Cool! I figured that the stiffness of the wire would help. I guess I'll call
it Shorty ,as it's only a little over an inch tall :). Now I've just got to
get that micro motor ordered so I can try it out myself. I'm wondering if
you could try out a slightly different design for me. It wouldn't use the
block under the motor (because as you said, the wire helps more than it
does) and it would use a 1x7 bent liftarm connected to a 16 long flexible
axle or flex hose of similar length. You could try it without a brick under
the motor or with a 2x2 plate there. If you could let me know how it works
out, I'd appreciate it.
Thanks,
jrl

| ...and then they were five... The 1x7 liftarm is a bit short and the motor bumps against the flexible axle. So I used a 1x9 (7+2) to be low enough, and I could remove Micromotor bottom. I used a 1x2 liftarm with plate only for aestetical reasons... (...) (21 years ago, 5-Apr-03, to lugnet.technic, lugnet.robotics)
