RE: delete
And not one fire extinguisher on site.[X(]
You are questioning a static charge. Could it have been a shorted out battery. |
RE: delete
ORIGINAL: Dixty .. make sure you ground the jet <u>before</u> touching it.... ?how i can ground the d@m thing with out touching it?:D |

Except for the fire extinguisher under the table, which nobody grabs! [:@]

In seconds 218-223, you can see clearly a FIRE EXTINGUISHER under the table.

on watching it again, there was a fire extinguisher under the table. Missed it the first time.

the fire ext is under the table not more the ten feet away. The proplem is the did not have it at the a/c |

So you just joined RCU and this is your first post??? What is your modeling experience? It looks like you're trying to be an alarmist and don't have much knowledge of model jets.
There is no evidence that the RC jet fire in that video had anything to do with static discharge. It is not as big a concern as on full sized aircraft. There have been some ECU problems blamed on static electricity, but I have never heard of anyone blaming a model fire on static electricity. |

The fuel tube that we use is not rubber its the same tube the gas guys use and the same tube is used in weedeaters and some lawnmowers

The video is almost a year old and has made the rounds on RCu a few times. Not sure where you are coming from (or trying to go) with this. I would have to put the total number of spontaneous combustion occurrences from touching jets at negative one (-1). I have actually seen -1 of them.
Now for some advice people CAN use. Do NOT use your jets at a BBQ. No matter how good the carne asada from Dougy is, it is NOT worth lighting your jet on fire to cook it! well, maybe just a wing or something :) Chad |

Dixty: I suppose ur heart is in the right place, that u mean well, and u just want to make a meaningful contribution to the hobby. Good on ya for all of that.
It's a shame to see u attacked for trying to help. But... surely, if this were a valid issue then we'd also be hearing about it from the gasser guys because gasoline vapors are so much more volitile. Or the tons of very, VERY experienced folks in the jet side of the hooby would have stumbled across and recognised it before now. Many of these folks have extensive aviation backgrounds and the concept of static discharges is not a new one to them. And I can't remember anyone ever mentioning being "electroshocked" by a model of any type. Never say never...but this threat just doesn't seem to be a "thing", ya know? Thanks for trying tho......... |

THE FIRE EXTINQUISHER IS IN PLAIN SIGHT !!!! WHY DIDNT ANYONE THINK TO GRAB IT?

RE: delete
Over 1500 flights of non grounded jets at KY jets. Not one fire caused from static. This is bunk. I've never once heard of a jet catching on fire from not being grounded.

Yea, and just like [link=http://www.youtube.com/watch?v=ZlCLuIwuVgQ]Eminem[/link] says, [link=http://www.youtube.com/watch?v=2rhPux0EIPA]"I'm not afraid"[/link] of any of my jets catching fire, because they're always grounded anyway, especially when I'm not flying them! :)
Now on a more serious note, I have always seen a grounding wire connected to real planes when fueling/defueling, but what do I know, I just stayed in a Holiday Inn Express last night. :D |

RE: delete
ORIGINAL: joeflyer The difference is that with our models we do not pump enough volume of fuel at high enough velocity to build up a significant static charge. Awww man, see that? [:o] All this time I've been waiting for Tamiya to come out with that big fuel truck with the six wheels on each side that holds 5 gals of Jet A so I can get some realism points with a miniature static grounding wire! :D ;) |
RE: delete
Ok... tell me this.
How are you going to electrically "Ground" an airplane when about 90% of them are made from foam, fiberglass, and balsa wood. The only things that conduct electricity anywhere "decent" (besides the electrical stuff and metal parts) is the carbon fiber in the airframes. But those are not really oriented to build a "common" ground plane that connects each piece of carbon to the next. Most of the tanks are mounted to Wood structures.. last i checked wood SUCKS at transmitting electricity. Rubber/ tygon/ poly tubing isn't exactly the greatest either at transmitting electricity either, which is what most of us use for fuel and air lines.. Good intentions are probably intended, but its not just as simple as putting an alligator clip to the airframe with a copper wire going to a ground "stake" in the ground. Not to mention in the full-scale world, grounding of the airplanes during refueling is done b/c they are pumping fuel into the tanks a hell of alot quicker than we are, so they have a higher chance in building a large electro-static charge. |

RE: delete
what really gets me is that in the video, the guy behind the camera focuses on the fire extingusher at 1.00 minute. Why did he say anything to the guys about that extingusher...... THEN look at 1:10, one of the guys brings over the fuel jug and attempts to defuel while the jet is burning.....................

RE: delete
ORIGINAL: Dixty Hello :D Ground the jets before touching them! =) When a jet is flying, it's hitting air molecules... it's rubbing against the air in other words.

Mark Seen this happen many times over the years. Sometimes guys wouldn't even bring the fire extinguisher from their car or to the field at all. I would always make sure to go get mine or walk over and stand by holding it when I would see this sort of thing developing. Bottom line, and biggest lesson from this video, ALWAYS have a fire extinquisher within arms reach of a starting jet and be ready to use it. Of course, many of us already know this, but unfortunately, there's a few who don't or haven't had the unfortunate happen to them yet. Stay Smart. Bryce |

Everyone in that video should have gotten a Darwin award. The only thing that could have made that video better is if the guy shooting it zoomed in nicely on the extinguisher and then turned the camera around so I could see the look on his face. Unbelievable!!!![:'(][:'(][:'(]

HI, This vid had a thread about a year ago that went a few pages, and it was stated by someone that was there that the fire ext. was empty from another fire. I can't see the guage but I did notice the hose is not stowed. Jets do make the best crashes and fires! cheers Tim |

If this happened in the "states" then i believe the waiver holder is a perfect candidate for a waiver removal

RE: delete
I was there during the fire. The fire extinguisher was tried but it was found to be NON OPERABLE. That's why no one grabs it under the table.

RE: delete
I wonder how many millions of turbine jet flights we had worldwide and only this one caught fire from a static issue and not something else???

RE: delete
ORIGINAL: invertmast If this happened in the ''states'' then i believe the waiver holder is a perfect candidate for a waiver removal Looking at article 24 and 25 of AMA 510-a, it describes the suspension process and that repeated suspensions may result in removal of the waiver. (Incidentally, you can still fly a turbine when your waiver is suspended and you don't even have to be on a buddy box you just need a to be under the supervision of an experienced turbine pilot). So it would appear that if you do something mind-bogglingly stupid, you could get suspended but not have your turbine waiver removed since there was only one suspension.

Read more: http://www.rcuniverse.com/forum/m_98...#ixzz0tud2Dtyl Our jets cannot accumulate enough static electricity to trigger a fire. Mostly because they are made or electrically inert material. I think that the author of this thread is mixing up real aviation ( aluminium planes ) with hobby ( wood, fiber, foam planes )... The only problem with static electricity in very specific cases ( very dry and dusty environment ) is the ECU watchdog triggering that might result in a flameout. |
