Upgrade your Durafly Rare Bear Reno Racer to fly on a 6S battery pack by using this dedicated Durafly 6x4.5 propeller. The Durafly Rare Bear is fast on a 4S pack, but just wait until you try a 6S, it is mind-blowingly fast and will add something like an amazing 15mph to the top speed.

However, with more speed and power comes even more responsibility on the pilot. Extra consideration must be made when balancing the prop and spinner, checking the tightness of the prop nut, inspecting the overall integrity and security of the model and control surfaces, etc.

“Please note that all testing on a 6S was performed with this Durafly RB 6x4.5 prop. This is the only prop we can recommend when using 6S. Use of other similar sizes and brands can therefore not be recommended.”
