Hello Marty,

My name is Dan Ulrich and I have been working with Devin York in restoring the Ultimate plans and bringing them back to life. We have currently got the 10-200 and the Pitts S-1S conversion plans done.

Since we found each other we have been trying to get these things sorted out.

We are also looking at getting the 10-100/150 and the 10-300 plans together. This will be a little harder then the wing conversion or the 10-200 plans.

There is a lot of interest in this. We are advertising on the barnstormers website and are looking at taking out space in Kit Plane as well.

I thought your web page was well set up and quite detailed. It's been interesting catching up on the recent history of this plane. When I worked for Gord in the mid 80's I knew he had a good design, It is unfortunate that the company wasn't able to make it. I'm doing my part to help revive an excellent piece of avation history.

keep up the good work.
