Yesterday out flying with the Sceadu, and a few minutes into it, the TR boom mount broke. I am using a purple DBC mount from Heliproz, and have had it for a few months, no problems at all. It was the plate that the servo mounts to, and it broke in half thru the upper servo mount holes. Broke clean thru. I was able to save the heli that time, but in my eagerness to get back in the air, I repaired the plate with a few backup plates I made and bolted it all back together. 5 min into the next flight, just hovering around, it broke again, same exact spot. This time it took out everything on the heli, except the electronics and engine. I called HP and they said that they have never heard of that happening. They offered to replace it right away, but since the heli is down for more parts, I declined, but much appreciated the offer. Anyway, the heli is completely smooth, no vibes at all, at any speed. Has anyone found anything similar, and what did it break? I am going back to the stock TR setup from now on, just to be safe. The heli wasn't crashed with that new mount b4 it broke, so I know it wasn't prior damage, it is obviously vibration fatigue, but there is none visible. Any ideas out there?
