Possible brushless setup (your thoughts)

A made a thread a couple days ago on what would be a good buggy to convert. i have decided on the Hyper 7 tq black. Now, as far as the setup goes... i found a $60 radio that has $25 receivers sold seperate. I would run the stock servo, rcm motor mount. I'd like to run a MMM esc, and a 80mm medusa on 6s zippy from hobby city. Looking for your thoughts on the setup... things to improve on, etc. Also, just to make sure; can the hyper 7 DL handle the 6s? i know it will be crazy, but hopefully it will keep me entertained! Looking for your imput... Want to make sure i get this right the first time.

On a side note - i made $15 on easter, and $50 today for helping my grandma. I have to ride over to my grandpas to pick up $40 for my work over there too! That's over $100 saved so far... Plus i am going to sell my phone, and maybe a rc. the stock kit is only $300 minus what the nitro crap sells for. On my way!
