If you want to keep price down go with true rc http://home.comcast.net/~truerc/read....htm#Car_packs
If you want high end go with something with enerland cells here is another great link for more info http://www.rc-monster.com/forum/show...light=enerland
Will you be raceing in red deer? hope to see you at the track I got membership today it will be my first time racing.
Why a 2s pack you might not be happy even with doubleng them up in your bigger 1/8 why not a 3s just run a single in th .5 and double up for 6s in the 1/8.
My self I will be running 5s in my x1crt
