LSP convertion....

Hey dudes my names Nick I'm new to RC monster....

I normally hang out at E-savage.com as i run a nice e-sav powered by a novak 4.5 and 14 cells...

I'm getting parts together to perform a BL conversion on a HB lightning pro-R...

So far i have a fiegao 9xl, quark 125b, UBEC, and RC monster heat sinks for both motor and ESC...

The truck will be arriving soon and i also have an RC monster motor mount on its way....

With the RC monster motor mount placing the motor where it does i do not think i will have room to squeeze 14 cells in the chassis...

So i may have to go to LIPO...I have scoured the forum and found that there are many different configurations that people use...

I'm just after some input on what type of LIPO would suit my application best..

I was thinking of going for 4s maybe 5s...i have heard that 6s is way scetchy with the 125b so i wont go there....i will try a 12t pinion first as my backyard "motocross" style track is very tight but big enough for 1:8

Thanks dudes...
