Overview: Nitro engines (the OS55AX)

[@jdnpe]

Yes Bruce, please show us how to build and setup a glow model.

[@luisfilipemachado17]

Yes, PLEASE!!!! I have a nitro plain to build for 2 years, and as my 1st nitro plain, Im a BIT scared. Thank you again for all your help. Cheers

[@sparrow082]

I'm in an RC airplane club and I usually don't fly my own planes, i make one of the other guys in my club do it so they come back in one piece. Lol

[@hippychip1159]

Definitely, used to fly them with my Dad, before he passed away, I have fond memories that come flooding back when ever I smell model fuel. I have a model part built which he was working on when he die and would love to finish it in his memory, so watching you build would get wonderful. Cheers Bruce.

[@timwsac]

I would be very happy to watch a nitro build series Bruce

[@iitra]

Aaaaaahhhhhhhhhh when you spent 3 years pocket money on all your parts another 6-12 months putting it together for 10-15 seconds of flying those where the day 🤤👍🏻👍🏻

[@izwanmohd]

people still doing that 😜

[@sparrow082]

That's why I like flitetest foam board planes, all of that is true but you can change the build time to 1 to 7 days which leaves a lot more time to practice crashing. LOL

[@MrJackj30]

I was the best crasher at our club 😂😂😭

[@dcdurbin1]

Yes please! I love all these little guys, especially the 4-strokes!

[@mtyler2469]

Yes please I'd love to learn more about nitro in detail.

[@chrsfincher]

I loved this engine in every plane i ever had it in

[@bootsinshoes3198]

You already know everyone wants another whiteboard video. They're my favorite for sure.

[@chinookmech]

Going from electric to nitro. I personally love the sound.

[@jamesberna6099]

Thanks Bruce! You are the professor. Long live nitro!!

[@88Simen]

Sorry for the late feedback. I'm also interested in learning more about combustion engines for RC planes. Learning from you would be awesome. I'm sure a lot of us would be real happy to learn about this topic from someone as thorough as you.

[@john_h9281]

Great to see IC motors being talked about again ! I spent many years building and flying IC models then got the electric bug and all the IC stuff got sold on! Over the last few weeks I have decided to put a IC model together again with a 4 Stroke motor as the power plant! So your Video has rekindled the interest even more ! So yes please give us more vids on IC How about a vid on the differences between 4 and 2 stroke motors , their set up and installation How the fuel tank should be installed in the fuselage with respect to the carb spray bar (same height as the spray bar or higher than the spray) Fuel proofing tips Low RPM jet setup and top end jet tune !! How to decide which motor size to use for different size and weight models Looks like that could be quite a few vids !!!!!

[@nmsidewinder]

This video brings back a lot of memories. I didn't use this particular engine but I used a " Black Widow " engine on a model airplane I made. It was one of those airplanes that you flew in circles. It had control strings to it and all you could do is fly in circles going up and down ( and getting dizzy ). lol I never got into RC flying because it was to expensive and I had seen too many of them just fly off and the pilot going nuts because he'd just lost his expensive RC plane. It was always fun to watch them fly when two pilots accidentally were flying on the same frequency. That was a hoot. Once again you made a great video, thanks.

[@skyvidznz3544]

Well well i never thought i would see one of these on your channel Bruce , Incidentally i also have an OS Pet 0.9cc glo plug 17000rpm engine here at my home Its still in great condition too ... As a kid i flew control line planes . .Your video brought back many fond memories from the past . .

[@christopherbrowder4746]

Yes please Mr. Bruce, id watch a build series. Thank you sir.

[@hohtz]

Nice to see you again Bruce.

[@ruftime]

Yes, please! A trip down memory lane!

[@joacimwennerberg8310]

Yes Bruce! A nitro build, awesome. :-)

[@RobWhittlestone]

As a very poor schoolboy I avoided flying my builds because the risk and cost of crashing was so high. Nearing retirement and no longer so poor, I'm very tempted to get back into flying. So please show us a build Bruce! All the best, Rob in Switzerland.

[@FlyDreamEcuador]

Mr. Simpson's first unboxing video... Fine stuff!

[@VicknairDoesThings]

Please do a full nitro build!! I would love to see this side of the hobby in more detail.

[@peterihoy4908]

+1 for a Nitro build series :-) .

[@easystar123]

Brilliant video and very informative. So well presented also. Thanks for sharing.

[@bentackett6299]

I've been using glow engines for a long time but learned a lot in this video!

[@moodberry]

I have this exact motor. Its been sitting on a shelf for years. But I learned a lot from your excellent technical explanation of how they work. Personally, I like electric more, especially the safety factor, since you have to turn the prop over by hand to start them, and, if you have multiple nitro motors, that takes more time to get off the ground since you have to start them one by one, then do last minute tunings to get them in sync and get the roughness out of them possibly. But I do like the sound. It has the sound of power - more like a real plane. Thanks.

