    RC Tiger U7 420 motor cables only 16 AWG

    Hello, I am currently building a rig with U7 420 KV motors. The motors come with 16 AWG cables on it. To me this seems to be a bit thin as the motors can run up to 40A. My rig draws around 12,5A per motor on hover. Any idea if 16 AWG is enough for the U7´s` Greetings

    Hello, I currently have a s800 airframe with zenmuse gimbal which I really like. It has some flex in the arms but with some upgrades it flies really well.
