One of the guys at the field had cut down a 700 boom and TT for his 550 but he used a TT from his Raptor with the screw down ends.

I believe the Align ends press in so you could drill and put a bolt through it.

I know that some Arrow shafts will work for the shorter tails.

Kalt Enforcer uses 550mm blades: I fabricated the TT ends on a metal lathe; use the Align TT ball bearing TT support offset near the middle; and 5mm dia carbon shafts (Easton). Never failed over thousands of flights at around 2200 rpm.

my buddy built one for me for a Century predator 90 going into a scale fuselage.

I bought some brake line and he cut it to the proper length. He then added the ends of a Predator TT and viola!!

It runs very smooth.

I've done this number of times...Aluminum arrows shafts. They work great and the cost is a fraction of the actual TT. However, you do need a sample TT, then cut the Aluminum arrow shaft, and then drill it for the TT end. On a rainy/snowy day, you can make up several to have on hand!

In the 90's it was common place for guys to build there own. We did it with custom boom lenghts for Miniature Aircraft fury's to run longer tail blades.

The arrow shaft seems like a common item, but where do you get the end pieces?

I have been saving ends for a year or so.
On its way to the trash, I use side cutters to clip them off.

I have read that Velocity 50 had TT ends are available as a seprate part.
Here is a link:
http://www.helidirect.com/r50n973b-...-50-p-23809.hdx
At $9.50 the numbers do not make sense to buy them.
Some small modification is required to get them to work on Align helicopters

Start saving them now, let your buddies know you want them, depending how often you need them, could be a month or a year before you will have enough to make your own TT's.

Most hobby places (that we buy from) will have them as a seperate item. If you need to buy a torque tube to save as a templet, get the full torque tube with the ends, then buy extra ends...providing they sell them that way. Then you will always have a ready spare TT.

Heli tubes
You can buy aircraft aluminum in different size tubes. Granted it is not carbon fiber but I think it is a bit more durable. I have used it on a older heli that I could not get parts for and it worked great.

Align ends press in
Actually, Align's TT ends are threaded in using a fine pitch, left hand thread. I apply some heat and unscrew them from busted ones. I can thread the tubing in my CNC lathe. I'm usually shortening them...like for stretching a T600 using a T700 TT and boom.

To customize the boom length. For example, I have a boom and TT setup for my Trex 600 to run 620, 690, 720 blades. And it works for Nitro and electric.