[@zolatanaffa87]

speaking of the sound of power, a few years ago before the birth of jet turbines for modeling, there was a Supertigre engine (a factory now disappeared, Italian) that was born for intubated fans, which had a specific power of 3300 HP / liter! !! it had a rotation speed of around 30,000 rpm and maybe more! imagine how much fuel he drank and the noise he could make!

[@maxd8720]

Can't believe I've never found your channel till now. Your content is absolutely amazing. Subbed for life. Nitro is all I fly, and is still much more popular than many people realize. I'm in Southern Ontario at some clubs or fields it can be 50/50 with glow vs. electric. I'll never give up the sound of raw power. I might do electric someday, but only if I HAVE to. Lol.

[@ericnrb]

what club?.got tips?.. i just bought a nexstar today and found this video trying to learn a thing or two possibly ..before the snow melts and i attempt flight. im also in s/o.

[@jawjohn101]

Very Nice and well done. You have convinced me to pull my new OS 55AX out of the box and get it going. A glow/nitro setup video would be nice as well..

[@sysmith9910]

Hi Bruce. I love flying my glow engine planes. I only got back into aero modelling a few years ago and was taught electric; which I like too, but glow engines give me a real buzz! I love the sound of an engine, the speed of my plane, and knowing a I can go flat out for 10 minutes without having to worrying about flattening a flight battery. Electric is convenient, but there will always be room in my shed for a glow powered model. Cheers.

[@chrispearson7303]

Would love to see a build,should bring back old memories.

[@hellspark]

Yes Bruce, I'd love to see all about how you do nitro! I actually just flew my first non-electric yesterday, so I've learned a lot about it on my own, but it was fun and I'd like to learn more. I actually watched your old video on changing bearings as I was rebuilding an old Thunder Tiger Pro 40 as my first.

[@remkojerphanion4686]

This is so good to see!

[@micky5150]

I would love to see you do a nitro build! Thanks Bruce!

[@joetaylor486]

Yeah let's go old skool 2-stroke! I find these wee engines fascinating

[@dram6262]

Yes a nitro plane build would be interesting.

[@FarmerFpv]

I remember porting them, cutting the connection rod for windage that way it will produce more of a mist of the fuel and oil when cycling through the combustion chamber. Putting tuned pipes on them. I do miss it a little but my workshop is a lot cleaner now lol Awesome Blast from the Past Bruce 🤘

[@greg0063]

I would love to see how you put one together there is always something to learn. I just started recently with Glow. Set up 4 planes, test flew, and happily flying. Its really cool not having to baby the throttle and worrying about the battery being over stressed. I still fly electrics a lot but it's really nice to be able to fly glow.

[@zimmy1958]

Ahhh the smell of nitro in the morning.... loved it

[@fgroen1225]

Great idea Bruce!

[@75ajw]

Learnt to fly in the 90s with an O.S. 40FP, and the whole lore and technique that went with glow engines was part of it. Better resourced guys had O.S., Saito and Enya 4-strokes. Great sound, those 4-strokes!

[@martinschyns1458]

Great Bruce. Yes please on a nitro / glow build.

[@tassierovers1200]

Hi Bruce. A video on the full package from build to flying a nitro model would be fantastic.

[@simonhall886]

I'm interested. Thanks Bruce. Reminds my of the Tiapan diesel my brother gave me as a kid. And my Dad explaining the dangers of using ether in your fuel :)

[@rotorismo]

Whoohoo! Finally an unboxing! I like video's about nitro engines. I eventually want to build and fly a model with combustion engine.

[@Helterskelter4]

Definitely keen on seeing a build with the Glow engine Bruce

[@DonDegidio]

Hi Bruce, Yes, please do a nitro build. Been a very long time since I flew a nitro powered plane. I liked the Top-Flite Headmaster best, getting about 20+ minute flights out of it with an OS 30. Afterwards, was into helis before my auto accidents caused problems with my back. I'm into electrics now to keep planes clean and much less noise, but do miss that smell of nitro engines.

[@leeberry6194]

Yes I would love to see a nitro build with a 4 Stoke engine and look at the differences

[@katherineburton1945]

Hi Bruce, my club fly almost exclusively 46 size glow models due to noise restrictions and it makes the hobby even more gratifying. It would be great to see some build/assembly/setup and proper running in videos to show everyone how to set everything up properly in comparison to electric. A short whiteboard video about deadstick landings wouldn't go amiss either, as many of the newcomers with electric just fly to their timer. Thanks and keep up the good work.

