I really like a lot these propellers they have great dynamic quality with a 1020 coreless with gear box reducer as with a brushless motor 1S using direct drive. For this order, for the first time, they have been wrapped with bubble wrap inside the plastic envelop :

I really like a lot these propellers they have great dynamic quality with a 1020 coreless with gear box reducer as with a brushless motor 1S using direct drive. For this order, for the first time, they have been wrapped with bubble wrap inside the plastic envelop : "Champagne!!!" like we said in my language, it means that it's an event that deserve to be celebrate! So this time I will not complain about a negligent package, but maybe it was useful to do it before to convince them to change, who knows? For information the propeller spinner is black with the shame shape as the pictures of the announce. It's nice to put five stars when you bought something little bit expansive like this item, and not in the intention that the feedback will be published for explaining that the package lacks of care. Thanks for the progress about package protection please go on like this!

Great propellers for 400mm mini warbirds. Better than the Volantex/Eachine one because of an increase pitch. Quite resistant to crashes compared with the 130/70volantex one, but not immortal : thats the reason why I make my little spare stock. When this propeller is used with a Volantex warbird you have to considerate and promote heat dissipation of the motor, because the motor could overheat; as the current is higher, the power is higher and the heat generated by the motor too. To be honest this propeller used with the Volantex gear box reduce the motor lifespan, less of course, if this one is correctly cooled by airflow. The dynamic gain is so great that now I find boring my warbirds with the stock propeller. I adapt it and I put a jst red plug for the battery because the Molex is a poor connector when it is used with current above 3 amp : it become hot and the heat generated is some lost energy for the airplane motion. They are not cheap for sure, but they are light, have high efficiency and they are pretty well balanced.
