it would be scattered, the video i posted was with a 7.2, 1800 nicd, 15turn double, team orion with stock speed control. It runs good and is pretty quick and gets good run times, it would only be longer with a better mah battery. You can run an 8.4 too but why take a chance. I know clermontmotorsports.com carries motors but towerhobbies.com has a large selection.
