WOW what a fire
« on: October 15, 2014, 08:31:43 PM »
I was getting my Infinity ready for the Baton Rouge contest. The airplane is three years old but an outstanding flier. I had just installed a new Berger motor, controller and six cell battery. All was looking good, the new battery installed and ready to go Well all that was left to do was bolt on the bottom cowl. So I put it in place and put the rear bolt in .I then installed the wrong 4/40 bolt in the front hold down. Well it was a little to long and went into the battery. O M G the noise and smoke was something else. I picked up the airplane by the wing and set it next to the pool and got back. No way was I going to get close to the inferno. I went into the house to get my wife to look at the burndown from a safe distance. Well the battery just burned through till it dropped to the ground. The next day I took out the motor and it might be OK but the controller is junk and the front of the airplane is gone from the wing root forward. All because of a bolt that was one half inch to long.. Live and learn.. Bill

That reminds me of the time I was starting my Madewell 49 on ignition in a Yates Dragon. I was using glow fuel. The engine was flooded and went "Bloop". And then I noticed that the paint on the side of the fuse was starting to bubble up. You just cannot see an alcohol fire in the sunlight. Just the results. At least yours smoked.

Rule # 1. Never let the smoke out of any electrical circuit. It's real hard to get it back in.

Was the battery covering particularly soft?  Or was there an exposed portion of the cell, meaning it didnt have the factory shrink wrap over it??  It seems like you would have felt the 4/40 bottom out against the battery before it punctured the covering?  What kind of battery?

What it says is that improper maintenance procedures are dangerous no matter what the mode of power...

I'm certain that my old good buddy, Bill Rutherford would wholeheartedly agree with that statement. He's a full-scale pilot and FBO operator. In that world a mistake in maintenance could kill you. I salute Bill for his honesty in telling his story. He could have just kept quiet about it. He decided to use it as a teaching lesson for others.

To answer Doug Moons question It was a brand new thunder tiger 6 volt 3200. There is one hell of a lot of power stored up . When it lets loose look out! I thought about sticking it in the pool but that would make a real mess.
     It reminded me of a B29 that landed in a lake way up north in Alaska or Canada. These guys pulled it out of the lake and rebuilt it Changed engines and all that. Well they were about ready to fly it out , now there is snow every where and their filming the whole thing. They start the APU and it runs fine but it was not secured and it vibrated and broke the fuel line loose and it started on fire. There was nothing they could do so they all sat on folding chairs and watched it burn to the ground. There was no sense trying to be a hero and get burned or killed. Just accept it and watch all those years of work and money go up and smoke. Yea , I thought of that and just watched it burn. I should have got my movie camera and filmed it. Well next time I'll do that. Wait did I say that

Been there, I wish I could get my wife to tell the story how I had rebuilt my old school Triumph Bonneville chopper, new paint and all, brand new springer front end and king/queen seat. When I fired it up it was backfiring through the new chrome scavengers, so I asked her to hold it up till I rotated the timing...she was on the left hanging on to the 6bend pullbacks trying not to drop it, I was on the other side moving the points backplate with the motor running....she was pressing her knee under the new fiberglass tank when it popped out of the rubber mounting and the fuel line came off....about then it backfired. I sat there watching it burn up 2 gallons of gasoline, the new tires, the new battery and the new tank; all adding to the black smoke.....dang near cried! y1

It seems your "R/C Buddy" is a bit of an alarmist. There are tens of thousands of modelers (probably more like hundreds of thousands...) world wide using Lithium Polymer batteries who have had zero issues with them. Of course they follow safety procedures, charge correctly, and store their batteries correctly. There are also modelers who fly glow who have had cars and houses burn because of improper safety procedures.

I've been flying electric models using LiPo batteries since 2005. I have not had even one issue where a battery vented. However, I'm fully aware of the possibility of such an occurrence and take all necessary precautions. In fact, the only issues I've ever had with fires were when using glow engined models. That was way back before mufflers. And, in the past I've read about glow fuel cans exploding in cars. That didn't stop me from flying with glow engines and glow fuel...

Here's the bottom line: Electric models are here to stay, and they will continue to increase in popularity due to their many advantages. They are inherently no more dangerous than glow models if all the safety procedures are followed to the letter. LiPo batteries do not "explode." They can, however, "vent with flames." To prevent this venting, follow all safety procedures and you most likely won't have a problem.

