Interesting on the need for a block on the front attachment point.
What tire size are you guys running that need the additional block?
Is this block added to reduce/eliminate shimmy due to too little caster?

Pete,
Yes, I see you are reducing the positive castor angle with adding the forward block (and slightly increasing the amount of trail).
What problem are you solving with this? I will be setting my T3 up soon and am very interested in this. I will be on 8.50 x 6 tires, standard fuel tanks, 160# pilot.
A brief discussion of the geometry here for those interested:

Mainly ground handling, there is so much positive caster that the TW wants to flip around 180 and its pretty much a balancing act to keep it centered. Once it’s loaded and you have some elevator pressure and forward speed it’s not as bad. You only need a few degrees of positive caster to prevent shimmy, I didn’t measure it but if I had to venture a guess it was double digits originally. I have mine set up as light as I can get it without loosening the spring to the point of it rattling and have no issues with shimmy when loaded.

Reviving and old thread with some questions.
1st: everyone still like their T3?
2nd: Airframes website lists the T3 at 5.2 lbs. Does anyone know the weight of the 2 leaf springs on the CC setup that the T3 would replace? I called Airframes and they didn't have an answer.
3rd: I noticed that the chains go slack on compression when watching their video. I assume once the tail is not compressed that the chains are taunt again and can enable ground steering?
Looks like a great product. Thanks

Here's another great shock tail spring that many of us are using.....

Thank you, yes I'm aware of the Acme Stinger. I happen to run the Black ops on the mains.
One better than the other?

I cant say if one is better than the other, as Ive never had any reason to move away from Acme, both for the Gen 3 Black Ops and the Stinger. Awesome engineering, durabilty, light weight and form factor..... all of my Carbon Cub customers are using them.
