I've seen the TTS flycutter running on a PCNC 1100 at a show, and in one of the latest videos Tormach released. Any news on when it will be released? Couldn't find much about it except a mention here:
Tormach Tooling System: What
...and the video squaring an aluminum block using the flycutter here:

I was in the beta tests for the new fly cutter and did some extensive testing on the "SuperFly". It is very impressive. I compared it to the Glacern FM45-250 Face mill In both steel and aluminum the SuperFly had almost double the MRR using the same inserts. This is because the fly cutter is only turning 1 insert. Each additional inserts sucks up horse power. On a low horse power machine the fly cutter will win . I am sure if we were talking about a 10+ HP spindle the Glacern would blow away the fly cutter. But on the Tormach this fly cutter was far more efficient. The best I could do with the SuperFly in aluminum was a cut .035" deep @ 100 ipm for a MRR of 8.75 cu. in.( this cut was in the red ) The video below is .030" deep. The best MRR's I could get with the Glacern were 4.5 cu. in.( alum. ) and 1.25 cu. in ( steel ) The SuperFly got 2.125 cu. in. in steel.
The biggest drawback to this kind of MRR is the amount of chips distributed all over your shop !! If you look in the video you can see that I have cardboard extensions on the guards, they helped a little bit.
I talked to Andy at Tormach and he should have a blog post coming out soon for the SuperFly.

Any clearance issues for the ATC?
I do not have an ATC so I can't say for sure. The SuperFly does have an ATC Groove so it probably works fine.
Any idea what the minimum diameter will be? They mention a max of 3" on the website but no minimum.
I asked Tormach here is their reply:
The fly cutter radius is adjustable from about 1.25" to about 1.85". That is with keeping all three set screws on the tool bar.
I saw it working today at Little Machine Shop open house. All I can say is WOW.
You can buy good parts or you can buy cheap parts, but you can't buy good cheap parts.
