yah there was an updated hub that came out with the titan SE. also the newer bearings that are important to have installed in the correct direction. only the X50's (newer TT helis) have thrust bearings in the tail.TT X50 Nitro

Joel, let me know if you need a tail assembly, I've got a lot of them on the shelf built for after I crash I can get back up quickly.

If your 90 is 2008 or newer, it may also have been upgraded. If the tail bearings has black and red shields on them, make sure the orientation is right.

Great thread. Will be good for future reference.
Did some screw box cleanup to get rid of odds and ends, it's a brain
destroyer.

Ok, glad I waited till now to re-assemble.

that warning is awsome lol im assuming that what they are saying is, if installed in the wrong direction, the bearings will seize up and throw your heli into an uncontrollable piro and lead to a crash? sounds about right eh?TT X50 Nitro

Red and black bearing retainer grease barrier.
Thanks, Heli 770 for the bearing information.
Would have never checked those. They were in the right way.
The gear could use the shim, but the play on the gear is not bad
as it is.

Did find a missing locknut, that was replaced with a regular nut with no threadlock.Again, I have been checking and re-checking, and it's another miss.
Makes you appreciate what it takes, on a full scale"real" helicopter,
to keep up with.

Neither the older R50s or R90s had thrust bearings.
You're right! I had forgotten. My R60 has radial bearings in the tail as well.

The tail is clean, rebuilt, checked light
lithium on gears,light lithium on shaft(note to self:should take the stuff myself),weighed tail feathers, longitudinally, shaft free moving, rod is free, ball links checked, 90 degree arm on tail,srvo arm centered. shaft inside boom, checked as best I could, doesn't appear bent, can see what that will cost and replace maybe, if my ebay sale does good, PHEW, so much time on just the tail yesterday.

The bearings inside the boom seem to be in the correct spaced apart method as shown in manual, previous owner only had one in the boom, but
I had one included extra when I got the heli, so I did put it in.
Had a time with the silicone trying to figure how to get the silicone on the bearing, used a little. Turned shaft while looking in it, and the bearing is not moving. They were a tight fit so I'm hoping there is not a problem with the bearings being only lightly glued.
That's a tough one to figure, how can TT expect you to get silicone on there or even Goop to stay on there and not make a mess?

Going to 3m tape gyro, in a few minutes. Found the outdoor
one at Lowe's.

You might wanna try different configurations. Try it with just the tape. Thats what it took to get my gy520 to work right. If one doesnt work try two pieces of tape. Then maybe tape plate and tape. Youll have to find the combo that works best. Do the mechanical setup on the tail in rate mode once heli is ready to fly. If you dont know how to do that, report back and ill or someone will explain. Also what TX are you using and gain values?TT X50 Nitro

I have the Radio, 7cap set to do Rate and HH.
Did the limits and mechanical on rate mode.
Got to redo it again to be safe.

The thing is this is the 860 Inertia.
It has a gain setting called Rud-Gain. The manual says Rudder stick gain. Fine tune the stick response to the actual piro rate. The higher the setting the more sensitive the stick movement.
The manual tells you to assign the gain settings in radio, so thats done.

Since I'm changing tape, I'm not sure where to reset the gain to.
I'm thinking, 45-50 was the least amount of shake area so maybe there
was even too high. Did read somewhere, that one guy had it at 37 degrees.
Ron said, make sure the engine is running a little less rich, I
told him the jeli was billowing smoke and it was. But I hate to run lean.
BTW, Ron's Heliproz rocks. One day to get parts. Wow, Wow, (you know the Borat thing?).
Damn raining today, last Saturday the same.
It's like an RC curse.

In rate mode, start the heli and go into a hover. If the heli yaws left or right adjust the tail linkage till it doesnt yaw anymore. Then go to heading hold. Readjust you tail servo limits in the gyro. Then see what happens.TT X50 Nitro

I don't know the Inertia gyro, but I suspect the gains you had used would be a good starting point.

Sheeit, almost a gallon and the wag is almost gone.Now we been on the tune up, with the 3 needles, it got confusing the other day and now James, has gone and ordered an OS 55 , with the 3 needles.
We got to be gluttons for punishment

Got one of the threads printed out, on the engine tuning, and I've gotten to where I think I can do a start up here at the house and adjust the needles with as little distractions as possible.
Been only flying at the field as it is easier to have 2 people to do the tuning. Unfortunately the GA gnats/flies whatever, are so bad lately, that it is almost unbearable to do any kind of work on the motors, because the bugs just swarm you if you stay still, for any amount of time.

Need to figure a "fix" for the bugs, because they are real bad this year, for some reason.

Same thing around here this time of year. They can be a real bother. Good to hear your getting close to eliminating the tail wag.

I switched to the Trex 600 / 700 V2b tail rotor assembly - 2 radial + 1 thrust bearings per grip.
And, it bolts right up to the 5mm tail rotor drive shaft
It will fit the 50 / 60 or 90 Raptor
