Hi people, im new here from Puerto Rico, like a month I receive my fc40, now he have 2 axis gimbal, hero3 camera and vision props. I never use the IOC switch because it result "abnormal" to me, so I put it off in the assistan software but I notice that I can use the switch to put the gains control, so now I use it to control 3 range of the attitude (2) and yaw gains, I know that is not presise like a knob but now I can use the switch to have 3 diferent sensitive of my phantom. I like to know your opinion and also if you think that if is possible to put a knob where is the switch? Thanks for read and sorry about my bad English. Fernand
