Main units are HobbyKing 10 blade alloy 70mm EDF unit 4s 3000kv 1200watt, rear unit is Dr. Mad Thrust 50mm 10 Blade Alloy EDF 3300kv. HobbyKing have a vast range of these. Being alloy construction, they don't distort under load like the plastic ones.
Build so far is around 600 hours over an 18 month period, so, sorry guys, I have to resist the temptation to rush into the first flight. I'm fitting a temporary u/c now for the first hops, on long grass!
James, think hard before converting to ducted fans. I had no choice with this one, for realism, but they really suck the power. Hovering current is 100A from 5.6Ah 4S cells, giving around 3 minutes flight time. But the noise is so cool, a sort of whine scream whoosh! Especially from the HobbyKing multiblade units I'm using.
Not very afraid of Skynet when it's hanging by a rope-swing from a tree, I wonder if this is how an advanced machine intelligence would test robots? Looks pretty cool though.

Hi Treville,

That is so awesome! What kind of motors did you use/where did you find them?

Looks like it's doing fine. Time to cut it loose and fly it! I'd like to see it when you do.
Yes, I'm fully expecting it to become self-aware at some point. Probably just after I fit machine guns and rockets.
So this is how the end begins.
The result is very convincing. From the looks i would have sworn that it was molded plastic. I cant wait to see it fly :)
Now that is a FANTASTIC justification for using ducted fans on a copter :)
Well done!
