1s Rotors
There are some around that people have been testing, but I am not aware of any that have been shipped with motors and I am not aware of any availabe for sale at this point. Now a large motor supplier that purchases 100s of motors at a time may have the ability to take the stock rotors and check them and determine that some are weaker than others and use those for 1s application. That is very possible. It is even possible that they have some 1s rotors to play and test. However, they are not being sold via epic to the masses yet. Once they are comfortable with the performance of them, they will be released.
I hope this helps.
I am only a team guy as well and do not have full knowledge of all the workings inside and out of Epic. I am only offering what I know at this point to try and help.
Best luck to all!
