Old news guys. The Eflite Tandem Rescue was discontinued last month. Picked-up two of them (new) off ebay for $114.89 including shipping. The mCX-S300 was discontinued in August 2010. Finding these are a little more trouble. I found one on ebay (RTF) for $76.00 including S/H & I was lucky as hell to get it @ that price! Usually BNF versions go for $80.00+ these days.
