All about NITRO engines 

Glad to see people still preaching the fun that is nitro. Nitro has always been the top dog in rc for me, the most fun. Great video!

Nothing can replace the thrill and adrenaline of nitro airplane it's an experience that you can feel only when you fly it. Sir your videos are as always phenomenal ☺️

Nothing like the smell of Glow Fuel in the morning!! Great throwback!

" I LOVE THE SMELL OF METHANOL IN THE MORNING."

I primarily fly glow and routinely rebuild both 2 and 4-stroke engines. I know these things very well and still learned a ton from this video- you’re an amazing teacher and a wealth of information. Thank you for sharing!

Electric RC guy here, I'd love to see how these get installed on a model. So yes, please make the build video.

blast from the past, I remember having to save up for my Saito, but the sound always made me smile. Still mounted on a walnut stand on my desk

I've always been intrigued by miniature engines, that was a very interesting & enlightening video, thankyou.

I try to learn something new everyday, and after more than 35 years of playing with every type of radio control vehicle you still helped me achieve that goal for today! I already knew most of the information that you spoke of in your video, but all of that knowledge that I have came from years of experience that were either frustrating, expensive, or both. I would have given anything to have this information available to me all those years ago. Keep up the good work.

Ahhh.... The smell and sound!!! Thanks for the video!!! U got me down memory lane.

When I first started flying in the 80's one off the more experienced guys turned up with a big pattern ship which had a pipe on it. I have to say that when he screwed the main in and it came on the pipe I legged it to a very safe distance. It was absolutely terrifying and exciting all in one go.

Awesome, I havnt flown glow motors for a long time now, and Im happy I also learned a thing or two as well. Yeah Im keen on seeing a build, and also while you are at it do a tuning vid, will help a few out I think. This is a great tangent to explore. Thanks Bruce.

Excellent Glow Engine info. Had many, many Glow engines before I went to Electric. A lot of Glow engine info I was not even aware of. Thanks for enlightening me... ;-)

Your personality and way of speaking made this video 2x more fun to watch

Thanks for the video! Very good timing as I just bought a Traxxas 4-tec as my first nitro anything.

Having grown up on nitro motors in the hobby, nice to see it addressed! Thanks. I'd like to see someone make a nitro quadcopter - that would be impressive.

Well, put Bruce, really good information as always... :)

I'd really like to.see you take on tuning a nitro motor maybe even do a blind tune or 2 so show us how to find that sweet spot from anywhere on the carb needles... 🍻cheers🥃

Most important maintenance of a nitro engine is the after run of a nitro engine. The methanol corrodes the alloy but the Nitro attacks the alloy, when this happens the nitro "Pitts" the alloy leaving tiny pin sharp shards. These shards break off under combustion and score the sleeve, and also, finds its way into the bearings or bushings whatever the case me be. After a days running I unplug the models fuel line from the carburetor. I have a seperate fuel tank with 100% methanol, and I run the 100% methanol for about a minute to burn out the nitro from the engine. One thing to know is when switching from nitro of any content to 100% methanol, the engine will run lean for a 20 to 30 seconds than fall off high idle when all the nitro is burned out of the engine and then run at a more respectable idle. I use my finger much like a throttle exhaust to limit the rpm by placing my finger over the tuned pipes stinger and blip the pipe to keep the rpm's down until the nitro is completely burnt out of the engine. After the nitro burn out I use Marvels Mystery Oil as a after run lube. Ten years on an engine and the internals are like brand new with no ugly darkening. It is what it is.

ahh, the joy of a simple sig 4 star 40 and a saito 50. gonna do it for the summer. the most perfect combination of airframe/motor and fun i have ever had

Excellent information, diversity of the conversation, enjoyable.

thanks for the info. I just bought a 2.43cc nitro engine for the time being.

Hi Bruce. Great video and review of nitro motors, I still have my nitro engines now I just need to find a balsa kit to build. Now everything is foam and RTF electric. I miss building a new plane in the winter months. Thanks for sharing your experience with nitro.

I've found so many cool things about nitro engines recently (and learnt a lot a bout combustion on the side) that It really makes me want to build an old-school trainer, use all the cool radios and servos we have now and fly high alpha like I used to do with my dad's planes. But now that you mention tuned pipes man that opens a whole new world of cool ideas I didn't know how much power they could add. Also there is quite a few smaller gas engines now, and I'm sure with some fuel additives they can get to close to the power to weight ratios of glow engines, without the mess.

Bruce - i really enjoyed your informative and enthusiastic perspective / description of 'Glows / Nitro's'. As you commented, I am really enjoying discovering the challenges and drama of flying a glow; relieving my youth with model boats!. PLEASE do a build with a glow. I would love to learn more - and as others have commented, would like to learn more on tuning. I am getting there - but it would be good to hear from a pro. Thanks. Keep up the great work!

