During the last three weeks, I built a depron foam 63'' R/C Lockheed C-141 Starlifter for my senior project in HS. The plane flew well!
There are four Dr. Mad Thrust 4300kv 50mm 10-blade fans powering this 141 along with a 4S 5200mah battery and 40A ESCs. Even with this large battery and light airframe, I get less than 3 minutes of flight time.
I did not take any video of the build but I documented it with plenty of pictures (plus plans and three-views) in this RCG thread: http://www.rcgroups.com/forums/showth...
