So I have run glow engines for many years but only recently began to acquire and learn how to operate the compression ignition engines. So as my interest grew I began to understand why I never had these engines, FUEL. No just because the compression ignition engine is also referred to as a diesel, that does not mean that you can use fuel from a gas station.

Typically diesel airplane fuel consists of the following ingredients, ether, kerosene, and castor oil. Often times a cetane booster is also used. Those readers that live in the US know that obtaining ether is nearly impossible do to federal laws. There are very few other sources for pre-mised diesel airplane fuel, Davis Diesel sold exclusively through Tower Hobbies and Dr. Diesel,

Well Tower is currently waiting on a resupply of Davis Diesel fuel. I have read and contacted several members on this forum that are much more expert than I am in these engines and specifically mixing diesel fuel. Well seeing as my interest in these engines is growing and possibly only a passing thing, I did not want to make a huge investment in materials to make fuel. So here is what I did.

I went to O'Reilly auto parts and picked up a small 7 or 8oz can of Johnsen's premium starter fluid. The can says that it is 50% ether and the SDS sheet seems to confirm this. Now John Deere makes an 80% ether starting fluid but ordering a single can of that costs 3 times as much just for the shipping. Seeing as the auto parts store is a short walk from my work, I just picked this up.

In a graduated container I sprayed the entire contents of the starter fluid into it with a partially open lid to allow the propellant to escape. I was left with 6oz of LIQUID with a large percentage of this being ether. I next mixed 6 oz and Klotz castor oil and 6 oz of 1-K kerosene from Lowes.

To my great surprise this mixture worked exceptionally well. Take a look.

As the title says and I accept the risk. 99% of my deals have been very favorable and I feel lucky in that respect. However one of the last deals done here was not quite as expected. I will not name the RCG member but anyone with enough detective skills and interest should be able to determine who this is quite easily. I have purchased 3 things from this person over the last 3 or so years. Two of the 3 have been a dud. I am officially through dealing with this person. He either has no idea what he is selling, does not thoroughly inspect what is being sold, or plain just doesn't care.

Unresponsive to PM messages about this as well.

Time for some more comparison videos! This time it will be a series on 60 size 2 stroke engines. It seems the 60/61 two stroke engine is becoming more and more like the DoDo. Very few companies are making glow engines in the 60/61 size range anymore. OS only makes the 55AX and 65AX. Who knows if Enya really makes them anymore; I do see a 61 CXR listed but I have never seen one advertised. ASP/Magnum still make the 61A, but really that is about it.

So in the last few weeks I have been selling some engines to make room for a few 60/61 size ones. Granted many of the engines I have on hand now are somewhat dated, but they are representative of a finer time in the hobby. Here is the list in no particular order:

OS 61 FSR Special Edition
Irvine 61 MkII ABC
Mutunuc 61 Millennium Pro
Magnum XL61A
HB 61
HP 61 Gold Cup
OS 60 FP
K&B 61 ringed
Enya 60XF-III

These engines will be run and tuned prior to the actual run comparison videos. In the comparison each engine will be run with a 12x6 APC prop and Omega FAI fuel. Glow plugs will not be a constant. Each comparison video will consist of three randomly selected engines and they will be evaluated on max RPM, idle, and transition. A poll will be on each video so viewers/subscribers can vote on the favorite engine of each series. At the conclusion of round 1 the three engines with the most favorite votes will then go head to head. Votes can be based on ANYTHING the viewers like, not just the max RPM, etc. Sort of just a popularity vote and not necessarily a performance one.

Here is the first video in the series.

Over the past 2-3 years I have dedicated my hobby time, and considerable amount of money, to creating a glow engine video database. I chose to do this one day while searching YouTube for videos on a specific engine that I wanted to purchased and hear run. Well I was unable to find a single channel that had the following:
- wide range of engines
- consistent format
- quality videos
- disassembly/reassembly instructions
- how to videos.

