Tamiya twin gearbox problem

Yes, I'm using it, though in configuration D.  My wheels certainly
rotate independently.  I've also used a lot of other Tamiya products,
and found both the products and the directions to be of extremely high
quality.  I hate to say it, but my guess is that you're misinterpreting
the instructions.  They wouldn't put out a plan that locks the two sides
together.

Indeed, looking at the directions for A, I don't see any part that
extends all the way through the middle.  So I'm not sure what shaft
you're referring to, but I think whatever you have in mind there should
be two shafts.

Thanks, Joe.  I think you've got the "double gearbox", though.  I've
got the "twin gearbox" (doesn't have a D config).  For configs A and B
one of the shafts does actually go through the middle.

So I went through the instruction sheet one more time and right next
to the second lock nut it says, "Do not secure."  Doh!  It works now.

And you're right...very high quality product.

Oops, you're absolutely right -- I was thinking (incorrectly) that you
meant the double gearbox.


Glad you figured it out!
