Hatz Biplane Association

I'll check when I get home, but if memory serves there are additional pages for:
Drawing (3-view?) of the Classic with the R3600
R3600 engine mount
Lengthened landing gear

I'm guessing they are based on the work done on your Classic.

OK, I was right. The extra pages for the Radial Classic (as he calls it) are:

Page 00-R Two View drawing of the radial Classic
Page 17-R Gear Leg
Page 23-R Engine Mount


When I emailed Jeff I had pages 00 - 22 and 25. He sent me pages 23-24, 26, 27, plus the extra pages for the Radial Classic I noted above.
