viewtopic.php?f=19&t=8820 I am copying this post here because I stumbled on to it in the P2 forum. I have a P2V and unknowingly bought some of these blades. They made my P2V almost impossible to fly. They look very similar but are not right. I posted two weeks ago about upward lift and putting one of these blades on definitely was the cause. Now that I think about it, it makes perfect sense. That blade was not getting proper lift so she tilted hard right and the other blades tried to compensate so she started to go upward. I put my worn old DJI branded blades back on and she flew perfect. Avoid these aftermarket blades!