[@julesham5406]

Could you show us the difference between the cox .010 size engines all the way up to 4 stroke 50cc gas engines please?

[@phoenixrising4573]

Would be happy to watch:-). My first plane was an old nitro trainer I rebuilt, then built a low wing variant of a significant senorita with a .20 on it. Last I saw it's still flying but now electric

[@organgrind]

I love glow engines and their duration, so YES PLEASE.

[@AussieVeteran71]

That would be great to see .

[@andyschiffer6682]

I enjoy flying electric and nitro. Each has it's advantages. For me, the main advantage of a nitro is the longer flight time. I would enjoy a followup video on nitro motor maintenance.

[@ParaxSystemz]

I would love to see that.

[@juliansjames]

Ah, the nostalgia... Must get my JR Ergo 46 (OS 46) and Wot4 (Thunder Tiger 60) airworthy again. :)

[@amateurtech736]

I’d love that build series, I might even follow along. I’ve been thinking of making a nitro aircraft for a while but have no idea how

[@Peter195267]

Yes that would be great Bruce.

[@professionalidiots101]

Show is PLEASE!! love the comment about neighbors complaining.. I remember tuning a nitro car in my parents garage, the noise was horrendous.... Damn the neighbors complained 😂

[@shoominati23]

Windex and chux supa wipes are the best thing to get glow fuel detritus off of a model

[@agentbertram4769]

Bruce, my Beloved is furious with you matey. You have just opened up a whole new area of expenditure. :O) I'm definitely interested in watching a build. Especially as you already have the engine...

[@TheRumbles13]

I am very interested! Thanks for all your hard work. I am an experienced electric flyer, just bought a t6 harvard with an os 55ax In particular I would love a video on setting idle properly and tuning. As well as fuel mix and seasonal maintenance. Thanks so much and cheers from Canada

[@giorgiontanas8618]

Bruce thank you so much for an insight and explanation of these engines, it reminded me of my childhood, dreaming about owning an rc plane once when I grow older! I am 31 (born in 1987) and used to see these at my local hobby shop when I was an early teen and kept bugging my dad about buying an rc nitro plane... Ofcourse the answer was no, every single time! lol little did he know I actually really loved anything rc that flies and it wasn't just a juvenile phase I was going through, and what do you know? A few years later, I am building and flying my own (electric ofcourse) airplanes and drones with info and tutorials I found online, thanks to you and other youtube instructors like painless360 and the flitetest team! Cheers!

[@WillThat]

Funny you mention the .46fx. I have one my dad bought for me years ago to put on my trainer. Was only flown once.

[@barrycole8378]

Vince Sygall 3 hours ago I have converted all my glow engines to spark ignition. Much cheaper to run and a lot more reliable. Oh and a lot cleaner too 😊 Now THAT would make a good video Bruce. Go for it...

[@twitchfpv6797]

let's see the series! I would love to check it out.

[@jeffie8696]

Good stuff Bruce

[@13ahab]

Yes, I would love to build and fly one, I have one nearly built never finished it.

[@visioneerone]

EVERYONE POST YOUR FAVORITE GLOW MOTOR / PLANE COMBO My favorite motor was a YS 1.10FZ. Had it on a a.60 size U-Can-Do 3D, swinging an APC 16x4W prop on 30% nitro. Hit full throttle for more than 2 seconds in any attitude and it would rip the prop. Glorious :)

[@mbmrc5241]

Four Star 40 with a thunder tiger pro 46, or my Sig Kougar with my Irvine 53

[@termitehards]

masha Allah thank you brother, that was a flashback in time, i remember the time taken in tuning one, especially the rc car engines :-)

[@power-max]

Would it be possible to get a small glow engine for an endurance quadcopter? I'm thinking either 4 tiny ones or 1 small one driving an alternator and then powering motors

[@RCModelReviews]

Shhh... I'm quietly working on a three-engined nitro tricopter for the summer. That'll be a hoot!

[@paulinfrance5]

Pages or re marques but what sort of power does it deliver, on 12 x 6 ect props ?.

[@phantm24]

Great idea Bruce, I have flown nitro but am always up for a build video

[@oscarzt1652]

9:05 i am not an expert but oil goes through the crankcase first before the combustion chamber so should still do a bit of lubeing

[@JimN5QL]

Are you going to build a Balsa model? And are you going to cover the wings with silk and dope or are you going to use plastic film?

[@charlesphillips1642]

Off subject but what if frsky put a inductor on the signal pad on the rf modual for the antenna mod and would it have continuity on ground and signal pads

[@jjrotogeek]

Hey brotherrrr. I would loveeeeee to see a nitro series. I used to run a lot of nitro back when I was a kid and recently got back into it. Would really appreciate your knowledge on it

[@J_Renwick]

Nice review. I recently received some older RC parts. Included was a new OS Max 46 with what appears to be all the parts. I’ve never set up a nitro and wasn’t even sure I would try until I saw your video. Now I’m excited to get it running. Please do show us how. Thanks!

