did you mean 9s2p when you said 6s2p? 5320/28 will be happy between 8-10 lipo cells.

CC80 is only design for upto 6s use although i've run 7s with it (void warranty). I have been using Jeti 77 opto for all 9s uses. 2 things I don't like about jeti is that it lacks soft start and warranty is for 2 month only. New CC HV series is just what I've been waiting for.

For your funtana, I would go with 19x10e or 20x10e prop 20x8e hovers better but it feels too slow. tanic 9s2p 5000mah pack should be fine. You can go with Jeti 77 opto or New ( not yet avail ) CC HV 85 ( noe bec ) and you will also need a Ultimate BEC 6v version for receiver power.
