Title: DS in the Dark

This is a short video of the first flight of my illuminated DS

(thanks very much to my helper for flying while I filmed)

That worked rather well.  ;)

I'm hoping things will go even better after I rebuild the lighting rig so that the battery doesn't pop out.

We did find the battery after a lot of searching on the beach. Unfortunately I didn't catch the moment the kite vanished on video...

Ha! That is very cool. I bet it would be fun to film it at a distance-- probably'd look like a UFO

Wow that's awesome.  Do you have details on your set up for those of us that have no idea how to do that ourselves?  :)

These are the current details - but I am rebuilding it at the moment:

The light rig is 2 x 1 watt warm white LEDs:

http://www.maplin.co.uk/1w-high-power-l (http://www.maplin.co.uk/1w-high-power-l) ... pcb-511367

powered by a lithium ion rechargeable CR123 battery:

http://www.amazon.co.uk/UniRoss-Sprint- (http://www.amazon.co.uk/UniRoss-Sprint-) ... B0008EI9WY

and a battery holder, some bits of wire and a couple of extra standoff fittings on the lower spreaders.

The whole lot weighs around 40 grams, with around 20 grams being concentrated at the base of the spine (battery & holder).

The amount and spread of light is good, making flying in complete darkness practical, and the extra weight doesn't seem to have too much of a detrimental effect.

Before the flight, I ran the rig to see how long the lights would run on a full charge of the battery - the lights lasted over 2 hours, so maybe a lighter lower capacity battery could be used.

There was an unplanned "battery ejection event" during the flight, which was quite surreal, as the kite just vanished in mid-air. Of course more work is needed on securing the battery and holder in place more securely - the current arrangement of double-sided velcro wrapped around the battery and holder and under the spine velcro doesn't grip enough.

More work is also needed on fixing the lights to the kite securely but allowing them to be easily removed - so far that's proving to be a lot trickier than it sounds.

That is, without a doubt, the best lighting scheme for a stunt kite I have ever seen..

Well done. ;)

Could you post a few pics? 

That's really a great set up and better than the cheesy light strings I was going to use.

I'll post pics when I have fixed it up again

Thank you very much.  Looking forward to seeing the set up.

It looked to me like this video was shot in the rain too?  Either that or the light coming from behind the kite was making the asphalt look shimmering against the lights on the kite.  Inquiring eyes want to know :-\

It was shot on a beach (here: http://g.co/maps/ptyqh (http://g.co/maps/ptyqh)) with a river running across it, so there is sand and water, but no ashphalt (or tarmac, as it is know on this side of the pond).

I have flown kites in the rain, but never electrified ones ;-)

Aah!  I'm at least glad I was not seeing things then....it was water!

thanks,
