Default Pinion lenghts

Beware if you change from Gaui pinion to Scorpion.

The Scorpion is like 2mm shorter. I had grinded a little on the main shaft for the lock screw and now it barely locates good axial-wise. Just edge to edge w main gear, would need to move it 1mm but can't because of the grinded slot (if I don't want to grind some more that is )

Well. Just a notice.

Those pinions are hard to find. I tried finding them and i got one from innovative designs, they were awesome.

But finding one online,,,what a pita. But i asked for it, early adopter syndrome

I am using the scorpion 13t no issues.

Also here is a pic of the new TT bearing position, says edit ** 2cm off center , either direction.
Just not centered, and not as the manual says.

JC, can you please ask Gaui to ammend their manual, about the TT bearing position. Doing this has made a big difference to my X3. Thanks.

Thanks. So no change about the TT bearing location and when were they going to tell us about this mod. I'm starting to get annoyed now:

Edit: I see now it's only if you are using the collars on the TT.

I just found a easy way to change a TT carrier bearing. Just pulled the boom back, used a L wrench and pushed it back out. Then used tweezers to place the new bearing on the guide pin. And pushed the boom back in, it went really easy.

I thought i would have to remove the lower tray, or a side frame. I dont want to pull cutting screws in and out of plastic alot. Well not anymore that i have too.

I roughed the one way assembly up where you glue the two parts together with 120 sandpaper. Do you think that is ok or should I take it apart and rough it up more. Don't want the oneway to fall me. I have enough troubles keeping these things in the air without the heli being the issue.

Thanks

Bill

Finally started on my X3 kit. I am extremely careful but managed to strip the plastic where a M2 bolt is used. The self-tapping screws are more forgiving. So...a simple tip that has been mentioned before is to use caution.

Second thing...I noticed the mainshaft bearing blocks/servo mounts contact the carbon on the lower rear mounting point. Simple matter of trying to fit a square edged part into a radius in the carbon. Hard to explain in words. Easy fix is to chamfer the edge of the bearing block rather than force the fit.

Third thing...something is making my frame slightly unsquare. With bearing blocks alone, it's square but once I attach the battery tray and ESC tray, it's a little tweaked. Yes, I have an OCD problem. I suspect because the screw holes in the frame are very precise, i.e. somewhat snug fit, there's no wiggle room and this torques the frames. Still working on this...

I just finished the installation of the main gear assembly (p.10 of the instructions).

The way I handled the installation of the two thin washers was to invert the heli, insert the main shaft so that it barely emerged through the upper bearing. The two washers could then be slid onto the end of the shaft. The gear assembly could then be slid into place without the two washers moving. It was very easy this way.

(As MinskUK and scoio have already mentioned, the screws holding the lower bearing mount

needed to be loose so that the gear assembly could easily slide into place---then tightened afterwards.)
