I'm new to drones but an active RC flier. I just bought a HeliMax Form 500. I was flying the F5 on it's 2nd flight of the day, 4th flight overall when it just shut down and fell from the sky into the water I had just flown over. Both batteries were fully charged so not sure why the shutdown. I was able to retrieve the F5 and it is now on it's way back to Hobby Services for a post mortum. I sent HS the video from my GoPro which continued to record until I pulled it from the water. I was flying with the Hubsan 7000mah battery supplied with the F5 as part of a deal by Tower when it went down.
Anyone else have a similar event?
