DJI have just announced their own E300 carbon props for the Phantom series:
"The 9443 CFR rotor uses innovative carbon fiber reinforced composites in its manufacturing, instead of the additional glass fiber reinforced plastic. This advanced material combined with an ultra-thin profile guarantees extremely high levels of rigidity along with low amounts of inertia, to be more dynamic thrust. "
