  Dear Pitts Gurus:

I've seen talk of an "H" tube on Pitts aircraft that often needs attention. 
What part of the aircraft is this and what do I need to look out for as I 
shop for a Pitts S-1S regarding this "H" tube?

Also what do I look out for regarding the control stick. I have seen mention 
of a requirement to check for cracks and a fix for this.

Thanks again!
Paul Klusman

P.S. Thanks again for all the folks who responded to my "Pitts groundloop 
damage" question. I looked at the plane in question tonight and I'll probably 
not buy it. I think the plane is in good shape but not quite as good 
cosmetically as I'd like.
