Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month
Price: *****
Ease of Use: *****
Build Quality: **
Usefulness: **
Overall Rating: ***
Pros:More rigid than the plastic propellers
Cons:The hubs are VERY imbalanced...I would not spend my money on this brand anymore...I also have a 1045 gemfan with same heavily off-balanced hub.
Also the adaptors will not fir the Sunnysky X2212 980 kv motors without modificarions
Other Thoughts:I loaded a lot of hotglue on the hub to balance which is not something advisable on a decent prop...
Bottomline:Balancing these is not easy, and to be honest for 5 usd more you can find more "balanced" props out of the box.
