Flame outs
 

Ok this is weird.

Ofcourse every now and then we get flame outs. But was causes them.

While running recently, I had about 5 flame outs. Each time, I was I was involved in a bump or a spin. I was spun around twice. Flamed out both times. I cut a turn to tight, ran over a corner dot spun and hit a rail, flamed out. I got rear ended, flamed out.


Anyone with some experience help out with a answer here?

Flame outs
 

the reason y flameouts occur is because ur engine is too hot so it shuts down! so its most likely i think ur too lean! or rich i forgot which one was the one where if its too much its bad.

whats a flame out

Flame outs
 

My temps were 210, so I must have been a bit to rich

Flame outs
 

I think that a hard bump or spin causes the carb to not atomize the fuel and drip it instead. Not completely sure, but it would make sense.

Flame outs
 

same here.. have no clue what that is..

Flame outs
 

It is when some unburned fuel/air is shoved out the exhaust and innites in the header/muffler. Or the fuel is still burning when it is forced out the exhaust.

Flame outs
 

mate this aint the fast and the furious and you have no spark plug in your exhaust

work it out so i can make flame outs

Are they the same as backfires?

and could it be a faulty glo plug?

Change your glow plug - That will solve your problem.

That happend to me and teh glow plug change made all the difference.

Damn, why can't I flame out?

Adjust the exhaust to point the right way and I might be able to stop them little kids by us from pissing me off... :D

Guys - you have it all wrong here...a flame out is something you -DO NOT WANT.

It is not when a flame comes out of your exhaust. It just means that your engine was running so lean that there was either no fuel left to burn in the engine or no lubrication and it seized. If you have a bad glow plug your engine may stop upon slight impacts or turns but that is fine. Flame outs occur mostly on high speed runs.

You will not be able to get flames to come from your exhaust - sorry to dissappoint you.

Wanna bet?

*goes hunting for the smallest can of butane he can find*

Mwuhahahaaaaaaaaa

;)

yea exactly! the other kind of flame that comes out of ur exhaust(like in f&f) is called flamethrowers! lots of muscle car people do that too! they have comps for this too!

Flame outs
 

Like what Lumburg said, it is too lean on the low side.

Flame outs
 

A flame out is any time your engine stalls. It could be from being too rich or lean. The most common cause is when accelerating an over rich engine the glow plug is cooled too much by the excess fuel and stops glowing, the engine stalls and thus the term flame out. :cool:

Flame outs
 

are there such things as flamethrower kits for r/c cars?

Flame outs
 

yeahz its called duck tape a liter on da back of your truck, then duck tape a spraying bottle of starter fluid down behind da liter, tape da liter on so it flamez and drive

Flame outs
 

And while you're at it, swallow a bottle of nitro glycerine and jump up and down really quickly :D

Flame outs
 

During the combustion process the flame front propages and consumes the burnable mixture, thus expanding the heated gases which push the pistion down to transmit mechanical energy.

When you're lean, you'll start to detonate (multiple flame fronts and basically an explosion rather than a combusion). If you're really lean then basically you'll just be heating up air because there's not enough fuel and that basically will get you no where. I guess this could be considered partially as a flame out.

A flame out is when you run too rich, thus fouling the plug and robbing it's ablility to stay hot. Therefore you will not have a source to initiate the flame front, hence 'flameout'. Too rich of a mixture will douse the fire.

if thats what it is stop calling it FLAME OUT and start calling it munted settings.

Flame outs should involve open flames and yous are destroying my mental pictures.

some real flame throwers work by causing some cylenders to not fire (ie cut spark) so the fuel mix travels out exhaust. then you have spark plug in exhuastpipe to ignite this mix.
but you need to buy a computerized thingamy to make your engine missfire (properly).

Either that or drive a ford fiesta...

Re: Flame outs
 

If I read the original post, it said that each flame outs was due to a bump and spin. To me, the car was running (throttle up) and then the bump spin made the driver let off the gas (throttle down). When the LSN is lean, the flameout or stall will occur as if you went from WOT to idle.

If you go from idle to WOT and the engine stall, it is more likely that the HSN is too lean.

I don't know about the rest but the term "flameout" in this case is the proper lingo in r/c and is understood by most of us (rcers).

Flame outs
 

Seriously at least get your terminology right. What you're looking for is a 'backfire'. This occurs when a rich mixture bypasses the combustion process and remains in the header(s)/exhaust piping until a flow of superheated exhaust comes along and ignites it resulting in a fire racing out the tail pipe.

This is exactly why I don't condone the movie FatF. See what it does to our society these days?! Yeah fire out the exhuast is really cool!? :rolleyes:

I just love all of the miss informed ppl on here, first of all with the flame throwers, how it works is you need an engine that is carbed, and you need to have a choke, and you basically have a switch that switches the spark coils from the 8 plugs to the ones in your tailpipe, while doing this you choke the engine and it essentially stops firing and sends fuel/air down the pipes, the engine keeps spinnign just with no spark, and you cycle this. no fancy computers needed at all, now if you were able to get a small spark plug into the exhaust you wouldn't need to kill or choke the engine cuz a 2 stroke engine sends so much fuel out the pipe anyways that there is a sufficient amount to ignite, i found this out when i was building a muffler and test ran it with tack welds, then went to complete the job and even after 5 mins of not running there was sufficient flammable gas in the muffler to ignite and make a small fireball.

first, I think he is talking about stalling the car. flameout is usually used in jets for when the fire goes out in the engine and you got no more go.

second you dont need a switch or a spark plug in the exhast to get fire out of the pipes... what you need is a hot rod (ie a nice hemi dodge)

rev the sucker and take your foot off the gas. now what happens is that the engine is sucking more fuel then its buring and raw fuel is going into the exhast.

if the exhast is hot when the fuel hits the air you get flames.

now alot of show cars will have spark plugs to aid the ignition and some even have fuel injectors in the exhast (either gas or more commonly lighter fluid) or spray bars at the tips.

one show car here in NJ has the spray bars and can shoot flames 20 feet out the back. its an old chevy or something (cant remember the model or year...56 maybe?) but its white
