V12 fits in the palm of your hand
 

nothing sort of amazing if you ask me

im just wondering what kind of fuel these guys use when they build such small engines seeing as how there is no apparent source of ignition other than compression
i could be wrong

but dont those rc cars that use nitro or whatever
dont they still use glowplugs?

anyways
watch the vid on the link
it is six minutes long
it shows him machining and assembling the engine

edit:
does anyone know spanish or whatever language the subtitles or whatever in the vid are? there are a few things on there that i would like to know what they say

Thats fucking awesome, thanks!

i think it would be cool for a rc lambo or something

Most model engines are run on Coleman white gas or equivalent. And yes, they have an ignition system and plugs like a full size engine. Usually it's hidden in a base, because the coil has to be fairly large (can't be miniaturized). This one is run strictly on air.

This particular engine and video have been all over the model engineering forums. It even impresses the hell out of guys who've made their own V-8 engines, mostly because of the super precision fits on the mating parts. He made everything, including all the fasteners.

someone get this guy a job at ferrari! 1200 hours to build that, insane but I believe it

WTF? He did it BY HAND?

I'm amazed.

Amazing. But this guy must be the most boring man in the world :)

j/k joe :makeout:

Yeah kinda like that guy who built a scale replica of a ferrari 312PB by hand
a working flat 12, transmission suspension etc.
20,000 some hours. Now that guy was crazy.

I need that to be in my xmod.... stat.


Awesome vid.

Does it run on Megasquirt?

:bowrofl:


can someone link me to a good 101 infro on these kinda motors
there gotta be kits right?
i wanna check em out

Holy shit O_O that's awesome. The titles are in Spanish. They just simple list the procedure that is happening on the video. Goddamn that's talent.

Not kits, but raw castings. Lots of plans, too. It's actually easier to make from bar stock, as this one was. Search for HMEM, and it will take you to a forum where all we do is build tiny engines. I've been doing it for years, and I'm nowhere near the level this guy is.

There's air powered (easiest), and you can run most of those on steam (messier). Then there's the hit-n-miss style, and then the scale V-8 and radials. Small scale V-8's are popular, but can take from weeks to years of work. And that's if you don't care about scale, but just want a runner.

Loads of videos on utube of all sorts of engines. However, as far as I know no one makes a simple bolt together kit. You gotta make 'em yourself.

haha with the music i kept expecting some disney character to pop out of the engine or something...
but yeah pretty amazing stuff there..

Cool video! Conley V8.... if i remember correctly sells a v8 kit. I could be wrong tho.

Its amazing the things people can accomplish with shitty tools and a lot of time

I would turn my nose up at a goofy little lathe like he was using, yet Ive never built an engine from scratch, haha
