110.31CFM = 187,3 m³/h = 3129 liter per minute !!!!
this is [B]5 times[/B] the airflow that my [URL="http://www.youtube.com/watch?v=eG4Hf6WNpTc"]coleman quickpump[/URL] produces !!!
i will combine this with a battery holder:

a tube and a switch. i hope my new prefiller will fill my 16 m scorpion and my brand new 13 meter scorp (arrived today!!) in 20 to 60 seconds.
i will make a video as soon as i have to components together.
What you may want to do is just go to Home Depot or Lowes, find yourself a battery powered leaf blower. Those can be purchased for about 40-70 bucks
depending on sales. It comes with a charger, battery and blower motor. This will fill the kite in about a minute.
Another option for the fan is to go to a marine store and get an engine exhaust fan. Those come in a longer tubed unit and hoses that will fit inside
the kite very easily. You can mount your batteries right on the base of the fan-tube.
all sorts of leaf blowers and also my coleman quickpump are quite heavy. my selfmade blower from a pc chassis fan will weight much less. and it will
be much more silent.
i dont know about "engine exhaust fans", will google about that. thanks for the tip!
You have it right Herc. What you have there will work like a charm. Radio Shack has a rechargeable battery I think 17v meant for RC cars. Comes
with a charger for $17. That muffin fan filled my 18m Phantom in 4 min or so; about the time it takes to lay our your lines and bar. And so light
you forget you have it.
Ah, just saw you are in Germany, so if no Radio shack you can figure something out.

Depending on your flying location, I would expect that firing up a gas powered leaf blower would have some folks seriously reconsidering installing
that center console mount for their H&K MP5 :o

I've always wanted a P90
Been looking for a battery powered leaf blower, hopefully I can just slot my B&D battery pack into but they just don't exist here - guess you have
to have a garden to have trees that drop leaves and not have a slave sorry wife who's got nothing better to do than sweep all day and figure out new
and creative ways to piss off the neighbors ...!
So in other words, I might have to DIY a blower too ... actually, I think I have that exact fan sitting on top of a heatsink I can't use ...
At a guess, 5.5 amp 12 volt marine battery.... about the size of a motorcycle battery... maybe a tad smaller.
If you make a plywood battery stand (something along the lines of a r/c field box), you could mount the exhaust vent blower on top. Removable side
panel to easy removal of battery and charging tasks.
A length of flexible 4" hose to aid in routing air into the kites inflation panel and you're good to go.
Just thinking out loud....
ATB,
Sam

Still too much to cart around :D or leave lying on the beach for nosey children to bugger.
I wonder how many CFM those little <80mm PC fans pump ... could tuck something like that in a backpack ...
50x50x10mm = 9 CFM ... do you get multiples of performance if you stack them? eg. 3 fans inline = 3 x 9 = 27 CFM?
@kami: coool fan matrix :-) must have been a bit noisy, though..
nonetheless i would buy that slipstream fan with its 110 cfm, instewad of stacking 80 mm fans with low air throughput.
the lighter, the better. and the slipstream only weights 115 gramm..
yeah, low winds (wind gradient leaves little wind on the ground, but enough above) and/ or older ARCs with the single inflate zipper in the middle
instead of one at each end.

I don't usually fly if theres not enough wind on the ground to prefill. I'm really big into jumping with ATB and if there isn't enough to prefill,
then there usually isn't enough for big air. Although there are those occasional days when I havn't flown in a few weeks and I simply want to have a
kite in the air above me so I can get a quick fix.
really low wind, i can see inland light air and to save some time. but my experience is fill in 1-2min, set lines for launch, then 15 sec top- off
-fill, then GO! scorps need a little extra in most cases, and that seems to be the case for some .
never even considered it. kinda goes against the nature of the no pump mantra, IMHO .
but(just recently) i do love to dry them at the house with the leaf blower, kinda neat.
not until guys on hear where talking about it. helps with repairs, drying and cleaning if the wind is down and my idle hands need help
If there isn't enough wind to inflate the kite, then there usually isn't enough wind to board with - but if you can fill the kite then you can usually
fly it. We use the fan to blow the kite up at the park in the ultra light wind for lessons and teaching people how to use the depower system and
control bars.
For the batteries on the fan, we use two of the RC NiMh batteries on the bottom to provide the juice. It will last about 10 minutes continuous enough
for about 5-6 inflates on the arc's.
The whole thing with batteries and 2 ft. of 4" vent fits easily in the backpack with the kite & gear. Weighs appx. 3-4 pounds. You can recharge
the RC batteries off your car if needed.
Yeah what Kent said is pops back into my mind everytime I start thinking about building one of these
... and do I REALLY want to admit that I need a pump for my arc? :evil:

That was very informative, or at least somewhat. And my three year old grandaughter found it funny when it hit the tree and then each consecutive time
it did it.

I bit the bullet and bought a Coleman battery operated pump for air beds and stuff. It was only $19.99 and looks the job. I'll post up a report on how
it works 1st chance I get to use it.
You can also get a cheap cordless / rechargable leaf blower for 30-50$. That would preinflate the kite pretty dang fast. I' have one, haven't used
it for pre-inflation, but it pumps out a good bit of air and lasts about 60m on a charge.

No cordless leaf blowers in any store I've been to - and I've been to ALL the DIY/hardware stores in a 50km radius. But then, this is Japan - where
are you going to blow the leaves to except some place that'll piss the neighbors off ... better to vacuum your garden :O
