Was not very impressed with these. All 4 I received were very out of balance and required a lot of work to get balanced. Where as the Gemfan Propeller 6x4.5 (CW/CCW) (2pcs)PRODUCT ID: 329000334-0 I also purchased were perfect and performed better on the test bench and in flight.Holly wow!
Precision and balanced very well. The build and strength is amazing. The perfect fit. These are some really nice props. I am very impressed with every aspect of them. The shipping like always was a little bit of waiting, but more than worth it. They seem quiet compared to other plastic props, or maybe that's just me.
Thank you Quanum!, and Thank you Hobbyking!!good quality prop and affordable price.
