Two complete sets of 8X4.5 CF props. These are not reamed out/weakened mod'ed props but "made for phantom" (i.e. keyed) and ready to mount. One set is balanced. As a note - I suggest balancing by adding thin tape to light side and NOT buy sanding CF. CF dust is very very nasty stuff. Remember, two sets - located in Chicago and will ship CONUS for $37. Thrust/lift seems much better than plastic stock ones. One set unused, one set lightly used (like new) and balanced.
