| | | (...) Hi Luis - Checked out that page, and the experimental helicopter you have shown seems like an impossible setup. How do the two rotors, the way they are mounted, keep from chopping each other's drive shaft to bits? Even if they're at different (...) (22 years ago, 5-Feb-03, to lugnet.technic)

| | | | | (...) The shafts of the rotors are angled outwards. Look at the pictures on the general layout page. There's one of the machine looking from the front- you'll notice the shafts are angled. TJ (22 years ago, 5-Feb-03, to lugnet.technic)

| | | | | | (...) Ohh, thanks! Now I see it. I didn't notice the rotors themselves were tilted, I just thought that was the style of the covering around the shaft. I think now I've caught the bug -- I wanna build a Technic helicopter too! But alas, I don't have (...) (22 years ago, 5-Feb-03, to lugnet.technic)
