Before I go that route, any of you guys got a neat, tricked out container for haulin' your LiPo library around in you'd like to showcase for ideas?
Ah another Geocacher. The miles I have done chasing around the UK just to find those 'Tupperware' boxes.
My Lipo storage boxes. the one on the right is what I take out with me.
The one on the left is a fireproof document box.

Don't forget that if you use Ammo boxes you need to remove the airtight rubber seal.

There are more threads, and more differing contradictory opinions than you would ever wish to read on the containment of LiPos, but one thing that seems to have been fairly well agreed over the years by folks who actually know what they are talking about is not to store them in an airtight metal container.

If they ever do go up it becomes a very nasty bomb. You cannot contain the pressures generated in a major LiPo fire with normally available containers, including fireproof safes. You have to let them vent and put up with the smoke. A vented Ammo box will contain the fire however.

Replacement unit could be either V1 or V2 (presuming V2 would fit) -- anybody know if BH or anyone else EVER has the replacemnt pars available, as their web-catalog says? Wouldn't mind having an extra wing set to tinker around with, either.

SH,

You can buy spares at BH

I think that we get paranoid about the danger of lipos. OK I know in our hobby we do at times abuse them, but with care we should not have to worry.
There are now many devices that use lipos as their power source, and the users of these do not worry about them.
As for storing in air tight boxes. I would not put a damaged or suspect one in one, and I don't think anyone with half a brain would do so.

Poppa, generally I agree and I don't want to start yet another LiPo safety slanging match. LipOs in practice are a lot safer than the panic merchants would have us believe but they are still potentially dangerous, they have caused (sometimes delayed) catastrophic fires and there are three points we need to remember.

1) The analogy with other "devices that use LiPos as their power source" overlooks that fact that those devices normally have safety circuits built into the battery pack (which is often a safer variant of Lithium technology in any case).
2) Other users do not draw massive currents at the limit of the C rating of the technology from uncased LiPos which they then launch at high speed into the air, on occasion returning at high speed from said air - except for the last inch.
3) There is enough evidence on these forums (and certainly on YouTube) that some people do not pass your last test.

My point about the post was that many folks might think intuitively that putting them in a sealed steel container is intrinsically safer - it isn't.

Enough OT discussion. Back to Bixlers.

I think that's a worthy tip, thanx.

That's a good idea.
I seem to remember aj was using one of these.

Gee, didnt think of it and still have the rubber seal in there.
What about drilling small holes?

AJ
P.S. Did the plane present any flying differences with the leds? (i.e. Lift and drag changes).
It flew like a fat pig -- I should weight it -- but it's heavy. The lights on the wings are just mounted on top facing into the wing.. I had them on while mounting so they could be depressed into the wing, and covered with extreme tape. The blue lights were inside the fuse -- I split the fuse and installed them then closed it back up---I'd have faced them out through the foam -- but I wanted a uniform glow. The white lights are mounted facing out -- those on the fuse are recessed and covered with tape.

I'll shoot some pics of the mounting later on -- not very pretty -- this one is my beast. My family now has .. lets see --- wife's Bix, son's Bix, my training surfer, my night surfer, and my camera bix. I guess that's 5 -- with one kit waiting as a replacement.

I say it flew like a pig -- but really the wind was so high last night that it's not a fair assessment. I normally land at my feet -- but due to the wind and the many people watching including small children nearby (but not on the field) I landed about 200' feet away. -- but it did require 1/3 throttle pretty much full time -- however launches were uneventful -- so I guess not THAT heavy.

I'm hoping to get video tonight. Forecast is for very light wind.

It was definitely a crowd pleaser. -- especially when I flew over and flipped on the white lights the first time.

Should work. I am sure there will be several ideas on the forum on how many and what size they ought be and if it is a good or bad idea. If you want to do a search on safety/storing/LiPos there are plenty of different opinions - many unencumbered by associated evidence.

The rubber seal is dead easy to pull out with a pair of pliers though. Down side is that the latch no longer holds the lid on as securely.

I added 240 of the HK strip LED lights. Plane turned into a porker at about 32 ounces AND it was tail heavy with 2200 3S shoved in the nose. After the equivalent of 2 quarters added to the nose all is good.

Well, I could leave the sections of the rubber seal inside lets say around the corners so it has some tension and would not come out.

These photos were taken my my lovely bride who proudly flies her Bixler whenever time allows.
Scotty - that thang is WILD! And I'll tell ya what -- if either was me in that photo of Nick's hand launch, that one would be going up on my wall, poster-sized!! Great shot there.

Got a 'failed camera' story for ya. Me & a couple van-loads of family went down to Canaveral to watch the planned final launch of the Shuttle Atlantis - & I borrowed a GOOD vidi-cam from a friend of mine....none of this keyfob kamkrap or my HD Vaio (which I hadn't yet bought at the time....which I did because of this episode). Fought & weaseled my way right down to the water's edge at SpaceView Park, & shot a ~3-minute 360* panorama of the launch pad complex & surrounds, & the mob behind me, & shut it off. While we were doing that, another in our party had gone exploring & found a place with a better view & a whole lot less crowded, so we hoofed it over there, about 1/4 mile away.

Got all set up; tripod mounted, pre-programmed flight path & clutches all adjusted good to go. At T-20seconds, cranked 'er up & hit the GO button....and its batteries were deader'n Gene's heart LiPo pack. And it had spent the night on the charger - pulled off just before we left the motel.
Talk about Paradise Lost! The beautiful Florida sky was a good bit bluer by the time I got done telling that camera what I thought of it!

Thank providence I had my cell-phone cam at least. That's all we came away with besides some great memories! Here's a still from my family's forum home page:
