I just wonder why it has 2 bladed props though...

hard to tell, but that B52 may have been larger - before it crashed ...
It's probably got two blade props as it may not have enough power to turn four bladed prop's of that diamter.

BTH, I'd love to see a similar scale "Spruce Goose", esp' as it's a seaplane.

lies its nowhere near the size of a predator unmanned aircraft which is pretty much an RC plane :P
27 feet (8.22 meters)
Wingspan: 48.7 feet (14.8 meters)
Height: 6.9 feet (2.1 meters)

I hate the engine sound. Sounds horrible. Nice plane though. Reminds me of an old Byron B-29.

They use little two-bladed propellers because noisy little piston engines don't have enough torque to spin large four bladed props. They have RPM instead so they spin small two-bladed props.

I think the Spruce Goose model fo the movie "The Aviator" is the largest RC model (not UAV), but I'm not 100% sure.
