Formerly titled The Glow Engine Enthusiast. I have changed the name to better reflect the content I choose to post here. Yes this is still and will always be THE largest RC airplane glow engine video database in the world. However I have stopped the hobby of RC airplanes and owning and operating glow engines, hence the channel name change.
Webra T4-40 Friend Run
At the suggestion of a good friend I run with two props and two different plugs.

Webra Speed 61 Run After Ring Replacement
Awesome
That's quite a coincidence; my Enya 80 was also my first rc engine as an adult. I still have it. Runs beautifully. Had it in SIG Citabria years ago.
Excuse me, I'm relatively new to the hobby and I'd like to know how to get started? For example all the equipment I'll need and how to set everything up pre and post run? Thanks!
First off, welcome to the hobby. There are forums such as RCUniverse and RCGroups with threads and sections to assist you. That is not the function of this channel nor something I have the time to engage in.
@@dmrcflyr2 oh ok, I'll check them out
Brilliant demonstration video. That has really helped me understand how to carry out this procedure. Many thanks.
Very clearing story SIR,i'm 2 stroke mechanic,your hands show your experince, i never trust internet story's from People with clean hands or smooth you tube BABY face, Internet geeks ruïn the hobby,thanks you for your video ,totally correct, wd 40 for cleaning ,perfect,moist removal,perfect,love your treu facts,total correct!
ОГРОМНОЕ ВАМ ЧЕЛОВЕЧЕСКОЕ СПАСИБО, УВАЖАЕМЫЙ ДЭВИД !
Dave, I must say, I'm quite impressed with how the TT FS91 seem to perform in this video. I just picked one up, NIB off of eBay. $169- and these days (2024) that's a pretty good price. I want to put it in my brand new Great Planes Revolver. After reading the comments here, I think it wise to replace the original plug with the OS type F- the one you mention in this video- to ensure I get the RPMs, both high speed and idle, that you achieve in this video. I'm just wondering how long of a break-in will I need to be able to trust it, sideways mounted, in the Revolver. Also, I was wondering your thoughts on mounting it inverted. I do have a FS90 Enya mounted upside down in a Goldberg Chipmunk and it runs quite dependably. The Revolver seems to have adequate ventilation in the lower portion of the cowl, eliminating the need to cut a hole in the side, making it more aerodynamic and aesthetically pleasing. Thank you for all your efforts in providing us with these fascinating engine reviews. This one was quite useful to me.
I cannot say how long it will take you to ‘trust’ this engine mounted sideways. Personally I never liked an inverted engine. I had several and only so-so results. I do not recall ever having many issues side mounted and never any issue upright. For me it all boiled down to how much time was spent flying as opposed to dicking around with an engine at the flying field. I chose to say the hell with how it looks I would prefer to fly reliably and enjoy instead of toiling over fuel draw issues or whatever. So my opinion doesn’t mean dick. You choose to fly and mount the engine as you desire. If your experience with inverted engines has been good then why question it? I do not have enough experience with that particular to say one way or the other. All my videos show is the truth and facts for a particular engine at that moment in time. There are far too many variables to to give you concrete answers. There are some things you simply must choose and experience for yourself.
@@dmrcflyr2 Thank you so much for your thoughts, Dave; I will do as you suggest and work toward experiencing it myself. Before installing this engine in my new ARF kit, I will of course run it on the test stand for run-in. I will mount it in the different configurations and carefully tune and test for static performance in the different positions. I'm also thinking this might be a new angle for you to tackle in your excellent videos (no pun intended) since so many of us are installing engines sideways or inverted. Thank you again for your prompt and professional opinion. Respectfully, Floyd-
I was kinda worried that without the cover the belt would slip off the cam pulley. Or is it valve pulley for this engine? :D
There is no force in a direction to make the belt come off the gear. The cover is simply to prevent debris from fouling the belt and gear. There are no valves or cams in this engine. Read the linked review article for a full description of this design.
Great video! Congratulations
Très beau moteur et un beau bruit
Continue les vidéo très intéressant et félicitations bonne journée à vous
Thank you very much for recording the video.
