so sometimes if I land and still have motors idling, sometimes... they will gradually get back up to speed and if left long enough take off... I need to either shut off motors or hold down throttle a little to keep it from revving back up. When it happens its a slow gradual increase but yeah, they do eventully go fast enough to take off. As I said, doesn't happen all the time... can't figure out under what conditions it happens... Not to much of a problem as I never leave it unattended or take my eyes off it when its on the ground and motors are running. Running newest firmware, its 3-4 weeks old.. Always done this since I have had it.. well the times it does actually do it. Any one have the same issue ??
