Some more questions... which one?

[jnev]

Thanks for the info. I am now leaning toward the 9xl. But would it be safe to run an 18t pinion? Will this be too over geared and cause a lot heat? As of right now, this is what I need to buy:
1) Feigao 9xl http://www.rc-monster.com/proddetail...WAND_XL&cat=20
2) UBEC http://www.rc-monster.com/proddetail...=6vubec&cat=21
3) Rc-monster heatsink (XL size and black) http://www.rc-monster.com/proddetail...d=RCM01&cat=20
4) 5mm mod1 18t pinion http://www.rc-monster.com/gears.php
5) True-rc 4s2p 8Ah pack (anyone know if Mike can order one?)

I went with the 8000 pack because I really need a lot of run time. I'll only be running 1 battery for the time being, until I can get some extra cash for rc's.

Thanks
