There seems to be some confusion. The plane shown, and the plane we have, is the Mugin, probably as supplied by a Chinese manufacturer when purchased from FPV-flying or FPV-Hobby.
It was presented to us by Cyber Technology after making quite a few modifications including the full installation of servos, change of motor, and installation of a generator. The quality is - well, commensurate with the price. Looks good out of the box, suffers from hangar rash very quickly, and in my opinion it is great to play with, but just not quite good enough to fit out and on sell for a commercial application.
The similarity with the Shadow appears to be in format only. The Shadow seems to be a fully commercial aircraft from quite a different stable.
Not That I have any real dreams of going comercial, I just like to push myself. I would design a manned UAV the size of a private jet and fly myself to different destinations with my Logitech controller if I could. LOL But until then I will try to buy cool looking cheap planes and try to make them pretend to be commercial grade for my own fun. I was just confused by the number of names I have seen this plane listed as. But let my try tounderstand...The plane is from fpvhobby, and upgraded by Cyber tech? If that is correct how much was the generator upgrade and hangar rash how? Thanks for your patience. I become more of a noob every day.
The internals of the fuselage are 930 x 190 deep, 210 wide. A 21 x 24 longeron projects into this space at each corner. The rear bay is 320 long with the wing spar tubes projecting 44 down into the space.
The middle bay is 320 long with a radio box projecting 85 down onto it.
Assuming the 6" and 7" sides make up the two sides of the right triangle, your tank will not quite fit under the wing spar tubes at the centre of gravity.
In the picture above you can see 4.5 Kg of battery at the front - this was installed just to balance the plane with minimal equipment.
