Would be cool to see you make a split-pin crankshaft and accompanying camshafts to turn it into a proper boxer engine, so it won't shake itself to death from the crazy rocking couple caused by the shared crankpins

[@gundamned4879]

Flat engines are designed like that tho, thats what makes it a flat engine and not a boxer

[@allenl9031]

@@gundamned4879 Flat plane crank, like the Corvette Z06, which sounds awesome.

[@elden4267]

nop not the same thing@@allenl9031

[@SoylentGamer]

Well, the engine is tiny it could be a 1 can thumper and still rev to 30,000

[@ethancoy9237]

@@allenl9031 Yeah not quite the same there, 'flat' is referring to crankshaft setup for horizontally opposed engines, flat engines use shared crank pins for opposed pairs like a V engine, Boxer refers to those being 180 degrees apart so the pistons move opposite to each other and cancel out more of the vibrations making it smoother, both setups are still flat plane.

[@rileyneewton3806]

love the load testing as well demonstrates its really weight carrying capacity

[@halfnelson6115]

That cooling fan looks so cool. Reminds me of an air cooled 911 engine.

[@NonEuclideanTacoCannon]

9:58 I think it's because that belt is stretching out and the slack is getting pulled into the fan. You can see it stretching the first time it runs during revs.

[@MadEvo606]

but you don't really see it getting pulled into the fan, I suppose its just because of the high rpm. the pulley ratio is rather big so that fan is spinning like twice the speed of the engine

[@boyorougesauvage8584]

Can we expect a set of UEL headers to get that signature rumble sound ?

[@callumkingunderwood]

Still wouldn't sound quite right unfortunately, Subaru and VW are specifically boxer 4's. Boxers are flat, but not all flat are boxers. Boxers have the opposing pistons synchronised to reach TDC/BDC at same time as each other whereas you can see on this crankshaft the piston on the left reaches TDC at the same time as the piston on the right reaching BDC

[@BIGSMOKE-bl2lq]

You mean that vomit inducing sound that makes me that accepts that people have different tastes in car culture than me and respects that fucking hates with a passion

[@Phrew]

It won‘t rumble, it‘s a flat 4, not a boxer. Flat 4 is basically a 180 degree V, two pistons share a crankshaft pin. Boxers have a pin for each piston, which means the movement is different.

[@boyorougesauvage8584]

@@Phrew It will. even an inline 4 will rumble with UEL headers.

[@Jaime7188]

​​@@Phrewthat literally has nothing to do with the rumble sound caused by the unequal length of the exhaust header. The Shelby gt350 is a flat plane v8, but it doesn't sound like a flat plane v8 because they use unequal length headers.

[@hugacreeper69110]

This has to be one of my favorite toyan models! I own the first FS-S100A and it still runs amazing after almost 3 years.

[@TheUncleRuckus]

I believe the reason the fan broke is bc if you look @6:18 you can see that as you rev the engine the fan belt starts expanding quite a lot, I'm sure the belt came off the pulley and got sucked into the fan and caught between the fan blade & shroud. I miss this kind of content, while I like seeing these different engines being run its nice to see them do some work rather than just a static run test. Hoping for more videos like this in the future! 👍👍

[@liamm-c1287]

Looks like the air cooled 911 look. Would be sweet to see a flat 6

[@aserta]

Rather than metal rings, probably would've made this work with teflon ones. It rides better, seals better, doesn't wear as much and there's never enough heat in such an engine to touch the teflon. Back in the day, it was my favorite method to make a very long term flying (endurance race) RC. Also, they keep using flat pistons, but just like the real deal, shaped heads have better ignition, heat distribution and compression.

[@Weezel13]

This is what i missed, doing something with these engine builds! I love watching your modifying and/or use of these engines in something other than a static display. Looking forward to "something larger is coming!"

[@ichosolemanuel6048]

Ikr theyre so cute especially the overhead camshaft was so small!!

[@produKtNZ]

That is one of the best sounding engines out of the box !

[@kozapytapl]

i was just thinking about setting up a somewhat bright nightlight in the bedroom, h7 seems like a good idea but i didnt know how to power it without some awful power adapter. this seems to be the perfect solution, the wife's going to love it!

