Yes,they are compatible with NAZA V2. Only the EMAX brand ESC are not compatible with NAZA. You must calibrate the ESC first before using. Any further problems you can email us we will sove for you.

Yes you can remove the red line,it is bec 5v supply.

Q: Can these handle a 11.1v lipo?

They should be able to handle it. Even up to 16v.

Q: How do i a access the menu?

If you look in the product description it states "★★★Note: This ESC is not able to flash the firmware." so I'm guessing that's what you mean, if so, there is no menu. They are what they are, no programming ability
