Ben Hui had been planning on purchasing an RC helicopter, but with a little more reading he was determined to build his own (cache). Most of the bracketry is built out of the fiber board base used for PCBS. He has details of how he constructed the swashplate, rotor head, tail rotor, and how to make your own blades. He eventually modified a brushless CDROM motor to drive the main rotor.
