rc plane equipment

so i was looking for more power for my yak 55 foamie so i asked the guy at the hobby shop what motor i should get and i told him my esc was a 25 amp but it was actually a 15 amp. so he gave me a park 370 motor 1080 kv outrunner. to make a long story short it had less power than the stock outrunner. my question is what is the cheapest esc and 11.1 battery i can get.
(i want the most power i can get out of this little motor)
please

well u need a fagsnack esc so u can loolololololol it all to the same amount of power

sorry about that that was my bro

ok guys i got a 11.1 1350mah battery and thunderbird esc so the power to weight ratio is like 2.5:1 holy crap! so you dont have to worry about it anymore
