Quad copter flying for 4-8 hours

Posted by lot on August 28, 2012 at 5:09pm

Hi all,

I just want to know your opinion about this page:
http://uniteddrones.com/products/aether-aero/

It says that their quadcopter can fly for 4-8 hours thanks to their propietary technology.

Anyone knows something about this? It it's possible?

flying, perfomance, quadcopter, time

Thank you kindly.

I think this post requires an update. Joel.Lovell deserves an answer, and that answer is yes, over 2 hr flight time, with expectations to double that.

I would like to see drones using fuel cell technology. Anyone have any good information on that? Take a look at this companies power cell technology:

Lithium batteries have the most density of comercial batteries today.

I think it's possible. Just compare your flight 2500 mAh battery and AA rechargeables with the same capacity. About 10 times smaller and lighter, yes?

So, we just need more discharge rate from these AA's - to put them in parallel. As much as possible. And than we get 10 times more power, I think.

85 knots ? bahahahahahahahhahahahhahahahhahahahahahahahhahahahahahahahahhahaha

johnny I have seen an indoor flight of over 90 mins, but thats indoor,

I saw some hydrogen /lipo fusion fuel cells the other day that are being used in UAV´s if they use that then they might be able to acheive it, but the fuel cells themselves weigh several kilos, i doubt a cuad that small can carry them and still be stable

I think 4-8hrs should be possible in future, there are some very exciting battery technology in development.
Lithium-Sulphur battery have double the energy per weight of the current LIPOs. Given that the current record of flight time is around one hour. It might easily give flight time of 2 hours.

And Lithium-Air battery has 9 times the energy density.... 8hrs flight time should not be too difficult.

Unless you’re operating on another planet that has one twentieth the gravity of earth and an atmospheric density at least 5 times greater than earth, you cannot change the laws of physics if you plan on using lipo batteries. This is one of those posts that are fantasy. Do the math :-)
