A few days ago I destroyed the frame that I have been flying for the past two weeks. I made a nice pile of broken parts:
Two dt700s in the front and a dt900 in the back. It flew for 15 minutes or so. The booms are made from ~4'x1.5"x0.5" balsa. After flying it once I have decided to rebuild it into a much smaller and lighter form. I'm going to work on it tonight and hopefully will have a smaller version built by tomorrow. The huge tricopter was a little too intimidating. The balsa arms were far too fragile also and they broke twice before I even got it off of the ground. I will try a version with stubby plywood arms this time.
