Fly:Manual isn't supposed to use GPS, but I can't start the motors until the Solo gets a GPS lock. I want to launch without the use of GPS. I might not be near an open field for a launch. When near objects, I don't want to risk having the Solo move into an object because of the GPS. I have button A programmed for Fly:Manual. I press button A and verify on the controller screen that it's in Fly:Manual mode. I can't start motors (Arm) by moving the left control stick down and to the right or with the Fly button, The only way I can Arm my Solo is by first getting a GPS lock. What am I doing wrong? How can I launch in Fly:Manual without first getting a GPS lock?
