"Well, if there is no need to run two then I'll just buy the CC setup. Ultimately would you say thats the best? "

Yes...............it is of high quality, and has great support. I have had two products warrantied by them, and one was a year old! Dont worry, i have had more than two of their products so their quality is good in my opinion. You can get the 2650kv or the 2200, both very powerful, the 2200 is rated for 6s and the 2650 4s. The 2200 is more powerful and will be faster on 6s.

Top speed is around 60.
