Is the problem with the power cable length only on the DC side, the motor side, or both?
Am I reading that wing area right? 48dm² (744in²) seems very small, if root chord is (at a guess) 30cm (11.8"), tip chord is 20cm (7.8") and span is 300cm (118") then the area should be at least 75dm² (1162in²)...
Surprised no one has made a shadow model yet. I hate that flying diesel lawn mower.
@b nevins; Right about the power leads, and as we all know, long power cables lead to ESC feedback and failure!
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.
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!
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.
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.
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.
@Euan:
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.