Is denatured alcohol as hydrophyllic as methanol?
What is the measure of how hydrophilic methanol is? Where did you find that number? Can’t you use the same process for getting your answer here? All alcohols are hydrophyllic to some degree.
@@dmrcflyr2 Wow David! Quick response or what? Good to see you back on the Tube....really missed your expertise and knowledge. I was hoping that using denatured alcohol would pose less of a risk re: corrosion vs methanol.
Well the intent of this video was to simply show a POSSIBLE alternative to making a fuel; basically an excuse to make a video. These engines still require a form of alcohol to operate and with that they will still require the proper maintenance. That includes completely clearing the engine of fuel residue and using a good after run oil to keep internals lubricated. As I asked above, what is your measure or numbers for the hydrophilic capacity of methanol? If you do not know then how can you possibly compare it to denatured alcohol? Thus, what difference does it make? Proper maintenance of your engines still applies so I do not see the relevance of the question. As long as glow fuel is available, using denatured alcohol is not required. Don’t you think if denatured alcohol was less hydrophilic or ‘better’ than methanol, that glow engine manufacturers would recommend its use instead of methanol?
@@dmrcflyr2 Point taken, thanks
Howdy David, I always enjoy seeing different and unique engines. Thanks
Try nos fox miracle 4 stroke plug. I bought a bunch years ago. Nothing today seems to work as good although the O.S. F plug seems to work well for me.
Runs really good on #8 plug to be a 4 stroke, the best performance in a 4 stroke with a #8 plug i ever seen!
Honestly this engine isn’t like a four stroke though. I thought it ran best with the F plug
Are there any NOS timing belts around for these engines?
Would NOS be fine to run? Or would they be hard? Are new belts available?
Very doubtful you will find replacement belts for these engines
Hi David. Glad to see, you didn’t give up. And congrats for this cool run.👏 Also thanks for the image of the valve timing. I’m absolutely with you. It looks pretty perfect. And as I also mentioned about the OS F plug, I was happy to see this engine running so fine with it. That’s quite the same as I experienced with my Webra T4-40 engine in the past. 👍
It's just murphy's law! - as soon as you try and show something to someone...
Brilliant video and well explained.
My SF61 all of a sudden wouldn’t start. Usually it’s super easy to start and very stable. Found out that the plug screw was gone. Must have vibrated loose or something. It’s nr 8 on the explosion view. I don’t understand what it’s for. Anyone who knows?🤗
I cannot find a #8 listed in the exploded view I have of that engine. if it is the screw in the center of the rear cover, you are correct, the engine will never start or run with that missing. it does not allow a vacuum to be created in the crankcase if missing. It is there for when using a pump.
@@dmrcflyr2 It’s the short screw just beside the fuel intake nipple on the carb. There’s also a gasket on this screw. It will not suck fuel without it in place, so maybe just an extra place for a fuel nipple?
Obviously it will not suck fuel without it, it is creating an air leak. I don’t know why that screw is there I no longer have that carb. Burt suffice it to say it does not matter the purpose only that without it your carb is useless. Doing an internet search for OS 7L carb turns up lots of hits.
Hey David, apart from the fantastically running laser 80 in this vid and the equally lovely Noah cat, I've a question: for long-term storage, after ending a session, do I save the bearings inside an engine by "drowning" it in FAI fuel? I mean, will it protect against the effects of any tiny residue left from the 12% Nitro fuel I'm using (I always "dry out" my engines after each session)? Or am I just wasting my time, thank you in advance, Regards Harry
Long term storage should always be done with an oil of some sort and never fuel even if it is FAI. Methanol still attracts moisture, moisture equals rust.
