AM14u2 Drive Train Unstable
 

Greetings,
We are currently experiencing issues with our AM14u2 Drive Train, concerning the center whee,l which has proven unstable; an eighth of an inch lower than the other wheels. Is anyone else experiencing this problem?
Thank you!

Yes, this is normal.
The center wheel is lower than the outer wheels on most 6-wheel drive set-ups to allow for easier turning.

See this whitepaper for why this is.

P.S. Welcome to Chief Delphi!

Hi there,

The center wheels are dropped .140" by design to allow the chassis to turn. It reduces turning scrub of the chassis overall by reducing the effective wheelbase.

That's a feature, not a bug. :)

Basically, by having a dropped center wheel, you get the stability benefits of a long wheelbase, with the ability to turn of a wide wheelbase. The 1/8" of "rock" shouldn't interfere with your ability to play the game at all. If your mechanisms require that much precision, you weren't going to be very good anyway...
