Ok guys, Last spring (2003) i built an Uproar 40 from tower hobbies and flew the crap out of it until i sold it in the winter of '03. It was powered by a 46FX and loved the way it flew. Totally regreating selling it, i am ready to build another one, this time, electric. My backround in electric isnt big, many small park flyers (slow sticks, wattage foamies, and other small 280-300 size brushed planes) but none of them dealing with brushless. Anyway, here is how i want to do it as i want about the same amount of power.

Axi 2826/12 with the jeti 40amp and a thunder power 3S2P 2100mah pack.
What my question really is is regarding power, will this fly a 3.5-4lb uproar? The site says it will but i fly at 5,480 absl. As you can tell, i am not very experienced in the electric department so any help or reccomendations would be awesome.

This was my old Uproar
