VTOL: Chimera & Volcano blower fan-duct

When you want ducts for the Volcano or the Chimera there are plentyfull, but when you want a duct for BOTH, no luck.
Also, lets be honest, the "regular fans" or "axial fans" arent very powerfull and volcanos run fast and hot. Thus, blowerfans. More POWAH! I highly recommend em to anyone. Soooo much better.

VTOL stands for "vertacal take-off and landing" used in aircraft cabable of taking off without a runway such as the Harrier fighter-plane or just plain helicopters.
