Not sure what size battery for this setup

[sumone]

I'm still fairly green when it comes to this stuff & have never scratch built before
I recently bought a few cheap items from china

i got this setup.
1400KV Outrunner Brushless Motor + 30A ESC 1045 Propeller

A2212 1400kv Motor Specification:
KV: 1400
Max Efficiency: 80%
Max Efficiency Current: 4-10A (>75%)
Current Capacity: 12A/ 60s
No Load Current: 0.5A
Number of Cells: 2-3 Li-Poly
Motor Size: 27.5x38mm/1.08''x1.5''
Shaft Diameter: 3.17mm/0.12''

30A Brushless ESC Specification:
BEC: 1A / 5V (Linear mode).
Output: Continuous 30A, Burst 40A up to 10 seconds.
Input Voltage: 2-3 cells lithium battery or 5-9 cells NiCd/NIMh battery.
Max Speed: 210,000rpm for 2 Poles BLM, 70,000rpm for 6 poles BLM, 35,000rpm for 12 poles BLM. (BLM: BrushLess Motor)
and a few cheap rx's

I banged together this rough lil plane .



but i'm not sure what size battery would suit with the included prop.

I also bought a cheap 2200KV Motor Outrunner Brushless.
would it be better ? and if so what size prop and battery?

Thanks in advance.

I'd go with a 2200 3s

If you find the 2200 is a little too heavy you could easily go for around 1300mA 3S 20C

Unfortunately you have not give any aircraft weight of where its CG is and what weight is required for proper balance point.

The main selection criteria are weight, capacity, required flight time, Current rating, availability.

Have Fun!

I tend to go lighter with my LiPo's preferring to fly about 7 minutes or more, landing, and then swap out LiPo's. Therefore most of myine are 1000-1300 mAH though I do have a few 1800 and up because sometimes I just want to cruise longer and the weight is less an issue or even preferred (like when CG is a factor). The capacity depends on what you need/want but is the most flexible aspect.

On the C rating though I like to keep mine equal to or slightly greater than the ESC amperage. In your case I would choose a 30C or 35C.

I would use the 1400 kv motor on that plane with an 850-1300 mah, 3s battery. That 2200 kv motor will most likely use a 6" prop. Put that motor on a small, speedy plane with the same battery sizes.

Come to think of it, I'm pretty sure the 2200 kv, A2212/6 is the same motor I have in my Bloody Wonder. Its a lot of fun with a 1000 mah, 4s battery! Its not rated for 4s, but it handles it just fine.
