Quick review: Gemfan 5x3 (5030) 3 leaf propellers
This will be very quick review with a simple conclusion: I will never buy Gemfan 5030 3 leaf propellers again. Never. Why? They are cheap, you can buy them for around $3 for 2 pairs from China. But they have few flaws:
- Every crash, even gentle means at least one broken propeller,
- Quality is low,
- Look at this picture: This propeller never hit anything in its life. See white stress marks near hub? They appeared during normal flight. This prop would break soon,
- At least twice in last 2 months Gemfan 5030 3 leaf broke in flight. In both cases during quite normal flight. No crazy stuff. Simple turn.
So, my verdict is: no, never again. I'm going back to Gemfan 5030 2 leaf version. They are cheaper and offer very similar performance. And I think they are slightly harder to break after all.
