being rushed. I did not forget the memory for the camera this year.
Last year I posted a video of the FS-48 at the flying field. I have installed a Robart fueling valve and Cline fuel regulator. The fuel regulator improves consistency of mixture setting for the large 13 oz on-board tank. The valve allows starting and warm up with an auxiliary fuel tank containing standard model diesel […]
The IHobbyExpo show has certainly changed since I first attended 15 years ago. The economy and the internet have reduced the number of exhibitors and visitors. New products are often found on the internet before the show. Still, some manufacturers manage to keep a few things quiet. On to the good stuff. OS Engines will […]
I see it’s been a long time since I’ve posted. I’ve been busy with a new baby boy and several projects on top of work. I did manage to attend the NAMES event this year. It was interesting as usual, but I didn’t get any photos this year. I visited with a friend and did […]
I’ve been adding some videos to the How To page. I hope to add more as time is available. A Saito rebuild is next on the list. A few new engine manuals have been uploaded to the Download page. I have more to scan and upload in the near future. I am considering offer several […]
I visited the NAMES Expo this weekend. I managed only a few photos. I was preoccupied with observing the various engine designs. In other news, I’ve had a few inquiries about the bearing puller. I’ve been busy with work recently but will make up several for sale. Please contact me for […]
Winter has overtaken Chicagoland in a big way. It’s unusual to experience this much snow and cold, then get a rainstorm and warm temps to wash away almost all of the 10+” of snow on the ground. There were even tornado watches. So as winter makes it hard to fly much, I’ve been working on […]
I went to the I Hobby Expo today. I didn’t have a lot of time, but managed to find a few new engines. Great Planes was showing the new O.S. Engines FSa-72, the newest in the Alpha Series. Please excuse the poor angle in the photo. Saito was showing the already announced FG-20. The second […]
I’ve flown the FS-52 with spark ignition with methanol fuel. The fuel was 8% Klotz Original Techniplate and balance methanol. After test running the engine with this fuel at home, I checked for oil under the rocker cover. There was plenty. I’m convinced the crankcase ventilation system works as it should and draws oil through […]
I’ve added photos of the FS-52 spark conversion. I haven’t flown it yet, but expect to run and fly the engine in a few days. I expect it to run well. I have learned that the RCEXL ignition will operate well past 8,000 RPM and the 10,000-11,000 RPM I expect to run at will be […]
I added several items to the Swapmeet page. Several engines excess to my needs right now and a list of engine parts I have available for sale or trade. There are many Enya fourstroke parts, many O.S. parts, and a few Saito parts.
I’ve been able to get some flying time in this summer. I put a few hours on an Enya 46-4C II with spark ignition. It has a CH Ignitions system installed. I bought it online at auction. It’s old, there was a note written in the box, “Run 6-28-88.” It uses the mechanical timing advance […]
I’m short on time right now, but am in the process of replacing my lathe with something a little more stout. I’m also searching for some tooling. In the mean time I’ve decided to do some testing with E85 fuels and glow ignition. It seems some have had good luck running E85. Running E85 with […]
As winter grips Chicagoland I’m not able to do much testing of engines. It’s R&D season. I’ve added a few books to my library and found some good information. There will be new ideas to test in the spring. New fuel mixes and new designs. I am thinking about a major update to the main […]
I continue to work on the FS-91 conversion. I think that the carb for this size engine is becoming the sticking point. The acceptable air/fuel mixture range is rather narrow and the model carbs lack the proper tuning. Since model diesel fuel, especially without ether, approaches air/fuel ratios of gasoline I decided to try a […]
After making a new “lanova” cell I attempted to run the engine. It started and ran but was not happy. I sleeved the throat of the carb, but this did not improve things significantly I was able to get about 6500RPM out of it. The carb needles were very hard to adjust and it wouldn’t […]