[@keithcarter9396]

A great review, plenty of good information on oils also. Can you list some high quality synthetic oil available in Aus/NZ.

[@paulhenderson9585]

what has happend to the glowplug when it becomes a cold plug ?when you remove the glow starter and the engine stops

[@bennietipton2820]

I’m definitely interested in seeing you build a nitro

[@tonybeverley5406]

Hey there Bruce I love nitro and gas engines aswell but recently I had a brain fart on starting my gasser edge 540 20cc ,thought it was coming through my saftey stand and tried to stop it with my left hand and lost my middle fingers.iam a bit nerves now with it and I am thinking of going to electric,what set up would I need for a calmato 40 sport low wing plane,motor speedy battery ect thanks bruce

[@pokiou]

YES... do a build. also do a video on the difference between two stroke and four stroke fuels... i'm switching from electric to Nitro. Also home made mixtures of fuel for these.

[@NormanLedoyen]

This was great! Do more on glow engines and the types that are out there. Also do the 4 stroke and more insight from you would be great. Also do the build and show us all the method you use to throw one together.

[@SteevyTable]

My wife bought me a crashed nitro plane a couple years ago. Seeing how to build one would be very nice.

[@olliea6052]

Awesome bruce! I just maidened a 20 year old seagull p51 today. A neighbour gave it to me after he saw me flying out the back. It had never been flown and i was scared of running the engine. I put a brushless setup in it and got it going that way. But if you did a tutorial......

[@LunaRendezvous]

You never to old to learn... I always thought the glow plug kept glowing when you removed the battery because of the residual heat from combustion, compression ignition never crossed my mind with glow engines.

[@hrholden227]

G'day Bruce! I've been a lurker for a few years and like your stuff. Yes, I'd be interested in seeing your glow build. I have a couple of engines sitting on a shelf, but I've never put one in an aircraft. My confidence in my ability to do so may well be misplaced :^D, so an instructional video by an an old hand would be grouse. Oh and I remember your little corflute biplane you once built! That went well.

[@krazed0451]

Can you not soft mount the motor?

[@pascallandry2853]

Yes. I vote do a nitro build video!

[@shiretook]

Would these engines run using what we call 2-cycle fuel, similar to a chain saw or weed whacker? Are there small engines available that use this kind of fuel?

[@RCModelReviews]

Yes, you can get gas engines as small as 10cc (0.61 cubic inch) these days and they run on a gas/oil premix just like a chainsaw. The glowplug (nitro) engines however, require methanol in the fuel and have a higher compression ratio than gas engines.

[@shiretook]

RCModelReviews Do you have any or could you recommend/review any 2 cycle engines?

[@miguelh.m.m.6911]

Nitro 101 please! Building of the model, installation of fuel tank, which battery can it use, everything you may need to fly it and maintenance, tools, etc.

[@demonprince9713]

I have a Dynamite .21 Mach 2 nitro engine that is pretty much new. Pre break in... When I start the engine it idles fine and revs fine but as soon as it warms up it runs full throttle even with the needle fully closed. Anyone have any ideas what causes this?

[@RCModelReviews]

Sounds like there's something wrong with the carburetor. There must be fuel and air getting in when it shouldn't. If the carb has an idle-speed adjustment, make sure it's not wound in too far.

[@philogre5771]

[@chrisshepherd8082]

Hi Bruce I know this video is a year old but did you do a build video ? I would love to see that as I am an electric flyer who is going to get myself a glow engine model maybe this Christmas so I have a lot to learn about it. Love both your channels.

[@dizzydrc]

yes!! This brings back memories. Nostalgia 😅. Would have loved to see and hear one run once more !?!?!?!? (hint hint)😉

[@axiomNES]

How about the difference between 2 and 4 stroke glow engines?

[@jsvno]

Your proposed project would be nice!

[@nickolayjelev6077]

Yes please!

[@timwingnut]

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

[@wyrefpv9553]

Awesome vid Bruce! New in the hobby so I've never flown a nitro so I would love to see a build of one. So please do a series of vids! 🤘😁

[@charlesphillips1642]

Bruce I bought a new back board for my taranis cause the pads got lifted on the mod and on the new board from horus rc there is a inductor on the signal trace and when I check for continuity it beeps on all 3 pads which tells me there is a short is that rite cause on the x4r sb with the inductor on the signal wire it also has continuity PLZ HELP I WANT TO FLYYYYYYY.
