Tony Nijhuis has just sent in some pics having completed his B-50 (featured here earlier this year). With a span of just under 19 ft and weighing over 80lbs, it's one of the largest electric models you'll find anywhere. 
 
Motor power is provided courtesy of four 4-Max PPPO-6367-230 outrunner motors, each capable of developing 3kW of power and total motive power of 12kW. Battery power is provide by NiMH cells (96 in total) and be could be increased to 144..(36 cells per motor) if required. She's a beauty!
