Ok, I have the metal arms coming. I don't want to take chances. Also, it hasn't broke 40F here in almost 5 months.

thats nothing compared to what it would have been if it was a wide frame design. My 700E had a crash that was not half that bad and the frames were toast. 150 bucks for 2 frames on the 700E. along with a ton of parts that broke due to the frames breaking, I actually had to rekit. it was bad... Most guys with a 700 will tell you, if you go in remotely hard the frames will be gone. along with a bunch of stuff that the frames are suppose to be protecting on the inside.

I am not looking forward to the first crash with my X7, but man, it cant be as bad as my 700E that's for sure.

This thing is built as solid as anything I have ever seen.

Sorry Rob. But you have to admit.. with the way you fly... you are going to crash and crash hard! Totally worth it IMO (considering how much fun you have flying). Can't wait to see it again.

Actually when you do the math, assuming that it is a $2000 machine, that is what my total would be for basic stuff, then the cost of that crash isn't bad at all .When my buddy planted his 450 Pro it was $150 crash. Considering that the bird is only $500, that is 30% the cost of the bird, vs this crash which is roughly 18% depending on the blades. Now that is assuming you would be getting the same parts I would be considering had I crashed.

Wow, you bent the feathering shaft? That thing is huge, but then again, you did sheer of the main shaft.

Some of those parts you can probably get cheaper. If you have the ends for the boom supports you should be able to just get some CF rod. Same with the torque tube, if the bearings are ok, couldn't you use an arrow shaft?

The big thing is the canopy. That is a pretty spendy part, the rest of it looked plenty reasonable to me.

Good to know! Considering this thing went in over 100mph and sheared the main shaft, and being there watching it explode into pieces over a 250x250 foot area...I know it hit HARD. All things considered, except the crown gear and TT gear, nothing within the main core was disturbed. The top main bearing is rough, but considering what it would take to break a main shaft, I'm not surprised.

Also the TT support bearing needs replacement, again, the easy/cheap stuff.

The entire tail end is perfect, except for the bent tail hub and one broken plastic pitch arm. the tail unit, both TT gears, tail shaft, all bearings, it's like brand new!

Nah, all said and done, it's a lot easier to just buy the replacement parts. TT comes with all new bearings, ends. No way I'll be cutting corners on a $2500 heli that could kill me or someone else.

I am worried though... one of the main grips had a loose arm after the crash. This would probably mean the M4 screw was pulled out and stripped the treads in the grip itself. Silly system, now I may need a whole new set of grips at $65. Why is there only 1 screw holding that entire arm into the grip? lol.

How else can I tell I wonder...If I try to tighten it, at what point is tight enough and I can trust the threads are ok? Or, at what point is too tight and thus stripping 'good' threads? ARGH.

A conundrum!

Do a permanent fix of some kind? Epoxy? Red loctite?

Maybe JB weld? Now that's permanent.

I had red on it already. Red all over this machine.

Or.. drill out and tap for M5? I don't have a tap set tho. lol!

yeah.. the black JB weld! In the entire threading.. thats not going to come apart. Then again you need with weigh the odds... hmmm "$65" vs a possible "$400". I'd try it though.

Here is what I would do:

Take the arm off the grip. Run the M4 bolt through the grip without the arm to see if it will EASILY pass through all of the threads. If you have any damaged threads, the screw will require a bit of effort to bottom out. If the screw bottoms out without any issue, loctite and go about your day. If you encounter any resistance or it won't bottom out, get a new grip.

If you know anyone with a M4 tap, that would be the best way, run a tap through gently to make sure threads are clean.