That is when I decided to make my own video database. Now granted many of my first videos were pretty rough as I was learning filming techniques, editing, etc. But I would like to think my videos have evolved to be quite nice. One tab on my channel is titled playlists and here I attempt to organize the plethora of videos in to more logical groupings. By using the search feature present on every YouTube channel you can easy search for a specific engine as opposed to hours of searching through my channel. Stop by and take a look.

I have had my share of glow engines complete with the instruction manuals. I have never seen one quite like this before! I purchased this engine here on RCG for less than it was listed at; good thing since the engine was not complete. Now I have made a few videos of this engine and my Look Inside, not made public just yet. The only paperwork that came with this was a tips leaflet titled "Vmax Please Read This First!" This is the most honest, to the point, no holds barred printing I have ever seen. I LOVE this! Now I may have different feelings about the engine, but the writers of the instructions are spot on! I have attached the document for others to read.

Pay special attention to page 2, paragraph d, but the entire thing is worth reading. I cannot tell you how many times I have encountered this EXACT scenario at fields that I have flown at.

Now this particular engine is distributed from a place called Richmond RC, The website looks a bit ancient and I really cannot tell by visiting it if it is still operational. I did send them an email to test the validity of the site and store, but I have not received a response yet.

As I mentioned above. I did completely disassemble this engine to inspect and clean it. The folks have a much higher opinion of the engine than my inspection revealed. I have run the thing one time thus far and for a 52 sized 2 stroke, it is not that impressive really. The quality of the materials looks....well like typical Chinese made glow engines, marginal. The crankshaft is so odd that it looks to be designed to shear in a crash, or even a prop strike. I have never heard of nor seen one of these engines before so I am evaluating it based solely on this used example that I have .

This hobby has changed a LOT over the time I have been in it. The thing that strikes me however is how many people are flying quads these day. I have never flown or even been remotely interested in these things. I have never been a helicopter person at all either. My love is in glow engines of all shapes and sizes, and of course conventional airplanes. You know that ones that have these two aspects called TAKEOFF and LANDING. Obviously anything that flies has these two elements but I am referring to the type that takes up runway space.

Perhaps my view point of these damn quads is limited. I realize there is a tremendous and REAL market niche for these things in aerial surveillance, security, inspection, etc. But 95% of the folks flying these idiotic things are NOT doing it for the good of customers, to earn money, or keep things secure. So what are they doing? It seems that 95% have a camera of some sort on them so are these people just taking videos and pictures illicitly?

Looking through these blog posts on a weekly basis 90% are quad related. New products, this that, whatever. It is nice to see those seldom posts of folks still building airplanes out of wood and flying them with glow engines. Although I am not that old, I guess I take an old school approach to this hobby. Personally I think all of the quad flyers are and have been the biggest detriment to this hobby. Luckily now the FAA registration issue has past us by, but that really threatened this hobby for a while. All due to the idiotic people doing stupid stuff with these damn quads.

Long live GLOW engines and BALSA airplanes!

If you too are interested in glow engines as I am I have a YouTube channel devoted to this section of the hobby.

Rotary valve engines are somewhat of an oddity in the glow engine world. For whatever reason they really did not take off and few manufacturers ever made them. I have acquired several over the last few years and they are engines I will never part with. The first is a Webra T4 60 engine. As fate would have it this is the second one in a very short span that I have had my hands on. The first was a subscribers engine for runs and video making only. The second one featured here is now my own. A really awesome RCG member offered it to me as a trade. I gladly traded my Saito FA-180 for his Webra T4 60. Funny think is we both had very little, comparatively speaking, invested in these engines.

The second rotary valve engine is a bit more common. It is the HP 49VT. Originally manufactured in Austria by HP, it was bought out by the MECOA company. I am not sure if the current production units from MECOA, or ones manufactured under there ownership, still say Made in Austria on them or not. I would like to believe the one I have is a genuine Austrian made engine. I bought this engine over a year ago and it has been that long since I ran it last too. I hope to work this engine into the run cycle very soon. Better yet I would love to find an airplane that will allow me to switch between these two engines so they can both get some airtime. Let me add, this is the ONLY engine in my current collection that I have never disassembled or removed a single screw on also.

