HBFP is short for Honey Bee Fixed Pitch. It is made my E-Sky and the pitch of the blades are fixed, so you control altitude my the speed of the rotors. Here is a link to a good helicopter supplier that carries the HBFP and carries parts for it.

A lot of people on the Struggling with single rotor basics thread have/had that helicopter.
