Just ran across this thread, and decided to chip in. I am building a TF Spit as well, and have it framed up and am getting into the tedious mechanical hookup stage, minor details, and then will be ready for the glass and paint. See the pic for my Spit in bare bones.

I completed the TF FW190 last winter (pics on Wulfman's site), and flew it all summer. What a joy to fly for a warbird! I hope the Spit flies as well. They should look good together in the pits.

I did not have any real problems building the Spit, errors in the manual and all. Most is common sence and thinking things through. Then again, this is my 4th warbird. in the last three years.
