if the heli you have has only two blades per rotor, is only 2 channel, and has a cage around the rotors, its probably the Spin Blade helicopter. the BladeRunner has 4 blades per rotor, is 3 channels, and has no cage. both the spinblade and BR are meant for indoor use only, especially the BR (even a very light gust can crash it). both are cool helis, and both can be modded endlessly.

here's a thread on the BladeRunner: http://www.rcuniverse.com/forum/m_2601563/tm.htm

i attatched a pic of the SpinBlade heli. if it is the spinblade, dont get rid of it, i think they may have stopped production on them already.
