The Blade® 500 3D BNF Basic is designed for intermediate-to-experienced heli pilots who want a big, powerful 3D machine they can simply bind to their DSM2®/DSMX® transmitter and fly. It comes out of the box equipped for aggressive 3D with an E-flite® 520H 1320Kv brushless motor. This awesome power is complemented by the kind of state-of-the-art electronics and engineering you would expect to find in more expensive kits that take hours to build.
