hey fellas. I was just curious what would be the smallest gas engine (doesnt matter 2 or 4 stroke). Nitro fuel costs so much these days and I am not so ready to switch to 1/5 scale toys. I realize that gas engine performance will be significantly lower than the same scale nitro engine but I would still love to know the size and what you guys think of putting the smallest gas engine on fairly large car (1/7scale or true 1/8 if possible).

.12 wont go fast but it is good on fuel economy

Codeblack

no fun

Codeblack

yea, or maybe even micro engines with .13cc...lol

I think he means gas as in petrol not glo fuel. 23cc is the smallest I can think of off the top of my head. I vaugely remember seeing a gas motor that was around 10 or 15cc but i'm not sure. Even the smallest would be a challenge to fit to a buggy.

Codeblack

I would be so proud to own one though. Ill try to find the smallest possible and if you have any links, PLEASE post! ill post anything around 20cc if I find.

Codeblack

and yes I do mean petrol

You can convert a normal glow engine to spark ignition and run it on petrol (gasoline). All the goodies needed to do this are available including the miniature spark plugs. You'd probably need to burn quite a bit of fuel to come out even on the cost of converting though .

Codeblack

lol, me and skotty were actually thinking of doing this a while back but backed out when trying to make spark timing work. You probably dont remember but it was back in that long nitrous thread when you measured glow plugs temperature for us . But what are these miniature spark plugs you speak of? Is it a full spark system or only the plug? I would really like to know because this way I can go back to that nitrous idea.

You could look into getting a 4-stroke nitro engine. They are more fuel efficient, and the sound is awesome.

I also found a 25cc 4-stroke made by Honda for strimmers. It's called the GX25. If you remove the fuel tank, cowling, etc. it should be as small as a 2-stroke. It uses less fuel than a 2-stroke and is more environmentaly friendly.

Codeblack

oooo, nice one Felix. 5 times bigger than my current engine but its a start

Codeblack

some weed trimmers have 14cc btw

ok, I can answer my own question now.. http://www.mecoa.com/compagnucci/index.htm

Lol the smallest Nitro engine I have seen is the .049..........and its 50 bucks at my LHS.............

Codeblack

HPI_Savage2514

I am not sure of the Brand...........but that name sounds familiar............

Codeblack

btw, do you guys know if COMPAGNUCCI sell that gas engine? I see only the actual rtr that has that engine in it..

VIPER458

yeah i want one too. i think itle just be fun to have it. it seems like it should be prety cheap bc the car isnt that expensive

SpikeX

Yeah, so do I. Looks like a good project, and IMO would be worth a try. If I do get it, I'll do a product review on it for everyone to see on my website (www.pxpracing.com), so you don't waste your money if it's bad.

Whydoncha ask your ? there ...

I know there are complete electronic spark ignition kits available...don't recall right off hand who makes 'em though...

You can convert 2 and 4 stroke glow engines...(I would think a ringed piston would be better that an ABC but? )

downunder

Yep, Cox .049 and there are millions of them around. But they also have the Cox .010 if you need really small . The next one up is the .020.....

I emailed Comanpagnucci asking where its possible to purchase their car gas burners, so ill post what they say. I dont think it should cost any more than a decent .28 ~$220
