Man, what a depressing Easter :(.
My TRex450 is waiting on parts after having the tail brake loose and spinning into a tree, (same cause as from what I did with the 200 below). So I too my only other two flyable birds out.
I took my 200 out to the field and was doing some simple flips. I stopped inverted and held it for a few seconds, the nosed forward/upright again. I was a little slow on collective and is swooped down a bit, (I was doing this up around 60'), but when I gave her up collective, the tail broke loose and it spun into the ground.
Next fatality was my beloved 550. I'm still not positive what went wrong here. I was doing some simple circuits, a few flips, then came back in around 4:30 and was hovering 8' in the air getting ready for a gentle touchdown. Suddenly, it quickly went a bit sideways, and what looks like either lost cyclic, or went a bit negative.
I lost the boom, vertical fin, tail blades, carbon mains, main gear, main shaft, feathering shaft, canopy, landing gear, and one set of servo gears.
The only thing I could find wrong was one ball was out on the plastic seesaw (all metal head except this). Could losing the control arm from the see saw to the flybar have caused this, or is this more of a result of the crash?
I'm running the AR6200 receiver, and have never seen any glitches, etc.

i'd bet it's the screw that came out. i really can't believe how soft the plastic is on the seesaw. i've got the xes head, but it still had the plastic seesaw for some reason. one day, i was just checking all screws for tightness and one screw came out just tugging on the link a bit. i was suprised to say the least. if they are going to use a plastic seesaw the least they could do would be to use a hard plastic that will hold threads well.

@CompuFoil: Sorry for your loss! I had the Problem with the ball coming off the seesaw to but only after a crash. I am doing flips and fast forward 8. But never lost a ball on the seesaw in flight. i have ordered the metal one but haven't had time to install it yet.

I had 3 dirt dives so far with my hurry and every time the seesaw was busted. The screw just ripped out of the plastic. I think a longer self tapping screw would be much better. And as finnless says a drop of CA isn't a bad thing to do!

have fun reconstructing yout birds! I Hope you get into the air soon!
