From the behavior of your motor, I'd suspect a slipping one-way clutch.

As to the tracking, are you using the original woodie blades, or have you since installed fiberglass or carbon fiber ones in their place? If the original woodies, you may have a blade that warped over time.

If you still have tracking problems with decent blades, and after you make sure the feathering shaft is OK, you may have some bad thrust bearings in the head like these:

Those were from one of my Caliber 30's whose head was acting "wonky". You may also want to make sure you've got those thrust bearings installed correctly -- race with the larger inside diameter hole goes closest to the main shaft, the race with the smaller diameter hole goes furthest out from the main shaft. You may also need to put in some new grease. Suspect a bad radial bearing or two in the head, as well. This can cause a head to give you fits when trying to track the blades.

My Calibers when in good repair, never exhibited tracking difficulty and were relatively easy to track after a repair.

I'm not sure you'll find an "upgrade" head as there just never was any abundance of aftermarket bling for the Caliber. "Correct" made some upgrade parts, but they were expensive and not widely popular.

If you can find some new dampers, give those a try, as well. Don't forget to lube them and the spindle when you reassemble.

Now that you mention it, slipping one-way bearing would show the same symptoms that I'm experiencing. Never thought of that or would for that matter.
Gee, thanks Doc

My blades are TT 550 Carbon Fiber blades and I've checked them for warping.

I just checked my feathering shaft and I can see a very tiny movement in the other blade so gonna need one of those too.

As for my trust bearings, they are ok, they do not look like your picture but has a smooth ring all around.
And they are mounted as they should, had to get my calipers out because I could not see with my own eyes the difference in size.

But, when I disassembled the head, one of the bearings, the one closest to the head, the shielding came off.
I just snapped it back in place and it was good again.
Not sure if that could have anything to do with it.

As for upgrades, I didn't mean the entire head, just the slide block.
I'm pretty sure I saw a CNC one around when I just got the bird.
Most likely Chris had them but not anymore.

Edit:
Err, I just saw what you meant with radial bearings.
I thought you mean the one on the main shaft and that I had to split the frames aka lots of work

Well bearings are cheap and widely available so I'll just get a new one.

Well Christmas came early this year.

Took a while to get them but worth the wait, and excellent service from RC Japan .

Now I'm off to build.

Right lads, I'm finally getting somewhere.
Its been built and its been flown.

List of repairs/upgrades:
  • Changed spindle
  • Changed dampers
  • Changed 1 bearing in grip
  • Changed one-way bearing with HG one
  • Replaced washout block (thank you Quest for using hex bolts. makes tightening it sooo much easier when doing phase adjustment)
  • Replaced ALL the links in the head with beefy adjustable links for the C3
  • Added HG EMS plate (it was cheap so I figured why not)
 
  
Look at the bling bling!

 

Oh, and when I said it was completely stock I lied.
I actually have the HG Main Gear.
Got it when I parked it in a bush way back cause the LHS didn't have the plastic one.
So now I have 2 pieces of bling, but this latest addition actually removed massive amounts of bending in the servo tray, well worth the money.
 
 
 
Field report.
Got there, fueled it, range checked, started after 3 seconds, purred like a kitten as usual.
Spooled up, tracking was a tinsy winsy off, adjusted link half a turn.
Spooled up, wrong link, it was worse, land, readjust, half turn on other link, spot on!
No slipping what so ever on the one-way.(thank you yet again Dave for pointing this out)
Had a wobble, adjusted my hover slider on the tx, buddy tached it, 1800 HS, Jolly good!
The tail was a bit spongy so I played with the gyro sens but even at 75% it still was spongy but then my buddy said something completely unrelated but it got me to think about tail blade tension, so I landed and tightened them and voila! crisp tail.
But it still wagged a bit, even at 60% sens.
Not too sure about that.

Now I still had the occasional wobble but I just had to land it for a split second and it was gone for a while.
I'm thinking it is the play in the washout, even the brand new block had (what I consider) huge amount of play.
Need to find something to sleeve them with and try again.

All in all I'm pretty happy I'm getting somewhere.
I am planning on flipping the grips back to the "Advanced" position because it feels sluggish.
Maybe then I can get a symmetrical pitch curve.

Not in a hurry, its going to rain for at least 1 week.
Always when I feel I get progression the nature f**ks me over
And its getting darker earlier every day.
Anyone done a night flying caliber?

I have lights and night blades for mine!
Coffee stirrers work for the sleeves.

So I did the grip flip but still didn't get the symmetrical pitch curve I wanted, it was even worse in fact.
So since I now have a fully adjustable head I made sure the bell cranks where 90 deg, ignoring the servo position and checked the pitch again.
now it was something like -5 +20 (good for drag racing perhaps?)

So I shortened the links from the bell crank to the swash with about 6mm and now it's at -11.7 0.2 +12 and that's close enough for me.

Reduced the AFR pitch a bit and its now at -10 +10 roughly.
Might have to reduce it even more, not sure how much the .32 can manage.

The only thing is that the washout is not level at 0 deg like Dave says it should be.
Should I address that? I'm just happy the pitch is symmetrical for once.

And I also sleeved the washout pins and its rock solid now.

Tomorrow there's finally some good weather and I plan on using the entire day flying, even if I have to wear full arctic gear so I don't freeze to death

10 to 10 is probably max pitch for the 32. Mine is like 12-12 and it bogs pretty good unless I have perfect air!
I don't think that I've ever checked my washout at 0 pitch but I don't think that it matters that much as long as you ptich is symmetrical.

Sounds as if you're good to go. +/- 10 is about all that poor little 32 can handle. Happy flying.-----

woo!
I brought it back to life.

Flew a total of 1.5 gallons of fuel this week
And more to come tomorrow/sunday/monday.

There is only one issue left, and its a weird one.

When I start flying the tail is rock solid but as the tank nears empty it starts to wag pretty wide side to side.
I got no explanation for this behavior other than that the engine might get leaner near the end but the tune doesn't change at all.
One guy on the field said to lower the sens but its already low imo. 65% seems pretty low to me but I have adjusted it to 60 so I'll see tomorrow.

On the subject of tail, if I do smooth turns it seems to notch around.
Like, I hold the rudder at a constant to one side and it does tiny steps instead of a smooth constant turn.
No clue about that either but might be tail belt or something.
But if I whack the stick it does a 90 deg turn just fine and it stops on the spot, no sponge action there.

Probably just have to accept it but I feel I'm not as 'connected' to the heli as I want to be.

EDIT:
Ooh, I stumbled upon this thread and the second post said
colder weather causing boom to contract.
Might be something along those lines, its been pretty cold when I've been flying.
Like 6-10 deg Celsius.
hmm, gonna wait for replies.

Bumping again.

Fixed the tail issues, I just moved the linkage one notch in on the servo horn.

Well.. fixed and fixed..

It doesn't wag anymore at all.
Two things I have induced tho.
1)
I don't get full deflection on the tail slider even with the limit on the gyro all the way up.
I think that's why I moved it out in the first place.

2)
If I hover in front of me it drifts left sometimes.
Doesn't matter if its windy or not.
If I come in from a circuit and let the heli drift sideways into a hover in front of me it stops just fine but then the tail starts drifting and I have to counter on the rudder a bit and then it holds fine again.

It isn't bad, just a little annoying.

Weird part is it doesn't do this when inverted for some reason.
Or I'm just not paying attention because its bad ass to fly up side down
