quadcopter configuration opinion

Hi,
I'm newbie in quadcopter's world and I'm starting building my first one, I was undecided between 450mm and 250mm frame, so I decided for a F330 frame because I think it's a good compromise of stability/maneuverability for a versatile drone (fun flying/photographing).
I think there's enough space to carry what I need (a camera, maybe some sensor), so I can save weight then autonomy, and I can easily upgrade it to a 450mm frame only by changing arms and propellers.
On DJI site for the F330 frame they recommend 2212 motors and 8045 propellers, so I opted for 920Kv motors (like dji FlameWheel330):
- 8045 propellers
- 2212 920Kv motors
- 30A Simonk ESCs (for the future)
- MultiWii FC (I need one written in Arduino)
- 3000mAh 3S 20C LiPo

Furthermore, to prevent mid-flight shutdowns, I'm looking for a low battery voltage alarm, e.g. buzzer or led, do you know anyone?
and since I haven't it, is there a battery-ESCs connector with which I can avoid buying a soldering iron?

What do you think about this configuration?
If motors are ok , are there differences between various motors brands?
Otherwise, for what Kv or motor size should I look for, considering an eventual future upgrade to 450mm ?
Thanks
 
I know that is a must, I just wanted to know if are there alternatives connectors less "definitive".
 
Ok for sizes, and what about Kv?
Unfortunately it doesn't ship to my country, anyway these seem expensive, I've found others that cost 3 times less!
At equal sizes and Kv, what differentiates brands and costs? Efficiency?
 
Umm, that works out to $12 per motor. So if you've found 2212 900kv motors for $4 each well. good luck with that.
 
You can't even buy dys1806 for less than that. & there about the cheapest I'd go for. We think you need a rethink on them motors.
 
Is my first drone, these motors don't have to last a lifetime. If they fly well, they will be fine. I'm more interested to choose the right specs
 
I would stick to known Brands and reputable companies. I don't know if that was said later in this thread because due to my ADD I did not read all of it, but that would probably be your best bet. I bought a couple of cheap Motors off of eBay from some unknown company, and one sounded like a roller skate, and another lasted about 20 or 25 minutes before also sounding like a roller skate.
 
I have to buy a deans connector wire for the battery to solder to the bottom board, but online I read incongruity about AWG and ampacity, considering I have 30A ESCs which AWG I need ?

As both motors and ESCs have enough long wire, I'm thinking about putting the ESCs in the middle instead of on the arms to minimize wires slack , protect the ESCs inside, and have better center of gravity (maybe?), what do you think about it ?
