What a day. Went out flying at my place, flew for 15 minutes all going good. Came back for a landing all of a sudden it started to shudder while hovering. Tried to bring it down, no joy. I read on a site to push the red button. Did it. Started to come down. Got ready to push it again and she started to drop from about 6 feet. Hit the ground broke a landing gear actuator and one rotor. The H took off again. I grabbed it mid flight. Held the red button and killed the rotors. As Im walking back pondering my next step I catch a whif of hot electronics. One rotor is so hot you can't touch it. Maybe the reason for the shudder, I don' know. Now to decide if I jist send it in or do repairs myself.
