Mirek, thanks for the great links! This will definitely give me another good reason to improve my Russian (I just need 36 hours per day, since I'm working on Jon's program)

Cheers,

Juergen

Enjoy: :-)

Mirek, thanks for the link to the 282 pictures, I filed them right away. My program is slowly making progress but the "Technical Papers, Books and Publications" section seems to be used by quit a lot of people, thank you for your supporting this idea!

So long,

Juergen

Hi Mirek, nice to have you on the friends list. I have been so busy getting my rotary wing math model to the next stage (add the gyro formulae) that I didn't contribute much to the rotary forum and almost nothing to the russian form (sigh... there's always to little time ....;-)
Have a nice weekend!
