New Youtube Videos, AE 0.1cc Diesel Engine

Monday, November 13th, 2017

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.

OS FS-120SII Gas Glow Conversion

Tuesday, August 11th, 2015

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 […]

There was a CD-260 […]

Just quick update.

Wednesday, January 11th, 2012

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 […]

CMEA Model Engine Show 2011

Tuesday, September 27th, 2011

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.

Updated FS-48 setup.

Tuesday, September 20th, 2011

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 […]

IHobbyExpo 2010

Thursday, October 21st, 2010

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 […]

Summer is Here.

Tuesday, June 22nd, 2010

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 […]

Some Updates

Wednesday, November 11th, 2009

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 […]

NAMES Expo and Other News

Monday, April 20th, 2009

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 is here.

Tuesday, December 30th, 2008

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 […]

New Engines at I Hobby Expo

Thursday, October 16th, 2008

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 […]

FS-52 Spark Runs Great!

Wednesday, October 15th, 2008

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 […]

FS-52 Spark Ignition Photos

Saturday, October 4th, 2008

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 […]

A Little House Cleaning

Friday, September 5th, 2008

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.


Tuesday, September 2nd, 2008

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 […]

Machines and Ideas

Thursday, May 1st, 2008

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 […]

Some News

Tuesday, January 22nd, 2008

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 […]

More FS-91 Surpass Diesel Conversion

Wednesday, October 3rd, 2007

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 […]

FS-91 Update

Monday, September 17th, 2007

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 […]
