Glad to hear that worked out right. Sounds like your YS wants to really fly, and doesn't like having the drag of an airplane behind it.
Your Spacewalker has the same problem as mine. No pilot daring enough to hop in for a ride. A friend of mine who couldn't stand to see that empty cockpit recentlly gave me a G-man pilot bust to put in there (his cheeks are all blown back from over G). I have a little hangar rash to fix, and then I will put him in.
