I am not sure what the actual title of these parts are, but i need replacements for the aluminum conical parts that hold the propeller onto the axle of the motor. I have the previous version of Arducopter (4 arm).
I am not sure where to find this part--can someone tell me the name, and any sizing information so I can find this part either on diydrones store or a hardware/hobby store?
If you have the purple 880kv motors, you can get them for $1 shipped at rctimer.com, but they will take a month to show up.
Look for the 3.17mm prop adaptors
I am using this Eflite part on the 850V motors (looks like it is the same size shaft as the 880kV)
