Well, I did it. Apparently I neglected to use loctite, OR neglected to tighten flybar carrier screws on my new SDX.
6th flight on it and it went into a nose dive. I was up high and had plenty of time to think about it (and watch it plumet). Killed the engine since I had zero cyclic control. About 10 feet above ground gave it all the positive pitch I had trying to save it a bit. It did save the Edge blades.
Upon post crash inspection, the flybar just flopped around with no grub screws even left to hold it even remotely tight.
I honestly cannot believe I did that as I still swear I both loctited and tightened both of the screws. Obviously I did not.
Took out main frames, grips, landing gear, tailboom, 1 mixing arm and assorted links. Havent checked the main shaft of spindle, but I am sure they are goners too.

That hurts

I recently completed a Trex 700E build and I literally went over the machine 3 times touching EVERY nut and bolt just to make sure I forgot nothing!! 61 flights on it and the only loose item I found was a landing skid screw!!

Build her back and MAKE SURE you loctite everything (as I know you will)!!

Sorry about the crash. Thanks for posting this though. It is a good lesson for all of us.

Costly mistake for sure. Not just the cost of a rebuild, I noticed I had a hard time trusting myself after the crash. I rebuilt to the tune of 100 bucks, could have been worse for sure.
One thing I did notice is how easily the landing gear broke. The frame breakage appeared to be be due to the landing gear breaking. I was planning on getting a bottom frame brace, but instead used the mavrikk super gear off my old Evo. I have had several crashes much worse than this and the Mavrikk gear held up and the frame survived. Obviously I hope I don't get a chance to test it out the durability again.

I noticed my G20 screws were really short only a couple of threads going thru the flybar control arm into the head so I replaced them with longer ones from Ace. I was just spinning it by the flybar with my finger on the bench and it let go I can't imagine the flight result being any better that yours.

So much for the theory of the Mavrikk landing gear protecting the frame. (although not sure much would have).
Had a ds610 servo fail in flight. Nothing I could do really. Failed full forward. Watched as it went in. Broke another set of frames... the Mavrikk "Indestructable landing gear", Edge blades. Main and feathering shaft bent, tail boom and killed the Lipo rx pack. On top of this, I am needing 3 new servos since I will no longer trust Align servos. These were new servos with less than 10 flights on them. Should have gone with Futaba. Lesson learned.
On the plus side, I have 2 DS610 servos for sale.

Oh yeah, and to add insult to injury, I had finally got it dialed in exactly where I liked it....

I never use Locktite and I have had only seven crashes from parts falling off in flight.

Hmm...

Where do you get this Locktite stuff?

Maybe you'll have better luck on your eighth flight
