I am sure I am not the first one facing the dilemma – plastic vs. carbon – when choosing multicopter props. Carbon fiber is twice as expensive. On the other hand, props are the key moving part and may significantly affect your rig’s performance, battery life, and most of all video quality. To put the issue to rest once and for all I did my own test using an iPhone vibrometer app and two sets of 10x45 plastic and carbon fiber props, 12 vs 8 grams a piece respectively.
Both sets (hexacopter) have never been balanced before and ran at the same minimum throttle speed. Plastic props vibrated at 1.6-1.8 m/s2. They also produced more noise.
Carbon fiber props ran at healthy 0.2 - 0.3 m/s2 and sounded much better. Also, they are significantly lighter and stronger than plastic.
Cautionary note – carbon fiber props are very stiff and sharp. Carbon fiber is 100 times stronger than aluminum and can cause bodily harm at high speeds. You should handle them with extra care.
