Help with set-up

[mustbnitro]

Looks like I know what I am getting, what about a 7XL, any links to a good 8XL or 9XL? I am looking at picking up the first two items on this link,http://www.starluckrc.com/catalog/index.php?cPath=52 would this be a good combo? I'm just not sure if the 7XL is alright or not. Thanks for all of the help, I am hoping to get the wheels turning by mid Jan due to a big event.
