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.

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.

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 the time right now :( I might have the Technic parts,
though...for a simple one with no rotor controls... ideas are going through
my head....and I don't have time to build it :(

Of course, I'd use non-LEGO material for the rotor blades, attaching them to
a leading edge made out of Technic axles. Is this cheating??

(...) I am working on a couter rotating design using axels and a non lego covering as rotor blades. I don't think it's cheating if the "works" are solidly lego based. Paul (22 years ago, 6-Feb-03, to lugnet.technic)