Jeez after you mentioned tuned pipes, I started searching and I saw Dub Jett being mentioned in some forums, I had no idea they even existed never the less made very cool engines and still sell them! With less and less glow engine options in the market, this is amazing!

Excellent video Bruce, very informative. :)

Sounds like interesting fun will be looking out for the nitro build bruce👍👍

Excellent video!!! Thanks:)

Happened to stumble upon this video as i acquired some nitro/glow engines. Super informative ... Learned some new things. And I recognize the voice from your other channel Bruce. Didnt realize this was your channel too... How cool! Again, thanks for the education! Super helpful!

Thought for a moment I was on Joshua's channel ... because I learned something to day. Grew up with these motors, but never knew about the timing adjustment with the glow plug choice. But then not much choice in glow plug was available in those days in my neck of the world.

Thank you Bruce very good video and yes a build video would be great.

Fascinating! Thankyou

It will be awesome to see more about these engines and some gas or petrol too!

Thanks for making this video, I'd like to see a build video 👍💪

just watching the video makes me smell the old castor oil, I think I been around RC nitro motors a little too often lol

You know I still have my 4 stroke motors. This next summer going to have them flying again. Miss that kind of flying

Thanks for the great video!! I'm new to the hobby (and had only an electric trainer), and have just won an older, beautiful and well built, plane in a raffle. It has a Webra Blackhead 10 ccm engine. Being new to glow/nitro (and the hobby in general) I really appreciate all the info!! I'm excited to go though it, give it some love, and hopefully get the plane in the air very soon! Thanks again!! 👍

Old school or not. Over Half of my new builds either ARF or kit are built with Glow engines! Nothing beats the sound. Smell. And sight of a plane spewing smoke while taking off!

great video!

Lovely Bruce, fab video definitely do a IC build vid.

I have an old OS max 40sr that's missing the piston ring, any ideas where I could get one ?

Very informative film had one gifted to me when I was wee 40 years ago had no idea how it worked had a wing bolt thing in where you have the glow plug on yoursIt must have been a 2 stoke as you could see the cylinder my dad said it worked like a diesel. As a curious observer it would be As a curious observer it would be nice to see these running. :)

Great video Bruce! I took up the hobby around 5 years ago using electric planes, and decided to try nitro last year. I love it! I wish I had seen your video then, it would have answered a lot of my questions. This is the only explanation I have seen regarding glow plug ignition timing, which had me scratching my head until today. Please do the nitro plane build video!

'Definitely you were a school teacher. Wonderful teaching gift you posess.. I learned so much from this and just at the right time too! Just fascinated by these engines, and know I will retain it. Thanks 🇺🇸

Interesting, looks like you have been in my garage with the exception of the asp metal door stop,,,

Awesome video thanks

Brilliant video and well produced and everything explained in a simplified way. Im flying model aeroplanes since May 1986. My first plane was an MFA YAMAMOTO with an OS 40 two stroke. The vast majority of my planes are glow planes both two stroke and four stroke. I do have a few electric planes and I enjoy them too everybit as much. But I still love to hear my fourstrokes and I still love to see a smoke trail across the sky for realism. Enjoyed this video very much. Thanks for sharing.

I’ve flown glow for probably 25 years but I still enjoyed this video and I’d like to see more glow back in the hobby. Electric started out as a novelty and now is mainstream and glow is the novelty. But I believe it will come back as a more mainstream power source. Especially if the fuel cost would come back under $20 a gallon

Those were the good ole days! I'm still using them but mostly use electric conversions now for the simplicity of it!

Most the guys at Frogs Hollow fly nitro - nice to get some info so when they're talking I have a vague idea what they're saying! 😄👍😎🙃😃

A very exceptional job of catering to us Flyers who love model aircraft engines and the smell of the castor oil and methanol

Very informative.

Nostalgia, use to play with these all the time.

Yes, would very much love to see a nitro build. You probably forgotten more than many of us know about nitro. 😀 I have picked up a few old airframes that will not easily convert to electric so nitro is in my future.

Awsome video. Im jumping to nitro!!! How do I use tuned pipes?Could you plaese do a tutorial? Love your videos. I learned alot with you

The nitro engine won't need recharging the model receiver/servo controller will still need a charge as will the control transmitter. Fascinating info. Love the smell of Castor oil the same as Castrol M.

Very informative and helpful, great video.

Cool a build... can't wait....

Great stuff Bruce can you tell me what is the best way of cleaning a nitro engine that's been sitting for 4-5 year's with old fuel in it

I'd love to see the build video Bruce!!!

Hi Bruce, good to see the old glow engines out. I have some old engines that my father gave me. One has never been used and the others haven't been used for 25-30 years. As you would guess they no longer turn over. I would love to see you do a video on how to free up and clean one of these engines bringing to back to life. Cheers.

Great video Bruce! I just got back into nitro as I purchased a Toyan 4 stroke overhead cam engine and installed it into a RC car. I am having a blast getting back into Nitro. If you are interested I have done several videos about it.

