68mm Aluminum Alloy Electric Ducted Fan
I´m going to buy a F16 from Nitroplanes. Togehter with it I´m going to get the 68mm Aluminum Alloy Electric Ducted Fan (2185kv).
Do anyone have a suggestion for a good setup regarding battery and speedcontroller?

Yes I like my electronics to run cooler so I would get a 60A ESC since the weight difference isn't that much.

I use the "whatever I can fit" rule.
If I can safely increase the space for a higher capacity pack, I'll move up in size, even by as much as 1000mAh.
Since weight is being added to the nose, the plane will still fly.
A relatively small increase ( e.g. 4oz or so ) will be barely noticible. More than that means shifting things around or adding tail weights.

I prefer all of my packs to at least have a 20C rating, in case I decide to use them elsewhere later.
As I mentioned the biggest initial problem in selecting a battery ( aside from the voltage ) is "will it fit".
Putting in a larger pack than what comes with the plane may require some modifications by you.
So it is best to get the plane, and see what you can come up with.
On some planes I've had to cut the back of the battery "cage" off, to fit a larger pack.
In others cutting away a bit of foam, means that I can install a larger capacity pack.
But you must be careful not to structurally weaken the plane, nor to move the C.G. out too far.
Some C.G. change is often not noticible at all ( which is why people can walk around in full sized planes! ), but too much ( particularly towards the back ) can be highly problematic.
So check the measurements for a 3200 20C 14.8v pack, and see if you can find any way to cram something slightly LONGER and wider than this in.
Cutting out a block of foam to use as a test model also helps...
I normally have a bunch of different sized packs around so I fit and cut as I like.
