Ron Sieck's award winning Classic.
 
I spent 14 years and over 6700 hrs. flying this Grumman 600 Ag Cat. This is where my love for biplanes came about.

Hatz Classic # 41 construction
We intend to use this venue to record all activities related to the construction of Hatz Classic S/N 41. It is my hope and desire to be of help to the next builder who may run into issues as so many have been a great help to me already.
My inspiration to build the Hatz Classic came to be through a good friend who built a Hatz CB-1 and incorporated many of his own changes into his airplane that are similiar to the Classic. His award winning aircraft "Parsons Persimmon" is the result of his craftsmanship, skill and knowledge.
