brushless help

[timaneli]

hello.
i am new here and i have a e-maxx 3905 full stock that i want to convert to brushless..

i have already see many option´s like single vxl, v-twin, novak´s.. etc and the list goes on....
i am not very experience on assemble brushless motors and esc´s so until now the best option i could find was:

this motor:
http://global.ebay.com/gbh/viItem?ItemId=160255613184
a feigao 7xl that is great for e-maxx..

and this esc:
http://global.ebay.com/gbh/viItem?ItemId=370041594514

i choose this esc because is cheaper than other´s like mmm or kontronik´s etc... and because come with a useful digital programing card and have reverse and bec, etc...

i have 2 pack´s of 7cells 4300 nimh´s bateries that i have to wire in serie, so with this motor and esc connect on 14 cells will i have a good and durable brushless combo?

my intentions are 80% bashing and 20%track..
and i can´t spent more than 150 dollars for now..
i am thinking going this kit because single vxl have heat issues and the esc is limited to traxxas motors , and novak is limited to novak too, so i prefer to invest is something upgradable..

give me your expereince opinions and if i will spent my money good on this parts!!

regards and thank´s in davance!!
