The biggest model airplane I have seen was during the recently held F3A world 
champs in Kasaoka, Japan, where they during the airshow day flew a huge 
Boeing 747. It was powered by 2 (!) turbine jets (Sanwa Electronics). The 
remaining 2 engines were just mockups which I understood when the Japanese 
crew told me that the price of those jet engines was about $6,000.00 each.
After lots of preparatory work and repeat failed engine starts, finally they 
got the two jets working, revving at 100,000 rpm.
The two engines, sounding just right, produced more than enough power for the 
huge 747 to take off. Actually it built up too much speed, and in order to 
hold the airplane within the flying area the pilot made a too steep 90 degree 
banked turn. The tailplane was overloaded and was instantly ripped off. Then 
we were all whitnesses to one of the most expensive model airplane crashes 
ever...
