It seems like the locker they use is more like CA glue. I had similar problems getting the heads apart on several HobbyKing kits I was building and needed to disassemble to grease and check everything. I needed to use a hot soldering iron to loosen the locker to. Remove the screws. Featuring shafts were the worst. Maybe customery in China to use CA.

That port is designated for the telemetry motor temp sensor. Would they use a standard channel for that.

Tool for locking screw on tail rotor assembly?

Just wondering what you guys use to tighten/untighten the little locking screw that keeps the tail shaft on??? It looks like a hex under a magnifying glass, but I don't have anything anywhere NEAR that small.....

If it's the same as mine it's a small philips head screw...any jewelers screwdriver set should have one that will fit.

Be carefull removing it though, the heads twist off those little screws easily so if it doesn't feel like it's budging with moderate force I would use a soldering iron to heat the screw first to soften the loctite.

It must not be the same - or we're not talking about the same one. This thing doesn't have a head, and neither does the one in the picture when you order the parts. It's the world's smallest little tiny screw with no head. It's like there's a little hex hollowed out - but again - I don't have anything near that small.

The only screw used on the tail shaft is part 46 in the diagram which goes through the plastic locking collar (part 45) and is a simple phillips head, it's not even that small.
If you quote a part number from the diagram then we know what you are referring to.

Honestly, this does not go through plastic, it's not a phillips head, and it IS even that small. If you don't consider this small, then I'm assuming that you could probably pilot this helicopter from inside the canopy - due to your freakishly tiny size.

EDIT: When I was saying tail shaft, I was talking obviously about the rotor shaft on the tail, since there's no actual "tail shaft". Sorry if that caused confusion. But back to the issue of this being a very tiny part!

Knowing how big that Tail Rotor is ... that grub/set screw is definitely small... Walkera aren't know for very accurate drawings either... usually it's V1 and since usually it's V1.xx that hits the stores there are some bits missing on the drawings.

Mono is right about it's number... but from the drawing and your pic it suggests allen head... not philips

This is listed as optional accessories, and they're also listed as "mental" gears....

Thats some very decent specifications on those servos. 2.8 kg torqe and 0.08s/60sec speed.
The gears looks like brass though on that picture.
