Hello,
How are you progressing with your J-2 project? I am out of luck finding original MR blades.
I checked with "04 Marine" on PDF drawings for J-2 gyro, but unfortunately his PC crashed and he have to make a new copies. Though he told me that you may still have one copy. Will you share it with me?
I enjoy your posts and find great interest in your knowledge of all aspects of the sport. Keep up the good work and hope all is well with you and your family.
