1 - Yes, you can use all CW threads on your Quadcopter. The ideal of CCW & CW threads is to match the rotation of your motor and have less chance of a prop getting off the motor. This mostly happen when you hit the ground or if you didn’t tight it properly. I’ve been running CW only threads on all my multirotor.
2 - The hub itself (alone) is not available through RobotShop as it was a very low seller and we had to keep stock of them. Our system just discontinued them at one point.
I recently broke my drone and took it for repair.
I am offered to replace Prop Shafts with the same as yours.
And, on the Brushless Rotor Motor 1000Kv 15A - RobotShop.
Please tell me how is it to you?
Should I buy it or look for a replacement?
