..........I take the glow starter off?? I am talking about my Raptor 30 v2. It has an OS 8 plug in it which is brand new. It idles good until I remove the glow plug adaptor, then it stalls. Not too sure what is going on here. I have the carb on the settings that it shows on raptortechnique also. Could it be that the engine is too cold. I have it in our garage and it is kinda cool in there. Not sure if that would have anything to do with it at all. Thanks for the help.

It runs when the glow ignitor is on, but dies when you take it off...I have no personal experience with nitro engines, but I have been reading rc car action and rc driver magazines since january of 2006, and have seen this question several times. They always give the same answer, the glow plug. I would try a different plug. The one you have in it may be faulty, even though it is new. If you are worried about the temperature, you can use a hair dryer to heat up the cylinder head before you start it. Seems like if it was the carb settings, then it wouldn't run at all. Hope this helps, if it doesn't, I tried. Maybe someone else with a little more experience with nitro can shed some light on it. I will ask around the other forums and see if I can get a better answer. Peace.

Never mind, just saw your other post. Glad you figured it out. Info for the future, cause I am going to get a nitro bird some day. Peace.

Bug, not to pisss you off because you meant well but wy answer if you have zero experience with this type of a problem? Or even experience with glow motors at all?

low end is too rich

Ah, you're one of those that thinks just because a person hasn't done it, they know absolutely nothing about it. I bet you sneer and laugh at beginners when they try something that you consider easy and spread their craft over the ground. Just an ASSUMPTION, which it seems you have painted me with. Not to piss you off or anything. I have been considering getting a nitro driven vehicle for some time, and knew several people that had them. My wallet isn't big enough for it yet cause I can't get a job where I am, but I have been researching how to tune and maintain nitro engines for over a year, and saw the same problem in several different places. Their answer was always the same, the glow plug. I was simply passing on info from someone that did have experience with them. I also just added two more pieces of knowledge that will help when I do get a nitro machine. JoDyO figured it out, it was his ignitor not heating the plug properly because he had accidentally left it on the engine and melted the end, and Cambo's answer set me straight about carb settings. Now that I think about it, that makes sense. If the low end is to rich, when the ignitor is taken off the fuel cools the plug to quick causing it to stall. A person with the whole "if you don't know for sure why bother" attitude keeps people from learning, and only helps turn people away from this hobby. Don't be that person. Peace.

I guess I pissed you off, sorry. I thought I was wording it in a way that wouldn't. It's just when you preface your reply with having no experience to a person that does and has run out of ideas I don't see them taking your information seriously. I am not trying to get into a pissing match and deffinitly don't want to make you mad but experience counts for a lot, you can't read your way to knowing how to do something. Reading helps but you have to get your hands dirty yourself, not even watching people do something will gain you all the knowledge.

As far as helping people, I do, alot, look around on here and you'll see it and that doesn't count the real help that I give people in the club I'm president of.

There is actually two reasons why an engine would not continue running after the glow driver is removed:

1. Low end too rich
2. Possibly a fouled glow plug.


Both of this reasons had been convered before. I thought that putting them together will actually help.

Raf, make that an engine in good condition with fresh fuel and .... as there could be many more reasons.

Actually there are a lot of reasons, engine conditions, old fuel, filling the muffler with fuel when he fueled the helo, either end not carbed right... And the enfine in good condition can include bad bearings and the front bearing seal, a number of carb issues, loose head screws, glow pug, and backing plate screws.... alot of things.

But the original poster had already found his proble by thesecond post here on this thread so it didn't matter. I probably shouldn't have posted and let this die but I was curious why Bug answered, nothing more, and I pissed him off. Luckily he has thick skin and can take it.

Well, there could be a whole list of reasons why an engine would stop running.

But assuming that the engine is healthy, because it was already running with the glow driver still attached, those are the two main reasons why it wouldn't stay running.

You are right, it is just that with the information provided, there are a whole lot of assumptions that have to be made. We don't even know the brand and model of the engine. All we know the glowplug is a no. 8, about the standard plug for a helicopter engine.

About the "other thread" I have no clue on what you guys are talking about. I seem to recall a thread about a damaged glow plug by the same author, but then I have to remind the author to keep the threads to one. Multiple threads just add confusion.

Raf, where is Junction City? I go to Grand View south of K.C. quite a bit...

Junction City is about 1.5 to 2 hours (depending on time of day and driving speed ) west of KC on I-70. If you know where Fort Riley is, Junction City is right next to it. 20 Miles southwest of Manhattan.

You coming this way sometime? I'll love to have a heli flying buddy sometime. Right now I'm all alone, the other guy that used to fly here was deployed to Iraq. There are a few people getting into helicopters, but there is nobody that I can learn anything from.

From time to time, I meet the guys in Topeka (about 45 min to 1 hour west of KC) to fly at their field. There are a couple of guys there that can do some stuff that I can't so I like to hang out with them so I can continue learning.

Rafael

I'll be there, KC, the 3rd and 4th but won't have any extra time plus it'll be too cold... maybe in spring I can schedule an extended visit....

Man, that kinda makes me want to stick with electric...kinda. It will be electric for the helis, no doubt. These things are frustrating enough without the added hassle of nitro, but I still want a nitro vehicle cause there is nothing cooler than the sound of a big monster truck catching second, then third gear while throwing foot high rooster tails from all 4 wheels, or watching a 4-tec 3.3 catch second and scream past 70 mph.[X(] (I'm a car guy in case you can't tell)
Hahahaha!!!! Yeah, I can take it. I can also give as good as I get, or feel that I am getting. I just seem to feel I get it more than I actually get it. People also usually respond with much more specific answers when I do that and that is just more info for my future endeavors...not that I go fishing for that kind of thing, cause I really don't...not consciously anyway...maybe I should see someone about that.