Cool video. I have a question I have a os .52 surpass I want to put it in a rc nitro truck how should I gear it any thing helps thanks

Started with Nitro and i can't stand electrics, to easy. I love to tinker and tune. Only real downfall is fuel costs and noise complaints.

Awesome video and yes please to a nitro build video !

An interesting introduction of glow plug engines. A little test run to hear the difference between 2 and 4 stoke would be nice. AND perhaps a brief mention of Diesel engines too. When I was younger about 75% of us started the hobby with 2,5 ccm diesels.

Electric will never be the complete experience, ever. Nitro is the real deal in terms of experience in the RC hobby realm.

What is the best way to tune a nitro motor always having issues. Thanks great content

Excellent informative video

Still using castor in all my four strokes. Never had any bearing corrosion.

I have a Thunder Tiger 91 4 stroke (hardly used) it gave me 8 flights then now won't start. Not seized, turns over fine with glow plug out, but very hard to turn over when plug in (even with no fuel). The valve clearances were off, I adjusted them back to specs, still won't start. I noticed the pushrods for the valves appear bent at the top. are they supposed to be bent? Should I straighten them? Help!

Extremely informative intro to nitro! This old glider flyer learned stuff he never imagined ;-)

Counter rotating glow engines for twin engine planes? Anyone have tips on where I can get a pair?

what is the best fuel for a 4 stoke .. can i use 5% that i use with 2 stoke

Very very nice and informative presentation.

Yes please do a Nitro Build. _ Great Videos - thankyou

a quick question what about the electric side as what do you need to run a gas motors battery etc

Concerning glow plugs, my experience tells me to use a hot plug at elevations like Bogotá, 2650 meters above sea level. Normal or cold plugs at sea level. It also depends on the amount of Nitro Methane in the fuel.

Hi I have a important question….. I have a .46 magnum xl 2 stroke engine that for some odd reason keeps rotating backwards. It has never done that before and the prop gave me a painful cut because of it. It also has trouble staying alive and I just don’t know what to do. Do you know or have any clues on how to fix this problem?

I have an old fox 40 engine but now the carb is frozen stiff. Where can I order another?

What electric motor is equivalent to a 60 size 2 stroke nitro engine?

Great video my friend. I do a loooooot of nitro. And your right , it’s a hobby in itself. Great topic. Value your thoughts on the topic

Do a build video. Also a tuning guide for glow would be great

I have a question regarding oiling of the rotating parts in a 4stroke....wouldn’t it be better to have a nipple running off a muffler a tubing to the lower crankcase with some of the oil being not burnt for lubrication and having the compression ring fully seal for more power?!

Very informative! Bruce,You do such of a great instructional video! thanks for all your hard work! thank you from Flyboy-NXS.. USA have you done a four stroke in-depth tuning, trouble shooting, maintenance, and most importantly!.....any preventive checks, to reduce in flight Engine stall? You know!..The dreaded "Dead stick". :/ Cheers To ya Bruce

A great walk down memory lane Bruce. I still have some of these motors but haven't used them for years :) Regards, Pete

what brand and model of the two stroke 22000 rpm ?

I've been given a couple of these. Time to have a go. Yeah. (I suspect it might pay to start it outside though !).

I was hoping you would show how to tune a 2-stroke

Great vid pops!....I love nitro...so tired of fpv and quads.

would luv to see a Nitro build please :-)

Oh Dear, nostalgia! Well, you forgot to mention that those engines were very expensive at the time. I just read the magazines over and over, but never was able to purchase one... The really hard core engines, were the star configurations you would find in some WWI type aircraft models.

yes please on build video. If you could, a setup or tuning primer would be more than useful as well!

I've got 2 Saito's, a 90 and 120, they both don't rotate, I need to pull them apart and see if salvageable(I did put ATF in there 20 years ago).

I like these

with more gas engines replacing nitro can you show how to measure the RFI coming from the CDI ignition, as i have one engine that is completely swamping my frsky tx

Been meaning to get my old os max going 👍

Rotation can a two stroke run In either direction,that is clockwise counter clockwise with tha same power? I have a OS 91 SUPWR MAX IN MY 700MM HELI DONT KNOW WISH WAY TO SPIN IT TO START IT. ITS COMPRESSION IS VERY HIGH AND IN NOT TIME RIP UP THE STARTER SHAFT. ITS TO A POINT WHERE I JUST GAVE UP. SAD CAUSE ITS A NICE HELI,BELL RANGER FULL BODY there two flats on the starter shaft And two set screws set as tight as they can go with lock tight does not hold any advise?

Hey bud, I'm Glenn from upstate NY. USA, I'm just getting into the Nitro hobby but do you have any how to videos on startup and tuning the carberator? All the videos I've watched so far, they just reach down and adjust without telling what their doing and why they're doing it???
