Larger (520mm mainblades) scale electric

[RAV50]

Check out this rather larger scale electric - I saw some video of it in flight - very impressive, specially with the functional retracts.

Not only does that look scale but I bet it sounds sclae in flight also - turbine sound with no smoke trail.:thumbup:
