PLENTY of Questions about my BL Savvy

[Zcrusher]

I'm building up a brushless savage, and I have some questions.

First, motor/controller... I'll definately be running a BK 9920. I want to run 14 cells. What is the BEST motor/gearing for this cell config, and will I be twisting diffs?

Second... Tranny- What should I do with the tranny? I was thinking of leaving it and using the mechanical brakes to save my diffs, i hope. If that idea calls through, what mods are you guys doing to your trannies so they're solid and dont spin in one direction? Can controllers be set with NO brakes at all?

Third- Dabid reccomended Kyosho battery cups. Can these be used with the mechanical brakes?

Fourth- How are you guys meshing your gears when the motor screws are practically up against the tranny housing? Where can I buy a motor mount/ would anyone sell me one?

Fifth- I plan on running the 4 AA battery holder to power my RX/ Servos. Can i plug this DIRECTLY into the RX? Must I do anything to the controller after this? Also, what is UBEC and how is it utilized?

That should be it. Thanks :)
