Review on Drone Motor Arm For SJRC F11 by John Lewis

This one didn't have an antenna because I bought the wrong one and then it can't be returned because I started taking it apart to find out. I see that there is no way for me to extend the antenna without disassembling it and it is not designed to be disassembled down the duct. But I bought the right arm for the other side and since they were pretty much the same with and without the antenna I'm giving it five stars.
