so today I finally had a minor crash with my spark. Caught a tree branch, broke a rotor and the spark got hung up on the tree limb. After a little work managed to get the spark down from from the tree from a height of 10ft with the only the damage To the rotor rear rotor blade. So after 40 flights just when I thought I had a good grasp on flying I relied on the RC controller view to much and thought I was farther from the edge of the trees then I actually was, lost sight for a few seconds and it happened. Lesson learned keep your line of sight and don’t rely on the screen as much while flying. Good news the spark is one tough little machine with only the rotor blade damage. Replaced the rotor blade ran a test and was back up and flying in about 15min.