It seems to me that all of the alarmist posts about LiPo batteries are coming from people who have never actually used them. Bill's problem - BY HIS OWN ADMISSION - was a mistake made by him. He ran a screw into a charged battery. That was not a problem caused by the LiPo battery; it was a problem caused by inattention to detail. And, again, Bill was enough of a man to post about HIS mistake in hopes that by doing so the rest of us might avoid that one ourselves.

I've read many posts on this forum that are nothing more than thinly veiled attempts by those who prefer another power mode to try and hold back the proliferation of electric power. Get over it! You are embarrassing yourselves. Have you not noted that those who fly electric are not attacking your preferred mode of power? We could care less if you fly glow, electric, steam, nuclear, or use two chipmunks on a turntable to turn the prop (s) on your models. The electric versus glow debate at the Nats is no longer happening among the top competitors; they have come to accept that there are at least two methods available that work at the very highest levels and have moved on like the gentlemen they are. Can't the rest of our modeling community do the same?

Alarmist posts such as yours, John, only serve to scare those who have no real information. It's funny how those who don't want to use electric power appear to be campaigning against it instead of just not using it themselves. Kind of reminds me of the relative approach to life choices by the two major political parties... The members of one of those parties feel that if they don't like something, then no one else should be able to do it either. The other party's members feel that if they don't like something, they just don't do it, but don't feel compelled to try and outlaw it for others. It's called freedom...  

Now, those of you who are concerned about fire, "flame away" at me. I've had my last say on the subject.

I have known some RC people in the past who kept and charged their LiPo batteries in an outbuilding out of an abundance of caution.  This was in the earlier days of e power when I belonged to a club.
Batteries may be better now, I don't have LiPo and don't know.  When I finally use up my substantial stock of fuel, I guess I will either have to go electric or quit.  Glow fuel is not obtainable around here any more since Fox quit.

Thanks Bob for your comments.  I now wonder if there was this much trouble when gas power was introduced into  free flight.   Also when glow plugs were introduced to replace ignition.  And a word of caution if you are flying a rubber band launched glider have a good hold on the stick/rod.   Any form of personal intertainment can be hazardous if procedures are not followed.  Thanks again from the old DOC.

The thing to remember is that we are all fallable as Bill found out. It reminds me of a story about my former boss and friend. He was a great deer hunter and when people were complaining about hitting deer with their cars he blamed it on the drivers just not paying attention. One day he got particularly strong on the fact that people just do not know how to drive or they would not hit deer. The next day he was late for an appointment with me and I asked him why. He sheepishly told me a deer came out of nowhere and he hit it.

Sounds like me!  LL~ LL~ LL~ I used to say that if people wouldn't speed, they wouldn't be able to hit deer. And Truthfully, I have asked everyone I knew that hit one how fast they were going...most just said too fast. LOL Then one day I was driving down a gravel road about 25mph when wonder of all wonders....a deer ran into the side of my truck!  ;D

I'm not the alarmist you think me to be, Bob; I was trying to get him to sell me some of those new batteries when he told me that. I think he just wanted me to buy his old stock of NiMH batteries. He was using the lipoly batteries at that time and told me that my chargers would not be wise to use on those. At that time, I didn't particularly want to buy chargers, so I shut up about it. I'll try from now on to stay out of private threads. H^^

The chargers and their fail safes that have made things much safer.  I know many RCers who feel the same way as posted above.  But they were using Lipo before we had extremely reliable chargers that wont let you, or almost wont let you, charge things incorrectly etc...  They have a good deal of fail safes now.  But at any rate one should always take caution and understand what they are using and pay attention to detail.  I use very large Lipo in my helis and charge only when I can be around.   

It sucks that Bill lost his plane and at the same time it's great he ONLY lost the plane.

I charge my RC lipos on the stove (HAHA I cook them for good!  Really, the stove is heat proof, somewhat ventilated, and can be taken apart hot.)  I have lipos in my phone that gets charged on my nightstand.  My laptop has lipos.  The technology is everywhere. 

I can say there is a need for "screw shields" in a number of designs.  How about a cut up plastic bowls or aluminum flashing with some double sticky to the back of where the screw comes through.  Running a screw into a battery is no harder than running a screw into something else it ought not hit...
