 | | Any Ideas= 8448 and 4 wheel steering?
|
|
Hi, I've been thinking about this for about a week and can't come up with anything. I even looked at the 8880 instructions but I couldn't figure out how to make the conversion. Does anyone have any ideas? Any Help Apreciated! Thanks! Gary (25 years ago, 10-Jan-01, to lugnet.technic)

8456 had the fiber optics, but is hard to find. The micro motors were available as a service pack. That way you'd get the proper brackets to mount it (top and bottom, rather than two bottom pieces like you get with the space shuttle). Check (...) (25 years ago, 10-Jan-01, to lugnet.technic)

Chris, it depends on your point of view. As backlash gets less and less, gear train friction gets more and more. The friction is somewhat between the gears but mostly in the shaft bearings where additional force comes to bear. Unless you need (...) (25 years ago, 8-Jan-01, to lugnet.technic)
