I’m a newbie and embarrassed to ask this question. I have a landing pad on order, but couldn’t wait to get my Evo off on her maiden launch. I set it up on a nearby lawn, turned on the motors, and tried to take off. First thing I noticed was the motors shut off probably due to the grass hitting the propellers. This happened several times. I tried pulling up the grass around the props. Mind you, this lawn was just cut, but was about 2” long. When I was able to initiate a takeoff, the rear props “dug” into the ground and the drone flipped over and stopped. I’m glad no one saw this or heard me shout F&#@! at top volume. This happened a couple of times, And, it took off a few times too. Am I doing something wrong, or is the Evo that finicky about the grass length when trying to initiate a takeoff?
