Raptor E820-Thunder Tiger

Monster 3D Powerhouse!
Thunder Tiger didn't design the E820 for beginners; in the hands of an experienced pilot, however, it is a thing of beauty. Impressive power drives the performance of this heli, allowing pilots to go from break-neck 3D stunts to straight-line flight instantly. Steel shafts and working parts give the Raptor durability while its carbon fiber frame makes it light. When you've flown a few helis and you're ready to take your performance up a few dozen notches, build the E820 and wow the crowds with the elegant, agile and aggressive E820.
