Aftermarket rotors or stock rotors? Which last longer? That question has now been answered in a comparative study. White aftermarket rotors do actually last longer. I ran a carefully controlled study of both rotors and timed flight time. Timer was started at the third rotor spinup at launch, and times recorded were at the "Land Soon" announcement, "Returning" attempt (which was cancelled) and "Landing in Place" announcement. Stock rotors gave me an average of 14m59s before forcing a landing, and white rotors gave me an average of 15m48s, a difference of 49 seconds, or about 5% longer flight time. Aftermarket rotors are lighter (56.5g per set vs. 63g per set.) Here's a snapshot of the data: Enjoy.View media item 20
