Designed; built and flown by Graham Dorschell this big 4 x 70mm electric ducted fan powered not only looks great but sounds fantastic in the air...especially on fly bys at low power.

nice
And in case it wasn't obvious! (and it wasn't to me)...the builder put the whistles from 4 NERF balls inside the ducts to give that sound when the motors are not running. Sounded brilliant!
Very nice :thumbsup:
looks gorgeous and sounds too
