I'm in the process of completing my build for and have encountered a problem.
The tail case is not aligned to the main frame nor the fron torque tube gear case, the whole tail assembly is slanted about 2mm to one side, it is visible to the eye, and I corroborated the misalignment by pacing a bubble level in the tail case and in the front torque tube gear case and placing the whole assembly in a leveled surface.
I have tried both booms that came with the kit thinking it could be alignment holes in the booms, but the results were exactly the same.
The tailcase case a design which won't allow any corrections as there is an alignment pin which goes into the boom...
Has anyone heard about this issue before, what would be the procedure to correct it?
I have concluded the hole in the tail case is not at the center, but slightly off to one side, should I enlarge the whole in the tail case, or the hole in the boom, does anyone knows if Align offers any warranty? If I enlarge the hole, the whole purpose of the self alignment goes away...

Thanks a lot in advance for your help guys...

It's a common and well known problem that should have been sorted by now,

Just dremel the hole on the gearbox end you only need to just touch it.

Rightfully, it should be less obvious with the al boom.

You will need to open up the "U" shape cut out at the front end of the boom which goes into the tail boom mount and prevent the boom from twisting. After you enlarge that slot slightly and twist the boom back to alignment, pin the tail boom to the boom mount. This prevents your boom from flying out/twisting in flight.

What is pinning your tail boom? This is.

Thanks a lot for the input... I had actually thought of those two sugested processes for fixing the error, hadn't thought about the pinning, that is a great idea.

Just one question with the pinning, how do you hold the screw? Does it go all the way to the other side and is held with a nut on the other side?

It sucks that being a know and common issue, Align hasn't done anything to fix it...the bird has been in the market for some time now....

Question on the 2 tail booms included in the KIT
I have a question the two tail booms in the 700 nitro pro. One is aliminum and the other is not mentioned anywhere in the manual, and sold everywhere as carbon ?

Today i had to do an ugly low level auto in alomost 20 - 25 miles an hour downwind because i didnt pin the tail boom. thjat was my fault but after looking at the tailboom that i taught it was carbon fiber, its aluminum cover with tin sheet of carbon for just looks.
Is there a real full carbon fiber tail out there or miss labeled ?

That is the selling point of the boom...CF wrapped around Al for the balance between strength, weight and durability...

No. Do not put it through to the other side for you will damage the torque tube...just apply a drop or two of thick CA on the screw.

The slot in the slot in the front of the boom usually allows enough room to twist the boom and straighten the Align_ment (Pun intended)

I also notice lots of people that have boom loosening problems are not getting it slid ALL the way in at the front mount.