@@dmrcflyr2 Thank you for the valuable feedback David, off to dry out the particular engine of mine drowned in FAI fuel and fill it up with ordinary 2-stroke oil (haven't got specific after run oil). Regards Harry
Hi David. I came across your channel quite by accident and wish i had found it years ago. Some of your engine videos take me back to the 50s 60s in England when i was a lad just getting into model making. my first model was a Cox plastic control line plane with a cox Pee Wee motor. then i graduated to making my own Balsa and tissue paper models powered by small diesel engines, we would make our own fuel ( castor oil, ether and paraffin <kerosene>) but i digress. I have been looking for about 5 years for a long ago discontinued OS four stroke engine which was for model cars. OS FS 40S-CX and after finding your channel i thought this guy may have one, know someone who has one or can point me in the right direction to find one. I would have liked to have emailed you direct but the 'About" section in your profile no longer exists so there was no way to find your email address. Accept my apologies if i have been waffling on but my hopes have been raised just by finding your channel.
Hi Andrew. UA-cam has simply changed how you access the information in the About screen. On the channel page instead of an About tab you go up to the description beneath the channel name and click on the arrow > pointing to the right to see that information. My email address is easily seen there. First let me say that many things have changed in my life since I started this channel. I am not an engine collector as I feel there is no point in that. Most all of the engines featured on this channel are LONG gone with maybe the exception of those made in the last year. I have never owned nor do I know where you can find the FS 40S-CX engine. I hope you enjoy watching my videos. Cheers.
No matter what oil is in the fuel, the OS engines with piston ring always run well.
Great video David. Good comparison of prop performance. I think the transition issue is the plug. It’s a two stroke plug and webra make hotter plugs than the 4. I’d run it with the IS F it’s way more suited especially with low nitro fuels. Other thing you could do is run high nitro fuel like 20% on this plug.
Well the funny thing is that the Webra #4 plug was what was recommended in the manual that came with the engine. That is why I bought them.
I enjoyed watching this engine run as well. I think I agree with you David, I need to look at previous videos but I remember the engine running a little bit smoother with the #F glow plug. Especially noticed the difference at low rpm.
Great videos###
Hey, Dave! Can you tell me in which order does the crankshaft spacer/washer go in the assembly? I was given one of these (R/C version) from another club member. However, it was in pieces and missing some pieces. One of the missing pieces crankshaft washer. Obviously, the crankshaft has quite of bit of end play with out this washer installed. I saw a cranshaft washer shown in one of the pictures on the Sceptre Flight review for this motor and I'm trying to make a substitution using a prop washer I had laying around. However, I can't seem to find an exploded view of this engine anywhere on the web to show where it should be installed. The tapered cone design and lack of bearings of this engine is also new to me. Most of my engines seem to use woodruff keys instead of the tapered cone design. Just can't seem to figure out how it goes together: hoping you might be able to shed some light on this for me. Thanks!
Honestly I cannot answer the question for that engine as I no longer have one. But there will be some end play in the crank if it is a bushed bearing engine. I also cannot advise where to get a suitable replacement spacer. These are some of the issues with obtaining older engines. It doesn’t help that yours was disassembled to begin with. Good luck.
Happy to see this beautiful engine back! Shes tricky! Sometimes, likes load, and not that much RPM, sometimes less load with more RPM. Anyways... a beautiful engine, that I ll be glad to have just to appreciate and of course run it. Thank you David
It's good to see this webra engine test with 4 different props, i think maybe the webra#4 is not performing as well as we saw on the other videos with the os f glow plug, at least at this stage in the break in process. As always your vids fulfill my need to hear glow engines running. Thank You!
I agree the Webra plug seems a bit weak.
Glad to see the Webra 40 back with a 4-prop test, as one guy below suggested I'd stick to what works best with regard to glow plugs, that being the OS F generally. I'm somehow convinced it should both idle and transition much better with that plug. Nice run though, thank you.
Hi David. I still think there is a little timing error in the valve timing. If you disassemble the belt cover try to find a little point on the upper belt gear. I thought seeing a little point slightly on the left side top (about 11 o’clock) directly under the teeth of the gear on your disassembly video. Can you confirm that? Because this point should be absolutely on top as I remember my engine I had. I always ran my engine on OS „f“ plug and it ran very fine. Much better than the original plugs of webra.
