who is flying a IV with T3 tailwheel?

[culater]

I have one but not installed yet. I have seen other 4's using them. You will need another tailwheel that accepts a 1.5" tail spring on the T3

I have one, you can fly to felts and see it first hand

John, my T3 did come a bit different. That part you have is now a machined aluminum part but they still use AN3 bolts. The aluminum is thick so except for the threads, the bolt shank is fully captured within the part. I did have to use shorter bolts than what was included.

The design of the T3 rear mounting bracket that I received wouldn't allow anything longer than the AN3 bolts that came with it, and those were slightly shorter than they should be (not quite enough grip length). I think the design of that bracket might have been changed on later examples. I wanted to increase those to AN4s at the correct length, so this is what I decided to do - I drilled everything out to 1/4" for the AN4s, then reamed the holes in the bracket to 5/16". I then made some bushings the correct length for the bracket thickness. Now the larger, longer bolts can be inserted, followed by the bushings, to give a good fit between the bolts & the oversize holes.
