Took my Fury Ex out over the weekend - was hovering at 5 feet and checking her out before flying out when suddenly I got an uncontrolled slow pirouette - hit throttle hold and landed. Thought my 9251 was toast.

Started going over the heli tonight and realized that all linkages were fine except the pitch slider on the tailshaft. Grease from the gear box had oozed out and had gotten in between the slider and the tailshaft making the two stick together and very difficult to slide over each other. Cleaned it out and now the tail works like a charm.

Just goes to show that just when you think you have thought of everything, something else sneaks up on you.

What type of grease was in your tail box ?
That would also make for sluggish tail / gyro response and a lot of work
for the tail servo.
I've been using the ma grease without any probs, I lube the area
often with tri-flow and it stays really clean / smooth.

I think you are right - I have to take the box apart and inspect.

I am using Tri-flow grease!

I am using Tri-flow grease!
I have some of that grease and have used it for thrust bearings in the head and also in a plastic geared tail case before with no probs.
I was going to try it in my MA tail box and while at freestyle3d asked
the man TB , he advised not to since he has heard of problems with
it in MA tail boxes stripping gears.
So I've stuck with using the MA syn grease and have had really good luck so far, I add some occasionally, the tri-flow I use on the tail slider
is the liquid drip type.