Absolutely beautiful piece of engineering.

[@julihermes]

Imagine a miniature VW Beetle with this engine, so cool

[@TailSpinRCSpain]

My first thoughts exactly !

[@Nordlicht05]

Dune Buggy with visible engine.

[@wedgie502]

it would be awesome if you could also get the "tweet" note out of the exhaust!

[@albinklein7680]

It will never be a Beetle because this is not a Boxer engine.

[@wedgie502]

@@albinklein7680 The boxer engine is a flat engine, belonging to the type of internal combustion engine. The engine pistons are arranged horizontally and symmetrically on each side of a central rotating crankshaft. When operating, they move continuously and in opposite directions, transfer force to the crankshaft, helping the crankshaft to move. It’s called “boxer” because the way the pistons move is like a boxer throwing punches. You have just learned something today.

[@yahaaa1343]

So hype for the coming dyna ! Thanks for the vid.

[@7.12_am]

This guy is going to aquire all possible knowledge of cars and build us the ultimate RC vehicle no DIY person has done before

[@NeoIsrafil]

This thing is just the ultimate cuteness! I'd love to see you hook it up to a car or rc truck and see how competitive it is. Flat 4 and 6 engines are such runners...

[@sibusisosising8112]

Thank you man for this awesome history about out sports. Will be waiting for for. Thanks once more

I wasn't expecting this a flat 4 miniature engine. This is interesting.

[@JazzbLu]

Alright! You are making a dyno!! I love your videos!

[@arnaldorentes5371]

[@evilbeetlekustomscreations4965]

😮😮😮 I know what I want for Christmas

[@davidattenberg4720]

Nice kit

[@aserta]

4:37 could probably make a quick and dirty C shaped cradle that goes in that gap and hugs the crank case, affixed in place with the existing leg bolt(s). From it, simple flat legs could come out that later could be engine mounts (for example). You could use the rubber isolators used for radios, test equipment (you can find them online with "vibration isolator electronics").

[@mars7786]

The mini motor master back at it

[@Ist02]

This Chanel is amazing

[@benjaminmathon7417]

Good call on trying to find out power output, you can always improve it in the future, with big resistor for exemple and trying to find out the efficiency of the system On the Toyan FS-L400, same number of cylinder, fuel and displacement, they give the power output of 3.05hp, so 2200 watts... yeah, right...

[@egoalter8745]

This is very cool video and engine.

[@jay7264]

Love the generator idea. Make it so it can be used to charge a car battery then run an inverter off it so you can run stuff in an emergency

[@jakhazardzn9862]

[@microbuilder]

Hey if you didnt see it, on the Adam Savage Tested channel, they recently went to a makers fair and were showing some pretty amazing little engines.

[@RoMiguens]

Relly has good footage and an excellent "dyno setup" Well I sort of talked about that idea 9 months ago, in a coment I made, a bit tricky but very nice. I'm an electrician and we use dry resistant or a dry generator coupled like that set up for engine-generator tests and it's good to test temperature and horsepower/ consumption. Just need to make a conversion on the load/ Jules/power output/ time. You have charts conversions online. Very nice 👌

[@HakkiOgrt]

Yeah I noticed when you put the timing belt on after tightening it the crank mark was out by one tooth. 3:57 it moves after tightening it

[@fyrbyrd71]

Yep. Watching in .25 speed @ 4:00-:03, the cams both move with "left" cam moving the most. The timing marks should be more precisely located and indicated so all builders can get valve timing right the first time.

That is so crazy... those piston rings tho... does the gap close up? they seamed to have an awefully big gap in them... So amazing how it is a REAL ICE and has a lot of the exact same componants, just shrunk down!!! I get so amazing watching these and would love to own a bunch of these myelf, but this would be a hobby that got out of control and my wife would kill me for spending that kind of money on a small engine, LOL.

[@buildingracingvideos4714]

That crank makes it a 180° v4

[@volksdude1970]

I was trying to figure out whether this was a VW style boxer, or the "modern" Subaru boxer style. After seeing the overhead cams, I'm thinking the model designers decided to take a bit of both and build a Frankenstein engine of the two. It's "technically" an air-cooled Subaru, but I could be wrong.
