Savage 25 BL Conversion - Need Help

[tank_taxi]

Hey guys I'm pretty new to this forum, but definitely not new to rc. I currently have a Savage 25 (moderately beat up) that I ripped my OS 30 out of to make it a BL. I have a Feigao 8xl right now and am going to get a MMM soon enough.

I have stock 2-spd trans (locked into 2nd), the kershaw savage BL motor mount, 47t spur, all else is pretty much stock.
I'm planning to: lengthen tvp's to accomodate 2 x 3s1p lipo or 18 cells nimh in stock motor plate area, Medusa 36-80-xxxx/CC Neu 2200.

I wondering what you guys think, if I should use the savage trans or a center diff, and if there is anything else that should be considered.

...go with what ya got, get it running and then you will start to see what you want to change ;) Keep us posted...
