Or you could use the mCX one, although you will have to replace the blades as well, if I recall it well enough.

If you use the mCX parts, you indeed need the mCX top blades and flybar as well. Or get the Twingo one. Added that to the FAQ btw.

Thanks jtravel, already ordered a couple.

No serious crashes. Servos seem OK. It is faster backwards.

Much faster? What is the position of your elevator trim? Centered or a little far from the center?

A bit faster. It still levels out in reverse. It's as if there's not enough travel to maintain attitude. Elevator trim is a couple of clicks forward, i.e. down

Sounds a bit like the blade pivots on the lower shaft might have sheared off. Or swash plate came apart. Can you see the servos move? How far does the elevator servo travel down on full forward?

Does anybody know how to remove the outer shaft? I want to replace my swash plate. Any suggestions welcome!

Remove the gears. Pull out the inner shaft. Unsnap links between swash and lower blades. Pull the outer shaft up. It may be held securely in place by the ball bearings, just carefully edge it out. Unsnap the control rods from the swash, and there you are. You could leave the inner shaft in place, but it's easily damaged, so I would take the extra time to remove it first.

Thanks SoloPro! frieslander just walked me through the same steps. It is scary to apply force if you're unsure...

Pivots are OK, Swash is OK. servo travel ~3mm

I'm going nuts trying to analyse this, but here goes![*]I need forward trim just to hover[*]There's more reverse than forward motion available[*]There's more left than right aileron
It looks a if the servos aren't centred and are biased in one direction over the other. Is this possible? Is it adjustable?

You should use subtrim to center the servos, and then adjust the pushrods to make it hover with sticks centered.

How do I use "sub trim" mode? You mention elsewhere pressing a little button on the back of the Tx. There are no little buttons on the back of my Bravo III Tx.

You have to undo the antenna screws and flip it up to get at it. The switch is under the antenna.

Turn your TX over.
See the two empty screw holes, Look between them and you will see the round button.
