If the build quality and spar strength is anything like their 2.5m reaper then it's rubbish. Would be good to see it flying fully loaded first.

Just a heads up. The "Reaper" wannabe models in general look good, but is a terrible R/C design. The wing shape/placement is primarily done for full scale efficiency. It does not scale down very well, and the result is some brutal stall characteristics.

Holy ****!

I have a funny feeling that slapping 2 x 11,000mAh 6S in here will serious affect CoG (it looks like everything goes in the front, and a good way forward of the CoL), but would give huge flight times if you can make it work.

Agreed with John - unless there's something I'm not seeing here, these wings will fluttering like a butterfly if you load this up and there's not enough internal sparring. Can't comment on the stall characteristics.

Not sure the familiarity with military drones is a good thing either - was the military grey strictly necessary?

Having said that...I secretly want one...:-)

There's a payload bay above the wing roots - especially for heavy stuff like batteries :). Check the product description :).

And about the color... It's fiberglass... Go buy a couple of spraycans in pink if you please :D.

I liked how he tried to dance around, but touch slight base on the military aspect of it, but he didn't want to drive it home to hard. I like it. But as others have mentioned, I too am wondering about the flight characteristics.

Here is the link to buy it: http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=...

$283.29 it is not a bad deal.

It will require some long power leads to balance with the motor that far back.  Hopefully this version doesn't have the wing flapping issue that makes the 74" version look like a pterodactyl.

Its funny how so many people new to the community say they want a Predator model.  

I suppose its the romantic poster child of the drone world.

No-one thinks about the fact that with the narrow wing chord and relatively short body and short tail, its a stall waiting to happen!

If you get this beauty off the ground, odds are it 'aint coming down in one piece!

Well, I guess we'll find out.  I know somebody on the Arduplane team has ordered one.  I for one really hope it works out.  Maybe this one will fly better because it's bigger?

For myself, even if it flew really well, I wonder if it's just too big to be practical?  Depending on the stall speed, I'm not sure I could even use it at my club field.  And forget catapult launches and parachute recoveries.  I also wonder if due to the size of the thing, maybe it would be better off with a fuel powered engine?  It just seems so big for electric. 

I'd also hate to have this thing crash in a populated area.  A Skywalker or X8 is one thing, but this could really do some damage.
