ArcaBoard, the future?

Hi Flitetesters


I found an article about this hover board and it made me wondering.

I know some motor and battery stuff so I calculated if I would theoretically work.





On the site www.gizmag.com they say the ARCA used 36 5,5kw EDF’s to give the thrust.


A similar motor is the C580L 870kv 5kW from Turnigy. One motor uses 93A on 44V to give 6kg of thrust.

36 of these motors would need 72 4500mAh 90C lipo battery's for power.

 

Dividing 9A (from two battery’s in parallel) by 93A and we have around 0,1 as answer. 60min multiplying with 0,1 and we have 6 minutes of “flight time”.

The motors would give approximately 200kg of thrust (36x6kg). This is enough to lift the heavy board and a person.

 

 

 

So theoretically it could fly, but I still have my doubts.

(I don’t trust it about the fact that it will be released in April. Maybe 1 April J)

Although this board is wildly unpractical, very heavy and very expensive. I love the concept.

What do you think?

Let us know.

I have seen a couple of ideas like this but the problem is always flight time. I would love to build one but it would be so expensive.

Interesting idea; thanks for letting us know and for explaining how it works.

I wonder what would happen if one of those batteries caught on fire... ;)

Already having trouble with personal FPV drones, now they're thinking about a personal lifting-capable hoverboard ?! Something doesn't sound right...
What's more, 20 000 $ for a 6-minute flight time and a 9-hour recharge is a bit overkilled...
I wonder how much it would cost to Flite Test to make a similar machine from HK electronics... :-P

I bet it sounds like the world's loudest vacuum cleaner.

And if you're after a hover-board, wouldn't it be best to use some sort of ground effect so if someone falls off if it, it would be impossible for the board to shoot up. Similar to a Ground Effect Vehicle, but using upward thrust instead of forward thrust, somehow.

^^ditto to the noise comment above. Notice that they never showed what it sounded like.

In addition, it looks pretty hard to control. They all seem to be just balanced enough to keep themselves from falling off. In addition, there is no footage of them really going anywhere on it.

oh yes but all great inventions started with "What If?" just proof it can work, sets talented and genius people to solving why it doesn't work well....
