[Romster]

I am going to upgrade my 1/8 buggy BL system.
It was a Hacker Master Comp ESC with Feigao 9L on 12 cells
Up Grading too..
-BK Warrior 12020 esc
-UBEC
-Lehner 1950 BL
I want to run 14 to 16 cells and go to li-poly in the future.
I'm thinking Lehner 1950 5turn.
Need some input guys....
I have the ESC/UBEC already can't seem too decided on motor turn..