Here is...Continue Reading

My YouTube channel definitely has its benefits. I get to try out some really cool stuff that other modelers let me borrow. This post is on the very rare Webra T4 60 rotary valve, belt driven 4 stroke engine. A very awesome subscriber, Dan, is allowing me the opportunity to look his engine over and run it before he installs it in an airplane. Thank you Dan. There will be a total of 4 videos in this series but only the first 2 are posted at this time. Enjoy.

For an engine that had a very long production run, these are seldom seen on the used market. I believe that it was released around 1971 and I read that it had a run of over 40 years. So where are they? Just in peoples collection, never to be sold? Certain parts are still available on eBay, but no real critical ones like the apex seals. I have found mainly screws and drive washers. Why am I rambling on about this particular engine? Because I was fortunate enough to get one in a trade. It cost me a very nice Saito FA-91S which I thought was a fair trade. I mean I could list a wanted ad for a 91S and most likely have one in a week so I am not too concerned about replacing this engine.

As it turns out this is the first edition. The later models had some slight differences.

I was very glad that the fellow I was trading with gave me the opportunity to inspect this engine BEFORE I committed or mailed the 91S to him! Well within 3 minutes of opening the box and inspecting it, my 91S was packaged in the same shipping box and ready to go to a new owner. I was not planning on disassembling this classic but a closer inspection of the fasteners showed several things. First, it had been apart before and secondly some of the fasteners were in terrible shape. Heads completely stripped out on at least 5 of them. I made the decision to open her up after I placed an order some some of the few spare parts available, mainly screws, a rotor, and apex seal springs. As of...Continue Reading

Well I have been running glow engines for many years, but never a diesel. Well that has all changed now. I have much to learn regarding this type of power but I think I am getting the learning curve down to a better level. I had a very nice OS 40FP on hand that I had purchased from eBay over a year ago. I decided to try the MECOA diesel head as opposed to the Davis Diesel offerings for cost reasons. After purchasing all of the other items required, I set out to run it for the first time, video #2. I think this beats the hell out of all the damn quad videos in the Blog section. JMO

A very awesome fellow RC modeler sent me a Value Hobby Easy Stik 60. This makes the 3rd one I have had. The first two were lost due to crashes. The first being a 2.4GHz loss of bind failure and the second was an elevator control rod failure. Anyway, I am very excited about having another one of these airplanes as they are excellent fliers. A tremendous value for the money too. Please see my video playlist as I assemble this nice ARF.

First video is below. The remaining ones can be seen at this link,

Of four stroke engines you dirty minded people!! I recently scored two of the best deals in a long while. (Besides of course a free engine.) Although these were not free they were under $65 for the pair. Acquired separately from different parties in the last week. The Enya 46 looked to be in really bad shape, but once cleaned up, it turned out to be pretty darn nice. The 48 Surpass looked just like the picture, but still needed some internal cleaning.

Both engines were completely disassembled and parts cleaned in my Harbor Freight ultrasonic cleaner with 1 part LA's Totally Awesome cleaner and 2 parts hot water. The Enya needed some parts but fortunately I had them on hand. The Surpass really didn't need anything but a screw that I had stripped the head on trying to loosen it. The bearings in the OS could have been replaced but after cleaning and oiling I thought they would last a bit longer. besides I did not have the right bearings on hand.

The Enya has been run, the OS has not yet. Both have very good compression and should provide many more years of service. below is a video of the Enya as I disassembled it. I do glow engine repair, cleaning, rebuild. So if you have an old tired engine and just don't feel like messing with it, send it to me and I can refurbish it for you. I have a playlist on my YouTube channel showing customer engine repairs.

This is the second video using the RunCam II mounted to my Decathlon. The first was poor because I did not turn the image flip setting off. It is off this time and I have a much better video to show for it.

I was contacted by a fellow modeler a few weeks ago. He had a nice 170R3 that needed some bearings and check out. He thought maybe a valve was stuck or one cylinder was light on compression. He asked if I would be interested in fixing it up for him. My response was HELL YES! NOw when this engine arrived it looked pretty well cared for as you can see in the pictures.

