Gemfan 9 x 4.7 Multicopter Prop Set (CW/CCW)

Product Rating:

Product Review (submitted on February 1, 2013):

Using these on the CF2822 1200kv motors sold on this site, and they work great (3s battery). Motor always comes down cool. I could probably go to a 10x4.7 without issue, but these provide plenty of thrust.

They are pretty flexible, which has actually been a big benefit after 2 nose first crashes. haven't broken a prop yet! Not sure how much power is sapped by the blades flexing, but they produce plenty of thrust anyways.
