This is my 2nd crash of a Fury within a 2 month period. Both times seem to be equipment problems.

The latest happened just when the heli was flying great. Sunday afternoon during my 5th flight I noticed at one point that the heli
veered to the left (left cyclic or a faulty S9252). I quickly correctly and everything was ok. I figured it may have been me as maybe I was getting tired??

But then again yesterday during my first flight I did some quick inverted flying and then proceeded to fly across the field when something happened and the heli just did it's own thing. I hit throttle hold..and the throttle dropped down but I was unable to save it and it crashed on its landing gear. Lost the blades, tailboom, drive tube, front horizontal mount (battery weight bent it down!), muffler$$.

Of course when I checked everything out it all worked. Somehow I think vibration is getting to a servo and its losing its center??? I will have to send in all the radio gear to have it checked out.

Check your failsafe settings if PCM!

Failsafe Settings

Basically I have my failsafe settings to go to neutral on the cyclic, low throttle (idle), and the tail at neutral w/ heading hold. Pitch is set at approx. 0 degrees.

I also somewhat cooked my clutch last week and even though it is working properly there is a somewhat metallic sound at times. I also noticed when I disassembled it that the main large bearing has a spot where there is a notch or uneven spot. I hope that this isn't causing any noise or vibration?

Check your servo leads.........

Those Fury frames Eat servo leads very quickly as there is some really sharp edges.

I'd suggest removing the servos one at a time and check the wires for chaffing.

Send that clutch back to MA for an overhaul and I personally wouldn't fly it again until I got it repaired.

That heli is trying to tell you something, it's up to you to listen.

Yes, agreed

It's saying "Replace Me"

Seriously, those instances of which you spoke could contribute to the noise, however It's hard to believe you took that much of a hit to make it go to failsafe, especially where you said you were flying across the field inverted (in close proximity)

Run a simple test. On the bench, turn your transmitter on and then turn your receiver on. Wait for the gyro to settle. Engine off. Now turn off your transmitter and see what happens to the swashplate. Failsafe should kick in in a second or two. Does the swashplate go to the netural level position you expect?

I have seen a few instances of where people had thought they had programmed a neutral swash for failsafe but in fact they had not.

If the swashplate ends up lopsided, then you have your answer.

I am not saying this is definitely your problem but it's one thing to check.

Failsafe working?

Yes I have done all that many times and the swashplate goes to neutral perfectly....nice and level as in a hover.

I know how the failsafe works and how to set it up.

Have to check out all the servo wires but so far the first two are fine. Servos all work perfectly too..... Of course with some vibration all things may change.

Thanks for all your tips!
