and then click in "General Layouts"

It also uses 2 counter-rotating rotors as the Chinook , but very close one
to another

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 levels, one would slice the other's shaft... I'm puzzled.

But watching this helicopter thread has made me start wanting one of those
mini indoor R/C helicopters :-)

(...) 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)

(...) There's a small angle between the two rotor shafts, that's the solution. A clever one, indeed. Fredrik (22 years ago, 5-Feb-03, to lugnet.technic)
