    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?

    Iím only running 26 airstreaks, itís to reduce the positive caster angle.

    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 itís loaded and you have some elevator pressure and forward speed itís not as bad. You only need a few degrees of positive caster to prevent shimmy, I didnít 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.

    Thanks for the heads up. Contacted Airframes AK and they are sending me the low angle bracket (p/n ABI-51349)