Perhaps you can watch this video. ua-cam.com/video/3jXzohmcvEs/v-deo.html I am not sure how much more I will be messing with this engine.
Hi David. Thanks for the reply. Well, these engines are often spicy with their timing. The smaller is even more a diva than the large one. In worst case the rotary valve doesn’t seal enough anymore and when exhaust timing is too late it blows back to the inlet. Otherwise with too early timing it may struggle very hard. All in all I wish you good luck and a lot of patience with this little beast 😉.
Hope to see it run again, maybe with an 11x6 and a few different glow plugs. I'm glad you are enjoying Wisconsin!
Hello David, big fan here, I recently bought a brand new bully 1.20 LS from an old timer, there are no videos on tuning the carb and internal pump and very few info in forums, is it possible to feature that engine on your channel somehow ?
Sure, send me yours.
Nice I picked one up about a month ago in a package deal 100 bucks for the engine and plane kit and all to complete it I've been running os in my planes for years and have always been pleased with them great to see that you're still enjoying running rc engines as a hobby keep the videos coming 👍
Another well manufactured engine. It should be another great acquisition of yours.
very good run. ,its an OS. i prefer the ring engines. i still have a new,61,fsr,ringed motor,never started. maybe, one of these days.
Got one myself, also new in box. Will keep that way for a while. Nice video as always, enjoy watching 🙂
Nice run. I suspect a single flip would get it started, but I know you have issues after so many years of hand starting. Great engine. I’m breaking in a K&B 65 Sportster. After around 30-40 minutes it is only getting close to your OS initial run. The SF are the the best series.
OS never dissapoint specially the SF series, in my opinion the golden era of 2 stroke OS engines.
Nice steady first run! funny I have just come in from running a OS 25 SF flick started and ran spot on! OS!! say no more, the SF range have always been top of my list, I have three 25s WHY? can't stop running the things from the age of 10 now 65!!!
Thanks David! Sounds really good.
In some engines plug so hard closed properly!
Ah, yessss...The moment of satisfaction when an old used or new-2-U glow engine fires up easy for the first time, or the cheap thrill when it breaks into full tenor and you feel the resonance through the needle valve. Its all still there every time I make a run like this. 'never thought I could love a Thunder Tigers or tune a Super Tigre, but thanks to your show, all are now tamed dragons and pet cats in my Ready Engine Cabinet. Castor oil is not as strong as rat poison, but it is still addictive. Thanks, for the videos.
Being that the carb and exhaust is opposite between these engines, I'm thinking that one runs clockwise and the other counterclockwise. Just my guess.
Yes that would seem to be a reasonable deduction. The only review articles I could find cover the 1044 version with the carb directly mounted to the left side of the head. No mention was made in that review about this operating in the opposite direction. Since this video I have run the 1043 version with the intake manifold and carb attached to the rear of the head. It too operates in the normal dirrection.
@@dmrcflyr2 I have a couple of Abitar 120 engines that can run in either direction just by switching the carb and muffler around. It's especially desirable if using two of these engines on a plane for better balancing and there's no cam timing adjustment needed. There is a timing option available for changing the power band I think because the cam pulleys have "A" and "B" stamped on them. That's why I thought your Webra engines rotated opposite of each other due to the location of the carb and muffler. I have a Webra T4-80 but because of the way the carb and muffler is mounted, I don't have a way to test that theory. As always, thanks for the great content you post.
With 25 nitro ONLY 7800! No powerhous engine
Ouch
That engine is quiet. Awesome sounding gem of an engine.
I have a Webra T4-80 that runs very well. I experimented with a spark ignition setup and it also runs very well on Trufuel for two stroke engines. I'm glad you solved the problem with your engine and got it to run great.✌
Much better engine ! Lol
I had one a very long time ago. When it ran, it didn’t run that good so it’s in a box with the other 400 engines I have. As a collector. Now
Interesting. What are those 400 engines going to do for you? Can you buy groceries with them? I can understand collecting precious metals, or jewels, but rc glow engines have no intrinsic value.
