Avant Aurora - EFX - FX > Tail Alignment
 
 
Doug L

Location: Minnesota

So far the build has been fairly painless with only a few hiccups. (1 bad bearing, 2 missing bearings, and a tweaked, but usable main gear). I'm installing the tail boom today using the small holes (3 in the back, 2 in the front) to align the boom, but the tail shaft is definately not level. Would there be any problems with enlarging the holes at the front of the boom so it can be spun? Are the tail boom clamps at the front supposed to touch at the top and bottom when it's tightened down?

Mine was off a degree or two, just like yours.
I loosened the boom clamp, and twisted the 2 degrees I needed.
No problem.

My boom clamp pieces do not touch.

did you install the plastic piece that belongs inside the boom? I would get in touch with Avant RC for the parts that weren't right. I guess one of the changes to the kits is that the boom can now be secured with a screw from the frame.

What plastic piece? I don't see no plastic piece.

In the molded plastic boom block, there is a little tit that fits in a hole inside the boom. That keeps it in alignment.

The hole in the boom doesn't allow for a whole lot of play for that tit.
It was just enough to get the tail aligned.

Only screws in the vicinity of the boom are the 4 screws that mount it, and the PEM nut that holds the rudder bell crank.

Doug,

You could enlarge the holes if you wanted and it would make no difference but we can replace it with a new one too if you like.

carcrasher has one of the prototype units and he's referring to the old metal clamp that needed a plastic front insert to minimize the cracking problem we were having with the metal boom clamps.
The release plastic boom clamp made all that unnecesary so what he was referring to doesn't apply to the release kit.

Augusto.

Man, a lot of changes were done to the kit. Sorry if I confused anyone. i didn't know this(the "plastic cap" was no longer needed.

I loosened the clamp before the picture and this was as close as I could get. If the holes are punched right the system is pretty cool to be sure that the boom isn't in too tight to compress the torque tube, and it shouldn't be able to slip or spin once assembled.

Tonight I'm putting in servos. Someone had mentioned earlier about putting the servos in before the frames were attached. I wish I had listened! Some of the braces, start shaft bearing blocks, and radio tray needed to be undone to pry the frames apart enough to squeeze the servos in through the center. It's all growing pains and is to be expected. The fan shroud is perfect as are the metal components and carbon.

No! You dont have to loosen anything! You're just making harder for yourself than it actually is.
There is no need to pry the frames apart.

Doug, I just created a thread called HOW TO: Servo Installation.


You'll be amazed how easy it is to get the servo's in after you've done it once or twice.
I don't suggest putting them in with the frames apart, especially if you haven't done it before.
It's important to know how they go in, because its the same way they've got to come out. You'll just have a harder time, IMO.

I had an Avant EFX before this, and all I can say is that installing the servo's on the Aurora is A LOT easier, since I think the slots are just a bit bigger.




Anyways, be sure to leave this opening for last. As you can see, you need this opening to access the screws.

I have the same problem...

Assuming I could remove the plastic alignment nipple and just rely on the clamping force of the plastic on carbon. I would then have to re-drill the holes in the "tail case" end of the boom, as only 2 holes line up with the tail case.

Basically none of the drilled holes in the carbon boom are in the correct place

Slot the screw holes in the boom mount side (front) of the boom with a round file.

Thats the best and easiest way IMO.
It really doesn't take much.

If you think about it, the holes in the boom are misdrilled by only about .5mm.

The front of the boom I could deal with, but when only 2 out of 3 of the boom drill holes (tailcase end) line up with the tailcase that becomes a problem. I would need to re-drill the carbon boom...

Ah, ok. I understand what you're saying. Fixing the the alignment in the boom mount is only half your problem.

I would send an email to Avant RC's customer service aurora@avantrc.com
