Question Blow Up my Esc :3

Hello, I am new to RC Planes, and just bought the parts off eBay to get started.
I have not the most experience with building, so my plane was a bit overweight. Around 1.2 Kg, or 2.6 pounds.
My Components are:

Esc 30A, short peak up to 40A, The Description said: Max Speed 210,000rpm for 2 poles BLM, 70,000rpm for 6 poles BLM, 35,000rpm for 12 poles brushless Motor if this is of any use.
Li-Po 3S 11.1V 30C
Motor A2212/5T 2450KV 280W

So I tried to gently increase the throttle, and it seemed to have enough power, but halfway through the Esc started to cheep and short after it just popped, with smoke and everything.
So I wondered why this is? I mean if I do the maths, since the motor is 280Watt and the Battery has 11.1V the maximum flowing Current should be 280W/11.1V = 25.2A.
This should be fine for the Esc, shouldn't it? :O
My Plan for next time would be to get a bigger Esc and also make a lighter plane. But will this be the right way ? Or do I need to change something different.
If you could help me, so I don't waste another Esc, I would be very glad, Tanks
Best Regards
Alex
