anything else

[tonka truck]

Just a q about my setup. I have decided to get a lehner 4200 and mgm120 for my losi xxxt 1/10th stadium truck:D . Are there any other hop ups or accesories that anyone would recommend in light of my brushless setup?

I am thinking of getting 7 cell gp 3300 or the IB 3600 (however have not heard much about these cells). :P: Side by side or stick pack??

I also wanted to know if there was a particular place on the chasis to mount the esc, e.g. rear shock tower, on top of the batteries...?
