Custom gearbox for savage (center diff)

[spiftacu1ar]

I started a thread a while back in the slipperential section, but it really belongs here in the savage department: http://www.rc-monster.com/forum/showthread.php?t=20266

I am basically making a custom gearbox for the savage which accepts most center diffs (although it really made to be used with the sliperential). It can accept a wide variety of ratios, accepting pinions of between 9 and 16t. (more if you use a 46t spur, the details are in the linked thread). I am running CEN diffs and 40 series wheels, so 50:9 or 50:10 is the ratio I will use.

I will be making myself one this wednesday on a rapid prototyping machine (printing ABS plastic, so its pretty strong, ready to be used).

I am wondering if anyone else might be interested in such a gearbox. Also looking for comments about it.
