In Matt's post about his plane developing cracks and saying it made sounds during pull tests. While reading my Stunt News I found tow articles that I thought very interesting. One pertaining to what could be part of Matt's problem and one I want to try on my new plane.
May-June 2011 Stunt New page 16 has a picture of Bob Whitely doing a pull test. Will have to try that method in the future.
Page 42 is an article on removable tail wheel. Also love all the color photos.