Once I began the disassembly I quickly discovered the issue with the engine. It had stuck cam followers on two of the 3 cylinders. I am documenting this rebuild on my YouTube channel. I think the videos tell a bit better story than I do. Check them out.

Well just over 1 year after purchase this airplane makes its maiden flight. I have powered it with an Enya 80-4C engine. The same version engine I used way back in 1989 when I was flying the Great Planes Super Decathlon. What a great combination this is. The airplane required only a couple of clicks of down trim. Fairly strong winds right down the runway made the first flight a bit anxious, but that feeling was soon gone. Just a great flying airplane.

I have a complete set of awesome 1980's vintage 120 size 4 stroke engines now. All but one of these came from this forum. Some were solicited and some were not. All I can say is that RCG has some of the most awesome members, hobbyists, and friends around. A huge thank you to Jim, Chris, Jeremy, Michael, and Scott for either selling, assisting, or providing these engines to me! This is a set I am very proud to own and do not plan on parting with. Thank you guys!

A very good friend has sent me one of his FOUR Saito FA-120 engines to evaluate, run, and possibly purchase. Now this was the first 120 Saito mass produced and sold. It was released around the 1981-1982 time frame. I have found very little information on this engine aside from a review by Clarence Lee, , and the notes from departed Bill Robison,

I have been unable to find out much more about this engine. I started a thread about them on the Engine forum and few people have commented. It would seem that this is a rather rare engine. I do see one from time to time on eBay but not very often. I want to own one just for the sake of it being so rare. Here are a few videos I have made on this engine. It runs quite well.

For those BLOG readers that do not necessarily read the glow engine thread forums, here is a synopsis and videos of this engine. A short time ago I posted about 120 size 4 stroke engines from the early 80's. Those being from Saito, Enya, and OS. Well I received a couple of comments to that regarding the fact that I was missing a key player from that group, the YS F-120.

Quite honestly I did miss that. In fact I never even considered the YS F-120. I had never owned a YS engine before and honestly I was not sure when the F-120 was released. As it turns out an incredible fellow, Jim, has three of the these vintage engines that he acquired from another source. These engines had been stored in a hot humid Houston shed for many years untouched. Jim, being the awesome man he is, sent me one of these engines to clean up and get in running order. I gladly accepted and began the task.

Now YS engines are a different breed of glow engine. More complex than any other 4 stroke engine of the group I mentioned. I had some research and homework to do. Now I quickly found that documentation of these engines is somewhat difficult to find and limited to a few documents. Why this is in unknown since these engines are still in production. Well not the F-120, but the brand. I could not even find the proper instruction manual for this engine.

Since receiving this engine I have done and initial inspection, complete disassembly, clean up, reassembly, and now the first run. I...Continue Reading

Are you looking to get into the rapidly declining glow engine market? What the heck sort of question is that? Why would I want to get into a dying aspect of the hobby? Well the last two are valid questions. I am a glow engine fanatic and always will be. Yes I have tried to electric stuff but it really just didn't do anything for me. The gas/glow engine sector of this hobby is the foundation of RC powered flight. Unfortunately most new entrants to the hobby are quickly sucked up into the electric scene and seldom get the appreciation for the glow powered arena, and this is truly sad. Fortunately I have seen that change at the flying field I fly at. It was a 85% electric site several years ago and now they have an entire pit section for glow power only! That is really huge in my eyes.

Believe it or not glow engines maybe on the decline but there are millions of glow engines NIB, lightly used, and heavily used available on the market. These are also available for a fraction of the cost of buying them retail. Now do not get me wrong I am NOT bashing buying retail at all. Without retail sales the market would be doomed much faster. On the other hand if you are curious about a glow engine, very high quality and inexpensive engines are available for you to 'stick your toes in the water' with. Nearly 99% of the engines I buy are from RCGroups, eBay, or the 'other' big US RC forum. I have bought my share of retail NIB(New In Box) engines from 1988 - 2001 so don't...Continue Reading
