Scorpion 2221-8 (3595kv). A Phoenix 35 will handle it ok, but you will need a separate BEC with it on 4S. Or use a Phoenix ICELITE 50 and you will get data logging as well as a built-in switching BEC.

im pretty sure stock motor/esc will handle 4S at least it did on a 450 v2 also you need less mah on 4s to get same flight times so look sligtly less mah also to balance weight issues you can add a full size servo for tail (9254 or something like that ()

If you want flight times, go with a Neu 1107H/2Y. I can get 6 minutes of governed 3400rpm on a 2200mAh pack. The Neu gives me a minute more than the scorpion-8 did at the same HS. Makes a heavy setup though, so if you're into extreme stick-banging, you'll have to run a high HS.
